Configuration Guide

JBoss EAP 7 introduced a suspend mode, which suspends server operations gracefully. This allows all active requests to complete normally, but will not accept any new requests. Once the server has been suspended, it can be shut down, returned back to a running state, or left in a suspended state to perform maintenance.

The server can be suspended and resumed using the management console or the management CLI.

Check the Server Suspend State

The server suspend state can be viewed using the following management CLI commands. The resulting value will be one of RUNNING, PRE_SUSPEND, SUSPENDING, or SUSPENDED.

Suspend

Use the following management CLI commands to suspend the server, specifying the timeout value, in seconds, for the server to wait for active requests to complete. The default is 0, which will suspend immediately. A value of -1 will cause the server to wait indefinitely for all active requests to complete.

Each example waits up to 60 seconds for requests to complete before suspending.

Resume

The server can be returned back to a normal running state to accept new requests by using the resume command at the appropriate level (server, server group, entire domain). For example:

:resume

A server will be shut down gracefully if an appropriate timeout value is specified when stopping the server. Once the command is issued, the server will be suspended and will wait up to the specified timeout for all requests to finish before shutting down.

Use the following management CLI commands to shut down the server gracefully. Specify the timeout value, in seconds, for the server to wait for active requests to complete. The default is 0, which will shut down the server immediately. A value of -1 will cause the server to wait indefinitely for all active requests to complete before shutting down.

Each example waits up to 60 seconds for requests to complete before shutting down.

The command for starting an RPM installation of JBoss EAP depends on which operating mode you want to start (a standalone server or a managed domain), and which Red Hat Enterprise Linux version you are running.

Start JBoss EAP as a Standalone Server (RPM Installation)

This will start JBoss EAP using the standalone.xml configuration file by default. You can start JBoss EAP with a different standalone server configuration file by setting a property in the RPM service configuration file. For more information, see the Configure RPM Service Properties section below.

Start JBoss EAP in a Managed Domain (RPM Installation)

This will start JBoss EAP using the host.xml configuration file by default. You can start JBoss EAP with a different managed domain configuration file by setting a property in the RPM service configuration file. For more information, see the Configure RPM Service Properties section below.

Configure RPM Service Properties

This section shows you how to configure the RPM service properties and other startup options for your JBoss EAP installation. Note that it is recommended to back up your configuration files before making modifications.

For a listing of all available startup options for an RPM installation, see the RPM Service Configuration Properties section.

The command for stopping an RPM installation of JBoss EAP depends on which operating mode that was started (a standalone server or a managed domain), and which Red Hat Enterprise Linux version you are running.

Stop JBoss EAP as a Standalone Server (RPM Installation)

Stop JBoss EAP in a Managed Domain (RPM Installation)

For a listing of all available startup options for an RPM installation, see the RPM Service Configuration Files section.

Users can also be created non-interactively by passing parameters to the add-user script. This approach is not recommended on shared systems, because the passwords will be visible in log and history files. For more information, see Running the Add-User Utility Non-Interactively.

You can run the add-user script non-interactively by passing in arguments on the command line. At a minimum, the username and password must be provided.

Create a User Belonging to Multiple Groups

The following command adds a management user (mgmtuser1) with the guest and mgmtgroup groups.

$ EAP_HOME/bin/add-user.sh -u 'mgmtuser1' -p 'password1!' -g 'guest,mgmtgroup'

Specify an Alternative Properties File

By default, user and group information created using the add-user script are stored in properties files located in the server configuration directory.

User information is stored in the following properties files:

Group information is stored in the following properties files:

These default directories and properties file names can be overridden. The following command adds a new user, specifying a different name and location for the user properties files.

$ EAP_HOME/bin/add-user.sh -u 'mgmtuser2' -p 'password1!' -sc '/path/to/standaloneconfig/' -dc '/path/to/domainconfig/' -up 'newname.properties'

The new user was added to the user properties files now located at /path/to/standaloneconfig/newname.properties and /path/to/domainconfig/newname.properties. Note that these files must already exist or you will see an error.

For a complete listing of all available add-user arguments and their purposes, use the --help argument or see the Add-User Utility Arguments section.

The password restrictions for the add-user utility script can be configured using the EAP_HOME/bin/add-user.properties file.

By default, JBoss EAP allows weak passwords but will issue a warning. To reject passwords that do not meet the minimum requirements specified, set the password.restriction property to REJECT.

Additional password requirements that can be configured in the EAP_HOME/bin/add-user.properties file:

The management command-line interface (CLI) is a command-line administration tool for JBoss EAP.

Use the management CLI to start and stop servers, deploy and undeploy applications, configure system settings, and perform other administrative tasks. Operations can be performed in batch mode, allowing multiple tasks to be run as a group.

Many common terminal commands are available, such as ls, cd, and pwd. The management CLI also supports tab completion.

For detailed information on using the management CLI, including commands and operations, syntax, and running in batch mode, see the JBoss EAP Management CLI Guide.

Launch the Management CLI

$ EAP_HOME/bin/jboss-cli.sh

Connect to a Running Server

connect

Or you can launch the management CLI and connect in one step by using the EAP_HOME/bin/jboss-cli.sh --connect command.

Display Help

Use the following command for general help.

help

Use the following command for help on a specific command.

deploy --help

Quit the Management CLI

quit

View System Settings

The following command uses the read-attribute operation to display whether the example datasource is enabled.

/subsystem=datasources/data-source=ExampleDS:read-attribute(name=enabled)
{
    "outcome" => "success",
    "result" => true
}

When running in a managed domain, you must specify which profile to update by preceding the command with /profile=PROFILE_NAME.

/profile=default/subsystem=datasources/data-source=ExampleDS:read-attribute(name=enabled)

Update System Settings

The following command uses the write-attribute operation to disable the example datasource.

/subsystem=datasources/data-source=ExampleDS:write-attribute(name=enabled,value=false)

Start Servers

The management CLI can also be used to start and stop servers when running in a managed domain.

/host=HOST_NAME/server-config=server-one:start

The management console is a web-based administration tool for JBoss EAP.

Use the management console to start and stop servers, deploy and undeploy applications, tune system settings, and make persistent modifications to the server configuration. The management console also has the ability to perform administrative tasks, with live notifications when any changes performed by the current user require the server instance to be restarted or reloaded.

In a managed domain, server instances and server groups in the same domain can be centrally managed from the management console of the domain controller.

For a JBoss EAP instance running on the local host using the default management port, the management console can be accessed through a web browser at http://localhost:9990/console/App.html. You will need to authenticate with a user that has permissions to access the management console.

The management console provides the following tabs for navigating and managing your JBoss EAP standalone server or managed domain.

/core-service=management/management-interface=http-interface:write-attribute(name=console-enabled,value=true)

/core-service=management/management-interface=http-interface:write-attribute(name=console-enabled,value=false)

The HTTP API endpoint is the entry point for management clients that rely on the HTTP protocol to integrate with the JBoss EAP management layer.

The HTTP API is used by the JBoss EAP management console but offers integration capabilities for other clients as well. By default, the HTTP API is accessible at http://HOST_NAME:9990/management. This URL will display the raw attributes and values exposed to the API.

Read Resources

While you can read, write, or perform other operations using the HTTP POST method, you can perform some read operations using a GET request. The HTTP GET method uses the following URL format.

http://HOST_NAME:9990/management/PATH_TO_RESOURCE?operation=OPERATION&PARAMETER=VALUE

Be sure to replace all of the replaceable values with those that are appropriate for your request. The following values are the available options for the OPERATION replaceable value:

The following example URLs show how to perform read operations using the HTTP API.

http://HOST_NAME:9990/management/subsystem/undertow/server/default-server/http-listener/default

This displays all attributes and their values for the default HTTP listener.

http://HOST_NAME:9990/management/subsystem/datasources/data-source/ExampleDS?operation=attribute&name=enabled

This reads the value of the enabled attribute for the ExampleDS datasource.

Update Resources

You can use the HTTP POST method to update configuration values or perform other operations using the HTTP API. You must provide authentication for these operations.

The following examples show how to update resources using the HTTP API.

$ curl --digest http://HOST_NAME:9990/management --header "Content-Type: application/json" -u USERNAME:PASSWORD -d '{"operation":"write-attribute", "address":["subsystem","datasources","data-source","ExampleDS"], "name":"enabled", "value":"false", "json.pretty":"1"}'

This updates the value of the enabled attribute for the ExampleDS datasource to false.

$ curl --digest http://localhost:9990/management --header "Content-Type: application/json" -u USERNAME:PASSWORD -d '{"operation":"reload"}'

This reloads the server.

See Deploying Applications Using the HTTP API for information on how to deploy applications to JBoss EAP using the HTTP API.

The native API endpoint is the entry point for management clients that rely on the native protocol to integrate with the JBoss EAP management layer. The native API is used by the JBoss EAP management CLI but offers integration capabilities for other clients as well.

The following Java code shows an example of how to execute management operations from Java code using the native API.

// Create the management client
ModelControllerClient client = ModelControllerClient.Factory.create("localhost", 9990);

// Create the operation request
ModelNode op = new ModelNode();

// Set the operation
op.get("operation").set("read-resource");

// Set the address
ModelNode address = op.get("address");
address.add("subsystem", "undertow");
address.add("server", "default-server");
address.add("http-listener", "default");

// Execute the operation and manipulate the result
ModelNode returnVal = client.execute(op);
System.out.println("Outcome: " + returnVal.get("outcome").toString());
System.out.println("Result: " + returnVal.get("result").toString());

// Close the client
client.close();

The standalone configuration files are located in the EAP_HOME/standalone/configuration/ directory. A separate file exists for each of the four predefined profiles (default, ha, full, full-ha).

By default, starting JBoss EAP as a standalone server uses the standalone.xml file. To start JBoss EAP with a different configuration, use the --server-config argument. For example,

$ EAP_HOME/bin/standalone.sh --server-config=standalone-full.xml

The managed domain configuration files are located in the EAP_HOME/domain/configuration/ directory.

By default, starting JBoss EAP in a managed domain uses the host.xml file. To start JBoss EAP with a different configuration, use the --host-config argument. For example,

$ EAP_HOME/bin/domain.sh --host-config=host-master.xml

In order to later restore the JBoss EAP server configuration, items in the following locations should be backed up:

To assist in the maintenance and management of the server, JBoss EAP creates a timestamped version of the original configuration file at the time of startup. Any additional configuration changes made by management operations will result in the original file being automatically backed up, and a working copy of the instance being preserved for reference and rollback. Additionally, configuration snapshots can be taken, which are point-in-time copies of the current server configuration. These snapshots can be saved and loaded by an administrator.

The following examples use the standalone.xml file, but the same process applies to the domain.xml and host.xml files.

Take a Snapshot

Use the management CLI to take a snapshot of the current configurations.

:take-snapshot
{
    "outcome" => "success",
    "result" => "EAP_HOME/standalone/configuration/standalone_xml_history/snapshot/20151022-133109702standalone.xml"
}

List Snapshots

Use the management CLI to list all snapshots that have been taken.

:list-snapshots
{
    "outcome" => "success",
    "result" => {
        "directory" => "EAP_HOME/standalone/configuration/standalone_xml_history/snapshot",
        "names" => [
            "20151022-133109702standalone.xml",
            "20151022-132715958standalone.xml"
        ]
    }
}

Delete a Snapshot

Use the management CLI to delete a snapshot.

:delete-snapshot(name=20151022-133109702standalone.xml)

Start the Server with a Snapshot

The server can be started using a snapshot or an automatically-saved version of the configuration.

JBoss EAP 7 provides the ability to track configuration changes made to the running system. This allows administrators to view a history of configuration changes made by other authorized users.

To enable to tracking of configuration changes, use the following management CLI command. You can specify how many entries to store using the max-history attribute.

/core-service=management/service=configuration-changes:add(max-history=10)

To view the list of most recent configuration changes, use the following management CLI command.

/core-service=management/service=configuration-changes:list-changes

This will list each configuration change made, with the date, origin, outcome, and operation details. For example, the below output from the list-changes command shows configuration changes, with the most recent displayed first.

{
    "outcome" => "success",
    "result" => [
        {
            "operation-date" => "2016-02-12T18:37:00.354Z",
            "access-mechanism" => "NATIVE",
            "remote-address" => "127.0.0.1/127.0.0.1",
            "outcome" => "success",
            "operations" => [{
                "address" => [],
                "operation" => "reload",
                "operation-headers" => {
                    "caller-type" => "user",
                    "access-mechanism" => "NATIVE"
                }
            }]
        },
        {
            "operation-date" => "2016-02-12T18:34:16.859Z",
            "access-mechanism" => "NATIVE",
            "remote-address" => "127.0.0.1/127.0.0.1",
            "outcome" => "success",
            "operations" => [{
                "address" => [
                    ("subsystem" => "datasources"),
                    ("data-source" => "ExampleDS")
                ],
                "operation" => "write-attribute",
                "name" => "enabled",
                "value" => false,
                "operation-headers" => {
                    "caller-type" => "user",
                    "access-mechanism" => "NATIVE"
                }
            }]
        },
        {
            "operation-date" => "2016-02-12T18:24:11.670Z",
            "access-mechanism" => "HTTP",
            "remote-address" => "127.0.0.1/127.0.0.1",
            "outcome" => "success",
            "operations" => [{
                "operation" => "remove",
                "address" => [
                    ("subsystem" => "messaging-activemq"),
                    ("server" => "default"),
                    ("jms-queue" => "ExpiryQueue")
                ],
                "operation-headers" => {"access-mechanism" => "HTTP"}
            }]
        }
    ]
}

This example lists the details of three operations performed that impacted the configuration:

JBoss EAP allows you to use expressions to define replaceable properties in place of literal values in the configuration. Expressions use the format ${PARAMETER:DEFAULT_VALUE}. If the specified parameter is set, then the parameter’s value will be used. Otherwise, the default value provided will be used.

The supported sources for resolving expressions are system properties, environment variables, and the vault. For deployments only, the source can be properties listed in a META-INF/jboss.properties file in the deployment archive. For deployment types that support subdeployments, the resolution is scoped to all subdeployments if the properties file is in the outer deployment, for example the EAR. If the properties file is in the subdeployment, then the resolution is scoped just to that subdeployment.

The example below from the standalone.xml configuration file sets the inet-address for the public interface to 127.0.0.1 unless the jboss.bind.address parameter is set.

<interface name="public">
    <inet-address value="${jboss.bind.address:127.0.0.1}"/>
</interface>

The jboss.bind.address parameter can be set when starting EAP as a standalone server with the following command:

$ EAP_HOME/bin/standalone.sh -Djboss.bind.address=IP_ADDRESS

Nested Expressions

Expressions can be nested, which allows for more advanced use of expressions in place of fixed values. The format of a nested expression is like that of a normal expression, but one expression is embedded in the other, for example:

${SYSTEM_VALUE_1${SYSTEM_VALUE_2}}

Nested expressions are evaluated recursively, so the inner expression is first evaluated, then the outer expression is evaluated. Expressions may also be recursive, where an expression resolves to another expression, which is then resolved. Nested expressions are permitted anywhere that expressions are permitted, with the exception of management CLI commands.

An example of where a nested expression might be used is if the password used in a datasource definition is masked. The configuration for the datasource might have the following line:

<password>${VAULT::ds_ExampleDS::password::1}</password>

The value of ds_ExampleDS could be replaced with a system property (datasource_name) using a nested expression. The configuration for the datasource could instead have the following line:

<password>${VAULT::${datasource_name}::password::1}</password>

JBoss EAP would first evaluate the expression ${datasource_name}, then input this to the larger expression and evaluate the resulting expression. The advantage of this configuration is that the name of the datasource is abstracted from the fixed configuration.

Descriptor-Based Property Replacement

Application configuration, such as datasource connection parameters, typically varies between development, testing, and production environments. This variance is sometimes accommodated by build system scripts, as the Java EE specification does not contain a method to externalize these configurations. With JBoss EAP, you can use descriptor-based property replacement to manage configuration externally.

Descriptor-based property replacement substitutes properties based on descriptors, allowing you to remove assumptions about the environment from the application and the build chain. Environment-specific configurations can be specified in deployment descriptors rather than annotations or build system scripts. You can provide configuration in files or as parameters at the command line.

There are several flags in the ee subsystem that control whether property replacement is applied.

JBoss-specific descriptor replacement is controlled by the jboss-descriptor-property-replacement flag and is enabled by default. When enabled, properties can be replaced in the following deployment descriptors:

The following management CLI command can be used to enable or disable property replacement in JBoss-specific descriptors:

/subsystem=ee:write-attribute(name="jboss-descriptor-property-replacement",value=VALUE)

Java EE descriptor replacement controlled by the spec-descriptor-property-replacement flag and is disabled by default. When enabled, properties can be replaced in the following deployment descriptors:

The following management CLI command can be used to enable or disable property replacement in Java EE descriptors:

/subsystem=ee:write-attribute(name="spec-descriptor-property-replacement",value=VALUE)

You can override the default locations of the standard paths that begin with jboss.server.* or jboss.domain.*. This can be done in one of two ways:

Overriding a Managed Domain’s Standard Paths

In this example, the objective is to store domain files in the /opt/jboss_eap/domain_data directory, and give each top-level directory a custom name. The default directory grouping, by-server, is used.

To achieve this configuration, you would override several system properties when starting JBoss EAP.

$ EAP_HOME/bin/domain.sh -Djboss.domain.temp.dir=/opt/jboss_eap/domain_data/all_temp -Djboss.domain.log.dir=/opt/jboss_eap/domain_data/all_logs -Djboss.domain.data.dir=/opt/jboss_eap/domain_data/all_data -Djboss.domain.servers.dir=/opt/jboss_eap/domain_data/all_servers

The resulting path structure will be as follows:

/opt/jboss_eap/domain_data/
               ├── all_data
               ├── all_logs
               ├── all_servers
               │   ├── server-one
               │   │   ├── data
               │   │   ├── log
               │   │   └── tmp
               │   └── server-two
               │       ├── data
               │       ├── log
               │       └── tmp
               └── all_temp

You can add a custom file system path using the management CLI or the management console.

You can then use this custom path in your configuration. For example, the below log handler uses a custom path for its relative path.

<subsystem xmlns="urn:jboss:domain:logging:3.0">
  ...
  <periodic-rotating-file-handler name="FILE" autoflush="true">
    <formatter>
      <named-formatter name="PATTERN"/>
    </formatter>
    <file relative-to="my.custom.path" path="server.log"/>
    <suffix value=".yyyy-MM-dd"/>
    <append value="true"/>
  </periodic-rotating-file-handler>
  ...
</subsystem>

In a managed domain, each server’s files are stored in the EAP_HOME/domain directory. You can specify how to organize the subdirectories for servers using the host controller’s directory-grouping attribute. Directories can be grouped either by server or by type. By default, directories are grouped by server.

Directory Grouping by Server

By default, directories are grouped by server. If your administration is server-centric, this configuration is recommended. For example, it allows backups and log file handling to be configured per server instance.

If JBoss EAP is installed using the ZIP installation method, the default directory structure (grouped by server) will be as follows.

EAP_HOME/domain
         └─ servers
            ├── server-one
            │   ├── data
            │   ├── tmp
            │   └── log
            └── server-two
                ├── data
                ├── tmp
                └── log

To group domain directories by server, enter the following management CLI command:

/host=HOST_NAME:write-attribute(name=directory-grouping,value=by-server)

This will update the host controller’s host.xml configuration file:

<servers directory-grouping="by-server">
  <server name="server-one" group="main-server-group"/>
  <server name="server-two" group="main-server-group" auto-start="true">
    <socket-bindings port-offset="150"/>
  </server>
</servers>

Directory Grouping by Type

Instead of grouping directories by server, you can instead group by file type. If your administration is file type-centric, this configuration is recommended. For example, this would allow you to easily back up only data files.

If JBoss EAP is installed using the ZIP installation method and the domain’s files are grouped by type, the directory structure will be as follows.

EAP_HOME/domain
         ├── data
         │   └── servers
         │       ├── server-one
         │       └── server-two
         ├── log
         │   └── servers
         │       ├── server-one
         │       └── server-two
         └── tmp
             └── servers
                 ├── server-one
                 └── server-two

To group domain directories by type, enter the following management CLI command:

/host=HOST_NAME:write-attribute(name=directory-grouping,value=by-type)

This will update the host controller’s host.xml configuration file:

<servers directory-grouping="by-type">
  <server name="server-one" group="main-server-group"/>
  <server name="server-two" group="main-server-group" auto-start="true">
    <socket-bindings port-offset="150"/>
  </server>
</servers>

JBoss EAP is preconfigured with file handlers for audit logging, though audit logging is disabled by default. The management CLI command to enable audit logging depends on whether you are running as a standalone server or in a managed domain. See Management Audit Logging Attributes for file handler attributes.

To set up syslog audit logging, see Set Up Management Audit Logging to a Syslog Server.

Enable Standalone Server Audit Logging

Audit logging can be enabled using the following command.

/core-service=management/access=audit/logger=audit-log:write-attribute(name=enabled,value=true)

By default, this will write the audit log to EAP_HOME/standalone/data/audit-log.log.

Enable Managed Domain Audit Logging

The default audit logging configuration for a managed domain is preconfigured to write an audit log for each host and each server.

Audit logging for each host can be enabled using the following command.

/host=HOST_NAME/core-service=management/access=audit/logger=audit-log:write-attribute(name=enabled,value=true)

By default, this will write the audit logs to EAP_HOME/domain/data/audit-log.log.

Audit logging for each server can be enabled using the following command.

/host=HOST_NAME/core-service=management/access=audit/server-logger=audit-log:write-attribute(name=enabled,value=true)

By default, this will write the audit logs to EAP_HOME/domain/servers/SERVER_NAME/data/audit-log.log

A syslog handler specifies the parameters by which audit log entries are sent to a syslog server, specifically the syslog server’s host name and the port on which the syslog server is listening. Sending audit logging to a syslog server provides more security options than logging to a local file or local syslog server. Multiple syslog handlers can be defined and be active at the same time.

By default, audit logging is preconfigured to output to a file when enabled. Use the following steps to set up and enable audit logging to a syslog server. See Management Audit Logging Attributes for syslog handler attributes.

Audit log entries output to files are best viewed with a text viewer, while those output to a syslog server are best viewed using a syslog viewer application.

The audit log entries are stored in JSON format. Each log entry begins with an optional timestamp, followed by the fields in the below table.

By default, JBoss EAP binds these interfaces to 127.0.0.1, but these values can be overridden at runtime by setting the appropriate property. For example, the inet-address of the public interface can be set when starting JBoss EAP as a standalone server with the following command.

$ EAP_HOME/bin/standalone.sh -Djboss.bind.address=IP_ADDRESS

Alternatively, you can use the -b switch on the server start command line. For more information about server start options, see Server Runtime Arguments.

Network interfaces are declared by specifying a logical name and selection criteria for the physical interface. The selection criteria can reference a wildcard address or specify a set of one or more characteristics that an interface or address must have in order to be a valid match. For a listing of all available interface selection criteria, see the Interface Attributes section.

Interfaces can be configured using the management console or the management CLI. Below are several examples of adding and updating interfaces. The management CLI command is shown first, followed by the corresponding configuration XML.

Add an Interface with a NIC Value

Add a new interface with a NIC value of eth0.

/interface=external:add(nic=eth0)

<interface name="external">
   <nic name="eth0"/>
</interface>

Add an Interface with Several Conditional Values

Add a new interface that matches any interface/address on the correct subnet if it is up, supports multicast, and is not point-to-point.

/interface=default:add(subnet-match=192.168.0.0/16,up=true,multicast=true,not={point-to-point=true})

<interface name="default">
   <subnet-match value="192.168.0.0/16"/>
   <up/>
   <multicast/>
   <not>
      <point-to-point/>
   </not>
</interface>

Update an Interface Attribute

Update the public interface’s default inet-address value, keeping the jboss.bind.address property to allow for this value to be set at runtime.

/interface=public:write-attribute(name=inet-address,value="${jboss.bind.address:192.168.0.0}")

<interface name="public">
    <inet-address value="${jboss.bind.address:192.168.0.0}"/>
</interface>

Add an Interface to a Server in a Managed Domain

/host=master/server-config=SERVER_NAME/interface=INTERFACE_NAME:add(inet-address=127.0.0.1)

<servers>
   <server name="SERVER_NAME" group="main-server-group">
      <interfaces>
         <interface name="INTERFACE_NAME">
            <inet-address value="127.0.0.1"/>
         </interface>
      </interfaces>
   </server>
</servers>

Management ports were consolidated in JBoss EAP 7. By default, JBoss EAP 7 uses port 9990 for both native management, used by the management CLI, and HTTP management, used by the web-based management console. Port 9999, which was used as the native management port in JBoss EAP 6, is no longer used but can still be enabled if desired.

If HTTPS is enabled for the management console, then port 9993 is used by default.

JBoss EAP ships with a socket binding group for each of the four predefined profiles (default, ha, full, full-ha).

For detailed information about the default socket bindings, such as default ports and descriptions, see the Default Socket Bindings section.

Standalone Server

When running as a standalone server, only one socket binding group is defined per configuration file. Each standalone configuration file (standalone.xml, standalone-ha.xml, standalone-full.xml, standalone-full-ha.xml) defines socket bindings for the technologies used by its corresponding profile.

For example, the default standalone configuration file (standalone.xml) specifies the below socket bindings.

<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
    <socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>
    <socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9993}"/>
    <socket-binding name="ajp" port="${jboss.ajp.port:8009}"/>
    <socket-binding name="http" port="${jboss.http.port:8080}"/>
    <socket-binding name="https" port="${jboss.https.port:8443}"/>
    <socket-binding name="txn-recovery-environment" port="4712"/>
    <socket-binding name="txn-status-manager" port="4713"/>
    <outbound-socket-binding name="mail-smtp">
        <remote-destination host="localhost" port="25"/>
    </outbound-socket-binding>
</socket-binding-group>

Managed Domain

When running in a managed domain, all socket binding groups are defined in the domain.xml file. There are four predefined socket binding groups:

Each socket binding group specifies socket bindings for the technologies used by its corresponding profile. For example, the full-ha-sockets socket binding group defines several jgroups socket bindings, which are used by the full-ha profile for high availability.

<socket-binding-groups>
    <socket-binding-group name="standard-sockets" default-interface="public">
        <!-- Needed for server groups using the 'default' profile  -->
        <socket-binding name="ajp" port="${jboss.ajp.port:8009}"/>
        <socket-binding name="http" port="${jboss.http.port:8080}"/>
        <socket-binding name="https" port="${jboss.https.port:8443}"/>
        <socket-binding name="txn-recovery-environment" port="4712"/>
        <socket-binding name="txn-status-manager" port="4713"/>
        <outbound-socket-binding name="mail-smtp">
            <remote-destination host="localhost" port="25"/>
        </outbound-socket-binding>
    </socket-binding-group>
    <socket-binding-group name="ha-sockets" default-interface="public">
        <!-- Needed for server groups using the 'ha' profile  -->
    ...
    </socket-binding-group>
    <socket-binding-group name="full-sockets" default-interface="public">
        <!-- Needed for server groups using the 'full' profile  -->
    ...
    </socket-binding-group>
    <socket-binding-group name="full-ha-sockets" default-interface="public">
        <!-- Needed for server groups using the 'full-ha' profile  -->
        <socket-binding name="ajp" port="${jboss.ajp.port:8009}"/>
        <socket-binding name="http" port="${jboss.http.port:8080}"/>
        <socket-binding name="https" port="${jboss.https.port:8443}"/>
        <socket-binding name="iiop" interface="unsecure" port="3528"/>
        <socket-binding name="iiop-ssl" interface="unsecure" port="3529"/>
        <socket-binding name="jgroups-mping" interface="private" port="0" multicast-address="${jboss.default.multicast.address:230.0.0.4}" multicast-port="45700"/>
        <socket-binding name="jgroups-tcp" interface="private" port="7600"/>
        <socket-binding name="jgroups-tcp-fd" interface="private" port="57600"/>
        <socket-binding name="jgroups-udp" interface="private" port="55200" multicast-address="${jboss.default.multicast.address:230.0.0.4}" multicast-port="45688"/>
        <socket-binding name="jgroups-udp-fd" interface="private" port="54200"/>
        <socket-binding name="modcluster" port="0" multicast-address="224.0.1.105" multicast-port="23364"/>
        <socket-binding name="txn-recovery-environment" port="4712"/>
        <socket-binding name="txn-status-manager" port="4713"/>
        <outbound-socket-binding name="mail-smtp">
            <remote-destination host="localhost" port="25"/>
        </outbound-socket-binding>
    </socket-binding-group>
</socket-binding-groups>

When defining a socket binding, you can configure the port and interface attributes, as well as multicast settings such as multicast-address and multicast-port. For details on all available socket bindings attributes, see the Socket Binding Attributes section.

Socket bindings can be configured using the management console or the management CLI. The following steps go through adding a socket binding group, adding a socket binding, and configuring socket binding settings using the management CLI.

The following example shows how the XML configuration may look after the above steps have been completed.

<socket-binding-groups>
    ...
    <socket-binding-group name="new-sockets" default-interface="public">
        <socket-binding name="new-socket-binding" interface="unsecure" port="1234"/>
    </socket-binding-group>
</socket-binding-groups>

A port offset is a numeric offset value added to all port values specified in the socket binding group for that server. This allows the server to inherit the port values defined in its socket binding group, with an offset to ensure that it does not conflict with any other servers on the same host. For instance, if the HTTP port of the socket binding group is 8080, and a server uses a port offset of 100, then its HTTP port is 8180.

Below is an example of setting a port offset of 250 for a server in a managed domain using the management CLI.

/host=master/server-config=server-two/:write-attribute(name=socket-binding-port-offset,value=250)

Port offsets can be used for servers in a managed domain and for running multiple standalone servers on the same host.

You can pass in a port offset when starting a standalone server using the jboss.socket.binding.port-offset property.

$ EAP_HOME/bin/standalone.sh -Djboss.socket.binding.port-offset=100

Deploy an Application

From the management CLI, use the deploy command and specify the path to the application deployment.

deploy /path/to/test-application.war

A successful deployment does not produce any output to the management CLI, but the server log displays deployment messages.

WFLYSRV0027: Starting deployment of "test-application.war" (runtime-name: "test-application.war")
WFLYUT0021: Registered web context: /test-application
WFLYSRV0010: Deployed "test-application.war" (runtime-name : "test-application.war")

The application has been successfully deployed.

Undeploy an Application

From the management CLI, use the undeploy command and specify the deployment name.

A successful undeployment does not produce any output to the management CLI, but the server log displays undeployment messages.

WFLYUT0022: Unregistered web context: /test-application
WFLYSRV0028: Stopped deployment test-application.war (runtime-name: test-application.war) in 62ms
WFLYSRV0009: Undeployed "test-application.war" (runtime-name: "test-application.war")

The application has been successfully undeployed.

List Deployments

From the management CLI, use the deployment-info command to list deployment information.

deployment-info

The output will show details about each deployment, such as the runtime name, status, and whether it is enabled.

NAME                 RUNTIME-NAME         PERSISTENT ENABLED STATUS
jboss-helloworld.war jboss-helloworld.war true       true    OK
test-application.war test-application.war true       true    OK

You can also filter the deployments to display by name using the --name argument.

Deploy an Application

From the management CLI, use the deploy command and specify the path to the application deployment. You must also specify the server groups to which the application should be deployed.

A successful deployment does not produce any output to the management CLI, but the server log displays deployment messages for each affected server.

[Server:server-one] WFLYSRV0027: Starting deployment of "test-application.war" (runtime-name: "test-application.war")
[Server:server-one] WFLYUT0021: Registered web context: /test-application
[Server:server-one] WFLYSRV0010: Deployed "test-application.war" (runtime-name : "test-application.war")

The application has been successfully deployed to the appropriate server groups in your managed domain.

Undeploy an Application

From the management CLI, use the undeploy command and specify the deployment name. You must also specify the server groups from which the application should be undeployed.

A successful undeployment does not produce any output to the management CLI, but the server log displays undeployment messages for each affected server.

[Server:server-one] WFLYUT0022: Unregistered web context: /test-application
[Server:server-one] WFLYSRV0028: Stopped deployment test-application.war (runtime-name: test-application.war) in 74ms
[Server:server-one] WFLYSRV0009: Undeployed "test-application.war" (runtime-name: "test-application.war")

The application has been successfully undeployed.

List Deployments

From the management CLI, use the deployment-info command to list deployment information. You can list deployment information by deployment name or by server group.

To display deployment information by name:

deployment-info --name=jboss-helloworld.war

The output will list the deployment and its state in each server group.

NAME                 RUNTIME-NAME
jboss-helloworld.war jboss-helloworld.war

SERVER-GROUP       STATE
main-server-group  enabled
other-server-group added

To display deployment information by server group:

deployment-info --server-group=other-server-group

The output will list the deployments and their state for the specified server group.

NAME                 RUNTIME-NAME         STATE
jboss-helloworld.war jboss-helloworld.war added
test-application.war test-application.war enabled

You can also list all deployments in the domain using the deploy -l command.

Deployments can be viewed and managed from the Deployments tab of the JBoss EAP management console.

Deploy an Application

Click the Add button and use the New Deployment wizard to deploy an application. You can choose to deploy an application by uploading a deployment or creating an unmanaged deployment. Deployments are enabled by default.

Undeploy an Application

Select the deployment and choose the Remove option to undeploy the application. This undeploys the deployment and removes it from the content repository.

Disable an Application

Select the deployment and choose the Disable option to disable the application. This undeploys the deployment, but does not remove it from the content repository.

Replace an Application

Select the deployment and choose the Replace option. Select the new version of the deployment, which must have the same name as the original, and click Finish. This undeploys and removes the original version of the deployment, and then deploys the new version.

From the Deployments tab of the JBoss EAP management console, deployments can be viewed and managed by:

Deploy an Application

Deployments can also be added, assigned to a server group, and enabled in one step by adding the deployment from Server Groups.

Assign an Application to a Server Group

Unassign an Application from a Server Group

Deployments can also be unassigned from multiple server groups at once by selecting the Unassign button for the deployment in Content Repository.

Undeploy an Application

This undeploys the deployment and removes it from the content repository.

Disable an Application

This undeploys the deployment, but does not remove it from the content repository.

Replace an Application

This undeploys and removes the original version of the deployment, and then deploys the new version.

The deployment scanner can be configured to allow or disallow automatic deployment of XML, zipped, and exploded content. If automatic deployment is disabled, you must manually create marker files to trigger deployment actions. For more information about the available marker file types and their purposes, see the Deployment Scanner Marker Files section.

By default, automatic deployment for XML and zipped content is enabled. For details on configuring automatic deployment for each content type, see Configure the Deployment Scanner.

Deploy an Application

Copy the content to the deployment folder.

$ cp /path/to/test-application.war EAP_HOME/standalone/deployments/

If auto-deployment is enabled, this file will be picked up automatically, deployed, and a .deployed marker file will be created. If auto-deployment is not enabled, then you will need to manually add a .dodeploy marker file to trigger deployment.

$ touch EAP_HOME/standalone/deployments/test-application.war.dodeploy

Undeploy an Application

Trigger an undeployment by removing the .deployed marker file.

$ rm EAP_HOME/standalone/deployments/test-application.war.deployed

If auto-deployment is enabled, you can also remove the test-application.war file, which will trigger the undeployment. Note that this does not apply for exploded deployments.

Redeploy an Application

Create a .dodeploy marker file to initiate redeployment.

$ touch EAP_HOME/standalone/deployments/test-application.war.dodeploy

The deployment scanner can be configured using the management console or the management CLI. You can configure the deployment scanner’s behavior, such as the scan interval, deployment folder location, and autodeployment of certain application file types. You can also disable the deployment scanner entirely.

For details on all available deployment scanner attributes, see the Deployment Scanner Attributes section.

Use the below management CLI commands to configure the default deployment scanner.

Disable the Deployment Scanner

/subsystem=deployment-scanner/scanner=default:write-attribute(name=scan-enabled,value=false)

This disables the default deployment scanner.

Change the Scan Interval

/subsystem=deployment-scanner/scanner=default:write-attribute(name=scan-interval,value=10000)

This updates the scan interval time from 5000 milliseconds (five seconds) to 10000 milliseconds (ten seconds).

Change the Deployment Folder

/subsystem=deployment-scanner/scanner=default:write-attribute(name=path,value=/path/to/deployments)

This changes the location of the deployment folder from the default location of EAP_HOME/standalone/deployments to /path/to/deployments.

The path value will be treated as an absolute path unless the relative-to attribute is specified, in which case it will be relative to that path.

Enable the Automatic Deployment of Exploded Content

/subsystem=deployment-scanner/scanner=default:write-attribute(name=auto-deploy-exploded,value=true)

This enables the automatic deployment of exploded content, which is disabled by default.

Disable the Automatic Deployment of Zipped Content

/subsystem=deployment-scanner/scanner=default:write-attribute(name=auto-deploy-zipped,value=false)

This disables the automatic deployment of zipped content, which is enabled by default.

Disable the Automatic Deployment of XML Content

/subsystem=deployment-scanner/scanner=default:write-attribute(name=auto-deploy-xml,value=false)

This disables the automatic deployment of XML content, which is enabled by default.

A new deployment scanner can be added using the management CLI or by navigating to the Deployment Scanners subsystem from the Configuration tab in the management console. This will define a new directory to scan for deployments. The default deployment scanner monitors EAP_HOME/standalone/deployments. See Configure the Deployment Scanner for details on configuring an existing deployment scanner.

The following management CLI command adds a new deployment scanner that will check EAP_HOME/standalone/new_deployment_dir every five seconds for deployments.

/subsystem=deployment-scanner/scanner=new-scanner:add(path=new_deployment_dir,relative-to=jboss.server.base.dir,scan-interval=5000)

A new deployment scanner has been defined and the specified directory will be monitored for deployments.

You can define a custom location for JBoss EAP to store deployed content.

Define a Custom Directory for a Standalone Server

By default, deployed content for a standalone server is stored in the EAP_HOME/standalone/data/content directory. This location can be changed by passing in the -Djboss.server.deploy.dir argument when starting the server.

$ EAP_HOME/bin/standalone.sh -Djboss.server.deploy.dir=/path/to/new_deployed_content

The chosen location should be unique among JBoss EAP instances.

Define a Custom Directory for a Managed Domain

By default, deployed content for a managed domain is stored in the EAP_HOME/domain/data/content directory. This location can be changed by passing in the -Djboss.domain.deployment.dir argument when starting the domain.

$ EAP_HOME/bin/domain.sh -Djboss.domain.deployment.dir=/path/to/new_deployed_content

The chosen location should be unique among JBoss EAP instances.

JBoss EAP offers fine-grained control over the order of deployments when the server is started. Strict order of the deployment of applications present in multiple EAR files can be specified along with persistence of the order after a restart.

You can use the jboss-all.xml deployment descriptor to declare dependencies between top-level deployments.

For example, if you have an app.ear that depends on framework.ear being deployed first, then you can create an app.ear/META-INF/jboss-all.xml file as shown below.

<jboss umlns="urn:jboss:1.0">
  <jboss-deployment-dependencies xmlns="urn:jboss:deployment-dependencies:1.0">
    <dependency name="framework.ear" />
  </jboss-deployment-dependencies>
</jboss>

This ensures that framework.ear is deployed before app.ear.

A deployment overlay can be used to overlay content into an existing deployment without physically modifying the contents of the deployment archive. It allows you to override deployment descriptors, JAR files, classes, JSP pages, and other files at runtime without rebuilding the archive.

This can be useful if you need to adapt a deployment for different environments that need different configurations or settings. For example, when moving a deployment through the application lifecycle from development, to testing, to stage, and finally into production, you might want to swap deployment descriptors, modify static web resources to change the branding of the application, or even replace JAR libraries with different versions depending on the target environment. It is also a useful feature for installations that need to change a configuration but can not modify or crack an archive due to policy or security restrictions.

When defining a deployment overlay, you specify the file on a file system that will replace the file in the deployment archive. You must also specify which deployments should be affected by the deployment overlay. Any affected deployments must be redeployed in order for the changes to take effect.

Use the deployment-overlay add management CLI command to add a deployment overlay.

deployment-overlay add --name=new-deployment-overlay --content=WEB-INF/web.xml=/path/to/other/web.xml --deployments=test-application.war --redeploy-affected

Once created, you can add content to an existing overlay, link the overlay to a deployment, or remove the overlay. For full usage details, execute deployment-overlay --help.

About Rollout Plans

In a managed domain, operations targeted at domain or host level resources can potentially impact multiple servers. Such operations can include a roll out plan detailing the sequence in which the operation would be applied to the servers, as well as the policies for detailing whether the operation could be reverted if it fails to execute successfully on some servers. If no rollout plan is specified, the default rollout plan is used.

Below is an example rollout plan involving five server groups. Operations can be applied to server groups serially (in-series) or concurrently (concurrent-groups). The syntax is described in more detail in Rollout Plan Syntax.

{"my-rollout-plan" => {"rollout-plan" => {
    "in-series" => [
        {"concurrent-groups" => {
            "group-A" => {
                "max-failure-percentage" => "20",
                "rolling-to-servers" => "true"
            },
            "group-B" => undefined
        }},
        {"server-group" => {"group-C" => {
            "rolling-to-servers" => "false",
            "max-failed-servers" => "1"
        }}},
        {"concurrent-groups" => {
            "group-D" => {
                "max-failure-percentage" => "20",
                "rolling-to-servers" => "true"
            },
            "group-E" => undefined
        }}
    ],
    "rollback-across-groups" => "true"
}}}

Looking at the example above, applying the operation to the servers in the domain is done in three phases. If the policy for any server group triggers a rollback of the operation across the server group, all other server groups will be rolled back as well.

Rollout Plan Syntax

You can specify a rollout plan in either of the following ways.

Although each method has a different initial command, both methods use the rollout operation header to define the rollout plan. This uses the following syntax.

rollout (id=PLAN_NAME | SERVER_GROUP_LIST) [rollback-across-groups]

Deploy Using a Rollout Plan

You can provide the full details of a rollout plan directly to the deploy command by passing the rollout settings into the headers argument. See the Rollout Plan Syntax for more information on the format.

The following management CLI command deploys an application to the main-server-group server group using a deployment plan that specifies rolling-to-servers=true for serial deployment.

deploy /path/to/test-application.war --server-groups=main-server-group --headers={rollout main-server-group(rolling-to-servers=true)}

Deploy Using a Stored Rollout Plan

Since rollout plans can be complex, you have the option to store the details of a rollout plan. This allows you to reference the rollout plan name when you want to use it instead of requiring the full details of the rollout plan each time.

Remove a Stored Rollout Plan

You can remove a stored rollout plan using the rollout-plan management CLI command by specifying the name of the rollout plan to remove.

rollout-plan remove --name=my-rollout-plan

Default Rollout Plan

All operations that impact multiple servers will be executed with a rollout plan. If no rollout plan is specified in the operation request, a default rollout plan will be generated. The plan will have the following characteristics.

A domain controller is the JBoss EAP server instance that acts as a central management point for a domain. One host controller instance is configured to act as a domain controller.

The primary responsibilities of the domain controller are:

By default, the central management policy is stored in the EAP_HOME/domain/configuration/domain.xml file. This file is required in this directory of the host controller that is set to run as the domain controller.

The domain.xml file contains profile configurations available for use by the servers in the domain. A profile contains the detailed settings of the various subsystems available in that profile. The domain configuration also includes the definition of socket groups and the server group definitions.

For more information, see the Start a Managed Domain and Configure the Domain Controller sections.

The primary responsibility of a host controller is server management. It delegates domain management tasks and is responsible for starting and stopping the individual application server processes that run on its host.

It interacts with the domain controller to help manage the communication between the servers and the domain controller. Multiple host controllers of a domain can interact with only a single domain controller. Hence, all the host controllers and server instances running on a single domain mode have a single domain controller and must belong to the same domain.

By default, each host controller reads its configuration from the EAP_HOME/domain/configuration/host.xml file located in the unzipped JBoss EAP installation file on its host’s file system. The host.xml file contains the following configuration information that is specific to the particular host:

For more information, see the Start a Managed Domain and Configure Host Controllers sections.

A process controller is a small, lightweight process that is responsible for spawning the host controller process and monitoring its lifecycle. If the host controller crashes, the process controller will restart it. It also starts server processes as directed by the host controller; however, it will not automatically restart server processes that crash.

The process controller logs to the EAP_HOME/domain/log/process-controller.log file. You can set JVM options for the process controller in the EAP_HOME/bin/domain.conf file using the PROCESS_CONTROLLER_JAVA_OPTS variable.

A server group is a collection of server instances that are managed and configured as one. In a managed domain, every application server instance belongs to a server group, even if it is the only member. The server instances in a group share the same profile configuration and deployed content.

A domain controller and a host controller enforce the standard configuration on all server instances of every server group in its domain.

A domain can consist of multiple server groups. Different server groups can be configured with different profiles and deployments. A domain can be configured with different server tiers providing different services, for example.

Different server groups can also have the same profile and deployments. This can, for example, allow for rolling application upgrades where the application is upgraded on one server group and then updated on a second server group, avoiding a complete service outage.

For more information, see the Configuring Server Groups section.

A server represents an application server instance. In a managed domain, all server instances are members of a server group. The host controller launches each server instance in its own JVM process.

For more information, see the Configuring Servers section.

Domain and host controllers can be started using the domain.sh or domain.bat script provided with JBoss EAP. For a complete listing of all available startup script arguments and their purposes, use the --help argument or see the Server Runtime Arguments section.

The domain controller must be started before any slave servers in any server groups in the domain. Start the domain controller first, then start any other associated host controllers in the domain.

Start the Domain Controller

Start the domain controller with the host-master.xml configuration file, which is preconfigured for a dedicated domain controller.

$ EAP_HOME/bin/domain.sh --host-config=host-master.xml

Depending on your domain setup, you will need to make additional configurations to allow host controllers to connect. Also see the following example domain setups:

Start a Host Controller

Start the host controller with the host-slave.xml configuration file, which is preconfigured for a slave host controller.

$ EAP_HOME/bin/domain.sh  --host-config=host-slave.xml

Depending on your domain setup, you will need to make additional configurations connect to, and not conflict with, the domain controller. Also see the following example domain setups:

Configure a Host to Act as the Domain Controller

A host is designated to be the domain controller if it includes the <local/> element in the <domain-controller> declaration.

<domain-controller>
  <local/>
</domain-controller>

The host acting as the domain controller must expose a management interface that is accessible to other hosts in the domain. It is not required to expose an HTTP(S) management interface, but is recommended as it allows access to the management console.

<management-interfaces>
  <native-interface security-realm="ManagementRealm">
    <socket interface="management" port="${jboss.management.native.port:9999}"/>
  </native-interface>
  <http-interface security-realm="ManagementRealm" http-upgrade-enabled="true">
    <socket interface="management" port="${jboss.management.http.port:9990}"/>
  </http-interface>
</management-interfaces>

The EAP_HOME/domain/configuration/host-master.xml file is already preconfigured with these settings to act as the domain controller.

Connect to the Domain Controller

A host controller must be provided with the means to connect to the domain controller so that it can register itself with the domain. This is configured in the <domain-controller> element of the configuration.

<domain-controller>
  <remote security-realm="ManagementRealm">
    <discovery-options>
      <static-discovery name="primary" protocol="${jboss.domain.master.protocol:remote}" host="${jboss.domain.master.address}" port="${jboss.domain.master.port:9999}"/>
    </discovery-options>
  </remote>
</domain-controller>

The EAP_HOME/domain/configuration/host-slave.xml file is already preconfigured with these settings to connect to the domain controller. You will need to provide the jboss.domain.master.address property when starting the host controller.

$ EAP_HOME/bin/domain.sh --host-config=host-slave.xml -Djboss.domain.master.address=IP_ADDRESS

For more information on domain controller discovery, see the Domain Controller Discovery and Failover section.

Depending on your domain setup, you may also need to provide authentication for the host controller to be authenticated by the domain controller. See Set Up a Managed Domain on Two Machines for details on generating a management user with a secret value and updating the host controller configuration with that value.

<host xmlns="urn:jboss:domain:4.0" name="host1">

$ EAP_HOME/bin/domain.sh --host-config=host-slave.xml  -Djboss.host.name=HOST_NAME

When setting up a managed domain, each host controller must be configured with information needed to contact the domain controller. In JBoss EAP, each host controller can be configured with multiple options for finding the domain controller. Host controllers iterate through the list of options until one succeeds.

This allows host controllers to be preconfigured with contact information for a backup domain controller. A backup host controller can be promoted to master if there is a problem with the primary domain controller, allowing host controllers to automatically fail over to the new master once it’s been promoted.

The following is an example of how to configure a host controller with multiple options for finding the domain controller.

<domain-controller>
  <remote security-realm="ManagementRealm">
    <discovery-options>
      <static-discovery name="primary" protocol="${jboss.domain.master.protocol:remote}" host="172.16.81.100" port="${jboss.domain.master.port:9999}"/>
      <static-discovery name="backup" protocol="${jboss.domain.master.protocol:remote}" host="172.16.81.101" port="${jboss.domain.master.port:9999}"/>
    </discovery-options>
  </remote>
</domain-controller>

A static discovery option includes the following required attributes:

In the example above, the first discovery option is the one expected to succeed. The second can be used in failover situations.

If a problem arises with the primary domain controller, a host controller that was started with the --backup option can be promoted to act as the domain controller.

Promote a Host Controller to Be the Domain Controller

This host controller will now act as the domain controller.

The following is an example of a server group definition:

<server-group name="main-server-group" profile="full">
  <jvm name="default">
    <heap size="64m" max-size="512m"/>
  </jvm>
  <socket-binding-group ref="full-sockets"/>
  <deployments>
    <deployment name="test-application.war" runtime-name="test-application.war"/>
    <deployment name="jboss-helloworld.war" runtime-name="jboss-helloworld.war" enabled="false"/>
  </deployments>
</server-group>

Server groups can be configured using the management CLI or from the management console Runtime tab.

Add a Server Group

The following management CLI command can be used to add a server group.

/server-group=SERVER_GROUP_NAME:add(profile=PROFILE_NAME,socket-binding-group=SOCKET_BINDING_GROUP_NAME)

Update a Server Group

The following management CLI command can be used to update server group attributes.

/server-group=SERVER_GROUP_NAME:write-attribute(name=ATTRIBUTE_NAME,value=VALUE)

Remove a Server Group

The following management CLI command can be used to remove a server group.

/server-group=SERVER_GROUP_NAME:remove

Server Group Attributes

A server group requires the following attributes:

A server group includes the following optional attributes:

The default host.xml configuration file defines three servers:

<servers>
  <server name="server-one" group="main-server-group">
  </server>
  <server name="server-two" group="main-server-group" auto-start="true">
    <socket-bindings port-offset="150"/>
  </server>
  <server name="server-three" group="other-server-group" auto-start="false">
    <socket-bindings port-offset="250"/>
  </server>
</servers>

A server instance named server-one is associated with main-server-group and inherits the subsystem configuration and socket bindings specified by that server group. A server instance named server-two is also associated with main-server-group, but also defines a socket binding port-offset value, so as not to conflict with the port values used by server-one. A server instance named server-three is associated with other-server-group and uses that group’s configurations. It also defines a port-offset value and sets auto-start to false so that this server does not start when the host controller starts.

Servers can be configured using the management CLI or from the management console Runtime tab.

Add a Server

The following management CLI command can be used to add a server.

/host=HOST_NAME/server-config=SERVER_NAME:add(group=SERVER_GROUP_NAME)

Update a Server

The following management CLI command can be used to update server attributes.

/host=HOST_NAME/server-config=SERVER_NAME:write-attribute(name=ATTRIBUTE_NAME,value=VALUE)

Remove a Server

The following management CLI command can be used to remove a server.

/host=HOST_NAME/server-config=SERVER_NAME:remove

Server Attributes

A server requires the following attributes:

A server includes the following optional attributes:

You can perform operations on servers, such as starting, stopping, and reloading, from the management console by navigating to the Runtime tab and selecting the appropriate host or server group.

See the below commands for performing these operations using the management CLI.

Start Servers

You can start a single server on a particular host.

/host=HOST_NAME/server-config=SERVER_NAME:start

You can start all servers in a specified server group.

/server-group=SERVER_GROUP_NAME:start-servers

Stop Servers

You can stop a single server on a particular host.

/host=HOST_NAME/server-config=SERVER_NAME:stop

You can stop all servers in a specified server group.

/server-group=SERVER_GROUP_NAME:stop-servers

Reload Servers

You can reload a single server on a particular host.

/host=HOST_NAME/server-config=SERVER_NAME:reload

You can reload all servers in a specified server group.

/server-group=SERVER_GROUP_NAME:reload-servers

You can run multiple host controllers on a single machine by using the jboss.domain.base.dir property.

Each instance started in this manner will share the rest of the resources in the base installation directory (for example, EAP_HOME/modules/), but use the domain configuration from the directory specified by jboss.domain.base.dir.

You can create managed domain on two machines, where one machine is a domain controller and the other machine is a host. For more information, see About the Domain Controller.

Create a Managed Domain on Two Machines

You can now manage the domain from the management CLI by specifying the domain controller address with the --controller parameter when launching.

$ EAP_HOME/bin/jboss-cli.sh --connect --controller=IP1

Or you can manage the domain from the management console at http://IP1:9990.

A JBoss EAP 7 domain controller can manage hosts and servers running older versions of JBoss EAP as long as the following conditions are met.

Complete the following tasks to successfully manage JBoss EAP 6 instances in a JBoss EAP 7 managed domain.

Once these tasks are complete, you can manage your JBoss EAP 6 servers and configurations from the JBoss EAP 7 domain controller using the management CLI. Note that JBoss EAP 6 hosts will not be able to take advantage of new JBoss EAP 7 features, such as batch processing.

<servers>
    <server name="server-one" group="eap6-main-server-group"/>
    <server name="server-two" group="eap6-main-server-group">
        <socket-bindings port-offset="150"/>
    </server>
</servers>

/host-exclude=EAP64z:write-attribute(name=active-server-groups,value=[eap6-main-server-group])

JBoss EAP uses profiles as a way to organize which subsystems are available to a server. A profile consists of a collection of available subsystems along with each subsystem’s specific configuration. A profile with a large number of subsystems results in a server with a large set of capabilities. A profile with a small, focused set of subsystems will have fewer capabilities but a smaller footprint.

JBoss EAP comes with four predefined profiles that should satisfy most use cases:

In cases where the existing profiles do not provide the necessary capabilities, JBoss EAP also provides the ability to define custom profiles as well.

JBoss EAP allows you to create a new profile in a managed domain by cloning an existing profile. This will create a copy of the original profile’s configuration and subsystems.

A profile can be cloned using the management CLI by using the clone operation on the desired profile to clone.

/profile=full-ha:clone(to-profile=cloned-profile)

You can also clone a profile from the management console by selecting the desired profile to clone and clicking Clone.

In a managed domain, you can create a hierarchy of profiles. This allows you to create a base profile with common extensions that other profiles can inherit.

The managed domain defines several profiles in domain.xml. If multiple profiles use the same configuration for a particular subsystem, you can configure it in just one place instead of different profiles. The values in parent profiles cannot be overridden.

A profile can include other profiles in a hierarchy using the management CLI by using the list-add operation and providing the profile to include.

/profile=new-profile:list-add(name=includes, value=PROFILE_NAME)

You can define JVM settings on a host controller, and apply those settings to server groups or individual servers. JBoss EAP comes with a default JVM setting, but the following management CLI command demonstrates creating a new JVM setting named production_jvm with some custom JVM settings and options.

/host=HOST_NAME/jvm=production_jvm:add(
    heap-size=2048m,
    max-heap-size=2048m,
    max-permgen-size=512m,
    stack-size=1024k,
    jvm-options=["-XX:-UseParallelGC"]
)

You can also create and edit JVM settings in the JBoss EAP management console by selecting the Runtime tab, selecting Hosts, and clicking JVM on the host you want to edit.

These settings are stored in the within the <jvm> tag in host.xml.

When creating a server group, you can specify a JVM configuration that all servers in the group will use. The following management CLI commands demonstrate creating a server group name groupA that uses the production_jvm JVM settings that were shown in the previous example.

/server-group=groupA:add(profile=default, socket-binding-group=standard-sockets)
/server-group=groupA/jvm=production_jvm:add()

All servers in the server group will inherit JVM settings from production_jvm.

You can also override specific JVM settings at the server group level. For example, to set a different heap size, you can use the following command:

/server-group=groupA/jvm=production_jvm:write-attribute(name=heap-size,value="1024m")

After applying the above command, the server group groupA will inherit the JVM settings from production_jvm, except for the heap size which has an overridden value of 1024m.

You can also edit server group JVM settings in the JBoss EAP management console by selecting the Runtime tab, selecting Server Groups, and clicking View for the server group you want to edit.

These settings for a server group are stored in domain.xml.

By default, an individual JBoss EAP server instance will inherit the JVM settings of the server group it belongs to. However, you can choose to override the inherited settings with another complete JVM setting definition from the host controller, or choose to override specific JVM settings.

For example, the following command overrides the JVM definition of the server group in the previous example, and sets the JVM settings for server-one to the default JVM definition:

/host=HOST_NAME/server-config=server-one/jvm=default:add()

Also, similar to server groups, you can override specific JVM settings at the server level. For example, to set a different heap size, you can use the following command:

/host=HOST_NAME/server-config=server-one/jvm=default:write-attribute(name=heap-size,value="1024m")

You can also edit server JVM settings in the JBoss EAP management console by selecting the Runtime tab, selecting Hosts, selecting the relevant host. Then select the relevant server, and click View for the server you want to edit.

These settings for an individual server are stored in host.xml.

By default, all JBoss EAP log entries are written to the server.log file. The location of this file depends on your operating mode.

This file is often referred to as the server log. For more information, see the Root Logger section.

During bootup, JBoss EAP logs information about the Java environment and the startup of each service. This log can be useful when troubleshooting. By default, all log entries are written to the server log.

Bootup logging configuration is specified in the logging.properties configuration file, which is active until the JBoss EAP logging subsystem is started and takes over. The location of this file depends on your operating mode.

Garbage collection logging logs all garbage collection activity to plain text log files. These log files can be useful for diagnostic purposes. Garbage collection logging is enabled by default for a JBoss EAP standalone server on all supported configurations except IBM Java development kit.

The location of the garbage collection log is EAP_HOME/standalone/log/gc.log.DIGIT.current. Garbage collection logs are limited to 3 MB each, and up to five files are rotated.

The following log files are created for the default logging configurations. The default configuration writes the server log files using periodic log handlers.

You can configure the default locale for JBoss EAP by setting JVM properties in the appropriate startup configuration file. The startup configuration file is EAP_HOME/bin/standalone.conf for a standalone server or EAP_HOME/bin/domain.conf for a managed domain.

Log messages that have been internationalized and localized will use this default locale. See the JBoss EAP Development Guide for information on creating internationalized log messages.

Set the Language

Specify the language by setting the user.language property using the JAVA_OPTS variable. For example, add the following line to the startup configuration file to set a French locale.

JAVA_OPTS="$JAVA_OPTS -Duser.language=fr"

Log messages that have been internationalized and localized will now output in French.

Set the Language and Country

In addition to the language, it may also be necessary to specify the country by setting the user.country property. For example, add the following line to the startup configuration file to set the Portuguese locale for Brazil.

JAVA_OPTS="$JAVA_OPTS -Duser.language=pt -Duser.country=BR"

Log messages that have been internationalized and localized will now output in Brazilian Portuguese.

Set the Server Locale Using the org.jboss.logging.locale Property

You can configure the org.jboss.logging.locale property to override the locale for messages logged using JBoss Logging, including any messages from JBoss EAP and its owned dependencies. Other dependencies, such as JSF, cannot get an overridden locale.

To start the JBoss EAP server with a different locale than the system default, you can edit EAP_HOME/bin/standalone.conf or the EAP_HOME/bin/domain.conf file, depending on your operating mode, and append the following command to set the JVM parameter for the required locale. The value of the property must be specified in the BCP 47 format. For example, to set Brazilian Portuguese, use pt-BR.

JAVA_OPTS="$JAVA_OPTS -Dorg.jboss.logging.locale=pt-BR"

The JBoss EAP root logger captures all log messages, of the specified log level or higher, sent to the server that are not captured by a log category.

By default, the root logger is configured to use a console and a periodic log handler. The periodic log handler is configured to write to the server.log file. This file is often referred to as the server log.

See Configuring the Root Logger for more information.

A log category defines a set of log messages to capture and one or more log handlers that will process the messages.

The log messages to capture are defined by the specified Java package of origin and log level. Messages from classes in that package and of that log level or higher are captured by the log category and sent to the specified log handlers.

Log categories can optionally use the log handlers of the root logger instead of their own handlers.

See Configuring Log Categories for more information.

Log handlers define how captured log messages are recorded. The available log handler types are console, file, periodic, size, periodic size, syslog, custom, and async.

Log Handler Types

For details on configuring each of these log handlers, see the Configuring Log Handlers section.

A log level is an enumerated value that indicates the nature and severity of a log message. As a developer, you can specify the level of a given log message using the appropriate method of your chosen logging framework to send the message.

JBoss EAP supports all the log levels used by the supported application logging frameworks. The most commonly used log levels from lowest to highest are TRACE, DEBUG, INFO, WARN, ERROR, and FATAL.

Log levels are used by log categories and handlers to limit the messages they are responsible for. Each log level has an assigned numeric value that indicates its order relative to other log levels. Log categories and handlers are assigned a log level, and they only process log messages of that level or higher. For example a log handler with the level of WARN will only record messages of the levels WARN, ERROR, and FATAL.

Supported Log Levels

A log formatter defines the appearance of log messages from that handler. It is a string that uses a syntax based on java.util.logging.Formatter class.

For example, the default configuration uses the following log formatter string for logging messages to the server log: %d{yyyy-MM-dd HH:mm:ss,SSS} %-5p [%c] (%t) %s%e%n. This will create log messages like the one shown below.

2016-03-18 15:49:32,075 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0051: Admin console listening on http://127.0.0.1:9990

For more information on configuring log formatters, see Configure a Named Pattern Formatter or Configure a Custom Log Formatter.

See the table below for the syntax used in log formatter strings.

Log Formatter Syntax

Filter expressions, configured using the filter-spec attribute, are used to record log messages based on various criteria. Filter checking is always done on a raw unformatted message. You can include a filter for a logger or handler, but the logger filter takes precedence over the filter put on a handler.

/subsystem=logging/console-handler=CONSOLE:write-attribute(name=filter-spec, value="substituteAll(\"WFLY\"\,\"YLFW\")")

By default, the JBoss EAP logging subsystem adds implicit logging API dependencies to deployments. You can control whether these implicit dependencies are added to deployments by using the add-logging-api-dependencies attribute, which is true by default.

Using the management CLI, you can set the add-logging-api-dependencies attribute to false so that the implicit logging API dependencies will not be added to deployments.

/subsystem=logging:write-attribute(name=add-logging-api-dependencies, value=false)

For information on the implicit dependencies for the logging subsystem, see the Implicit Module Dependencies section in the JBoss EAP Development Guide.

This section shows you how to configure a console log handler using the management CLI. You can also configure console log handlers using the management console by navigating to the Logging subsystem from the Configuration tab, selecting the Handler tab, and selecting Console from the left-hand menu.

The main tasks you will perform to configure a console log handler are:

Add a Console Log Handler

/subsystem=logging/console-handler=CONSOLE_HANDLER_NAME:add

Configure Console Log Handler Settings

Depending on your needs, you may need to set one or more of the following console log handler attributes. For a full list of available console log handler attributes and their descriptions, see Console Log Handler Attributes.

Assign the Console Log Handler to a Logger

In order for a log handler to be active, you must assign it to a logger.

The following management CLI command assigns the console log handler to the root logger.

/subsystem=logging/root-logger=ROOT:add-handler(name=CONSOLE_HANDLER_NAME)

The following management CLI command assigns the console log handler to a logger whose name is specified by CATEGORY.

/subsystem=logging/logger=CATEGORY:add-handler(name=CONSOLE_HANDLER_NAME)

Remove a Console Log Handler

A log handler can be removed with the remove operation. A log handler cannot be removed if it is currently assigned to a logger or async log handler.

/subsystem=logging/console-handler=CONSOLE_HANDLER_NAME:remove

This section shows you how to configure a file log handler using the management CLI. You can also configure file log handlers using the management console by navigating to the Logging subsystem from the Configuration tab, selecting the Handler tab, and selecting File from the left-hand menu.

The main tasks you will perform to configure a file log handler are:

Add a File Log Handler

When adding a file log handler, you must specify the file path using the file attribute, which is comprised of the path and relative-to attributes. Use the path attribute to set the file path for the log, including the name, for example my-log.log. Optionally, use the relative-to attribute to set that the path is relative to a named path, for example jboss.server.log.dir.

Per-deployment logging allows a developer to configure the logging configuration for their application in advance. When the application is deployed, logging begins according to the defined configuration. The log files created through this configuration contain information only about the behavior of the application.

This approach has advantages and disadvantages over using system-wide logging. An advantage is that the administrator of the JBoss EAP instance does not need to configure any other logging than the server logging. A disadvantage is that the per-deployment logging configuration is read only on server startup, and so cannot be changed at runtime.

For instructions on using per-deployment logging in your applications, see Add Per-deployment Logging to an Application in the JBoss EAP Development Guide.

Logging profiles are independent sets of logging configurations that can be assigned to deployed applications. As with the regular logging subsystem, a logging profile can define handlers, categories, and a root logger, but it cannot refer to configurations in other profiles or the main logging subsystem. The design of logging profiles mimics the logging subsystem for ease of configuration.

Logging profiles allow administrators to create logging configurations that are specific to one or more applications without affecting any other logging configurations. Because each profile is defined in the server configuration, the logging configuration can be changed without requiring that the affected applications be redeployed. However, logging profiles cannot be configured using the management console.

Each logging profile can have:

An application can specify a logging profile to use in its MANIFEST.MF file, using the Logging-Profile attribute.

/subsystem=logging/logging-profile=accounts-app-profile:add

/subsystem=logging/logging-profile=accounts-app-profile/file-handler=ejb-trace-file:add(file={path=>"ejb-trace.log", "relative-to"=>"jboss.server.log.dir"})

/subsystem=logging/logging-profile=accounts-app-profile/file-handler=ejb-trace-file:write-attribute(name="level", value="DEBUG")

/subsystem=logging/logging-profile=accounts-app-profile/logger=com.company.accounts.ejbs:add(level=TRACE)

/subsystem=logging/logging-profile=accounts-app-profile/logger=com.company.accounts.ejbs:add-handler(name="ejb-trace-file")

<logging-profiles>
   <logging-profile name="accounts-app-profile">
      <file-handler name="ejb-trace-file">
         <level name="DEBUG"/>
         <file relative-to="jboss.server.log.dir" path="ejb-trace.log"/>
      </file-handler>
      <logger category="com.company.accounts.ejbs">
         <level name="TRACE"/>
         <handlers>
            <handler name="ejb-trace-file"/>
         </handlers>

You can obtain information about the logging configuration for a particular deployment using the following management CLI command.

/deployment=DEPLOYMENT_NAME/subsystem=logging/configuration=CONFIG:read-resource

The logging configuration value (CONFIG) for a deployment can be one of three values:

For example, the below management CLI command displays the configuration for the MYPROFILE logging profile, which is used by the specified deployment.

/deployment=mydeployment.war/subsystem=logging/configuration=profile-MYPROFILE:read-resource(recursive=true,include-runtime=true)

This will output the following information.

{
    "outcome" => "success",
    "result" => {
        "error-manager" => undefined,
        "filter" => undefined,
        "formatter" => {

You could also use a recursive read-resource operation to read the logging configuration and other information about a deployment.

/deployment=DEPLOYMENT_NAME/subsystem=logging:read-resource(include-runtime=true, recursive=true)

JDBC drivers can be installed as a core module using the management CLI using the following steps.

The JDBC driver is now available to be referenced by application datasources.

JDBC drivers can be installed as a JAR deployment using either the management CLI or the management console. As long as the driver is JDBC 4-compliant, it will automatically be recognized and installed as a JDBC driver upon deployment.

The following steps describe how to install a JDBC driver using the management CLI.

The JDBC driver is now available to be referenced by application datasources.

Update a JDBC Driver JAR to be JDBC 4-Compliant

If the JDBC driver JAR is not JDBC 4-compliant, it can be made deployable using the following steps.

The following table gives the standard download locations for JDBC drivers of common databases used with JBoss EAP.

In some cases, it is necessary for an application to use vendor-specific functionality that is not part of the JDBC API. In these cases, you can access vendor-specific APIs by declaring a dependency in that application.

You can define a dependency for an application using either the MANIFEST.MF file or a jboss-deployment-structure.xml file.

If you have not yet done so, Install a JDBC Driver as a Core Module.

Using the MANIFEST.MF File

Using a jboss-deployment-structure.xml File

The example code below accesses the MySQL API.

import java.sql.Connection;
import org.jboss.jca.adapters.jdbc.WrappedConnection;

...

Connection c = ds.getConnection();
WrappedConnection wc = (WrappedConnection)c;
com.mysql.jdbc.Connection mc = wc.getUnderlyingConnection();

Non-XA datasources can be defined using the data-source add management CLI command. You can also define non-XA datasources using the management console by navigating to Configuration → Subsystems → Datasources → Non-XA and clicking Add to open the Create Datasource wizard.

The below steps describe how to define a non-XA datasource using the management CLI.

For detailed examples, see the Example Datasource Configurations for the supported databases.

Datasource Parameters

For a complete listing of all available datasource parameters, see the Datasource Parameters section.

XA datasources can be defined using the xa-data-source add management CLI command. You can also define XA datasources using the management console by navigating to Configuration → Subsystems → Datasources → XA and clicking Add to open the Create XA Datasource wizard.

The below steps describe how to define an XA datasource using the management CLI.

For detailed examples, see the Example Datasource Configurations for the supported databases.

Datasource Parameters

For a complete listing of all available datasource parameters, see the Datasource Parameters section.

Non-XA datasource settings can be updated using the data-source management CLI command. You can also update datasource attributes from the datasources subsystem in the management console.

Settings for a datasource can be updated by using the following management CLI command.

data-source --name=DATASOURCE_NAME --ATTRIBUTE_NAME=ATTRIBUTE_VALUE

A server reload may be required for the changes to take effect.

XA datasource settings can be updated using the xa-data-source management CLI command. You can also update datasource attributes from the datasources subsystem in the management console.

A server reload may be required for the changes to take effect.

Non-XA datasources can be removed using the data-source remove management CLI command. You can also remove datasources from the datasources subsystem in the management console.

data-source remove --name=DATASOURCE_NAME

The server will require a reload after the datasource is removed.

XA datasources can be removed using the xa-data-source remove management CLI command. You can also remove XA datasources from the datasources subsystem in the management console.

xa-data-source remove --name=XA_DATASOURCE_NAME

The server will require a reload after the XA datasource is removed.

For most JDBC resources, the recovery module is automatically associated with the resource. In these cases, you only need to configure the options that allow the recovery module to connect to your resource to perform recovery.

The following table describes the XA datasource parameters specific to XA recovery. Each of these configuration attributes can be set during datasource creation or afterward. You can set them using either the management console or the management CLI. See Modify an XA Datasource for information on configuring XA datasources.

Use the following management CLI command to disable recovery for an XA datasource:

/subsystem=datasources/xa-data-source=XA_DATASOURCE_NAME:write-attribute(name=no-recovery,value=true)

Vendor-Specific Configuration

Some databases require specific configurations in order to cooperate in XA transactions managed by the JBoss EAP transaction manager. For detailed and up-to-date information, see your database vendor’s documentation.

Known Issues

These known issues with handling XA transactions are for the specific database and JDBC driver versions supported with JBoss EAP 7. For up-to-date information on the supported databases, see JBoss EAP supported configurations.

Example Management CLI Commands

This example configuration can be achieved by using the following management CLI commands.

You can configure the transaction manager using the web-based management console or the command line management CLI.

Configuring the Transaction Manager Using the Management Console

The following steps explain how to configure the transaction manager using the web-based management console:

Configuring the Transaction Manager Using the Management CLI

Using the management CLI, you can configure the transaction manager using a series of commands. The commands all begin with /subsystem=transactions for a standalone server or /profile=default/subsystem=transactions/ for the default profile in a managed domain.

For a detailed listing of all the transaction manager configuration options, see the Transaction Manager Configuration Options for JBoss EAP.

This task shows you how to enable Java Transaction API (JTA) on your datasource.

Prerequisites

Configuring the Datasource to use Java Transaction API

Your datasource is now configured to use JTA.

You can track the transaction status while keeping the log files readable by using the DEBUG log level for the transaction logger. For detailed debugging, use the TRACE log level. Refer to Configuring Logging for the Transactions Subsystem for information on configuring the transaction logger.

Transaction Manager (TM) can generate a lot of logging information when configured to log in the TRACE log level. Following are some of the most commonly-seen messages. This list is not comprehensive, so you may see messages other than these.

You can control the amount of information logged about transactions, independent of other logging settings in JBoss EAP. You can configure the logging settings using the management console or the management CLI.

Configuring the Transaction Logger Using the Management Console

Configuring the Transaction Logger Using the Management CLI

Use the following command to set the logging level from the management CLI. For a standalone server, remove the /profile=default from the command.

/profile=default/subsystem=logging/logger=com.arjuna:write-attribute(name=level,value=VALUE)

The management CLI supports the ability to browse and manipulate transaction records. This functionality is provided by the interaction between the TM and the management API of JBoss EAP.

The TM stores information about each pending transaction and the participants involved the transaction, in a persistent storage called the object store. The management API exposes the object store as a resource called the log-store. The probe operation reads the transaction logs and creates a node path for each record. You can call the probe operation manually, whenever you need to refresh the log-store. It is normal for transaction logs to appear and disappear quickly.

Refresh the Log Store

The following command refreshes the log store for server groups which use the profile default in a managed domain. For a standalone server, remove the profile=default from the command.

/profile=default/subsystem=transactions/log-store=log-store:probe

View All Prepared Transactions

To view all prepared transactions, first refresh the log store (see Refresh the Log Store), then run the following command, which functions similarly to a file system ls command.

ls /profile=default/subsystem=transactions/log-store=log-store/transactions

Or

/host=master/server=server-one/subsystem=transactions/log-store=log-store:read-children-names(child-type=transactions)

Each transaction is shown, along with its unique identifier. Individual operations can be run against an individual transaction (see Manage a Transaction).
