Chapter 11. How to…​

The following CLI commands and operations provide basic examples on how to accomplish certain tasks. For detailed instructions, see the appropriate section of the Configuration Guide, Configuring Messaging, or other JBoss EAP documentation.

Unless specified otherwise, the examples apply when running as a standalone server. Use the --help argument on a command to get usage for that command. Use the read-operation-description to get information on a particular operation for a resource.

11.1. Add a Datasource

data-source add --name=DATASOURCE_NAME --jndi-name=JNDI_NAME --driver-name=DRIVER_NAME  --connection-url=CONNECTION_URL

11.2. Add an Extension

Example: Add a New Extension to a Configuration

/extension=EXTENSION_NAME:add

11.3. Add a JMS Queue

jms-queue add --queue-address=QUEUE_NAME --entries=JNDI_NAME

11.4. Add a JMS Topic

jms-topic add --topic-address=TOPIC_NAME --entries=JNDI_NAME

11.5. Add a Module

module add --name=MODULE_NAME --resources=PATH_TO_RESOURCE --dependencies=DEPENDENCIES
Important

Using the module management CLI command to add and remove modules is provided as Technology Preview only. This command is not appropriate for use in a managed domain or when connecting to the management CLI remotely. Modules should be added and removed manually in a production environment. For more information, see the Create a Custom Module Manually and Remove a Custom Module Manually sections of the JBoss EAP Configuration Guide.

Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend to use them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

See Technology Preview Features Support Scope on the Red Hat Customer Portal for information about the support scope for Technology Preview features.

11.6. Add a Server

Example: Add a New Server to a Host in a Managed Domain

/system-property=PROPERTY_NAME:add(value=PROPERTY_VALUE)

11.9. Clone a Profile

Example: Clone a Profile in a Managed Domain

/profile=PROFILE_TO_CLONE:clone(to-profile=NEW_PROFILE_NAME)

11.10. Create a Hierarchical Profile

Example: Create a New Profile That Inherits from Other Profiles

/profile=NEW_PROFILE_NAME:add(includes=[PROFILE_1,PROFILE_2])

11.11. Deploy an Application to a Managed Domain

Example: Deploy an Application to All Server Groups

:whoami

Example: Output for the Current User

{
    "outcome" => "success",
    "result" => {"identity" => {
        "username" => "$local",
        "realm" => "ManagementRealm"
    }}
}

11.15. Display the Contents of an Attachment

You can use the attachment display command to display the contents of an attachment returned from a management operation. This applies to any management operation that returns the attached-streams response header.

For example, the following operation returns the server.log file attached as a stream.

/subsystem=logging/log-file=server.log:read-attribute(name=stream)
{
    "outcome" => "success",
    "result" => "f61a27c4-c5a7-43ac-af1f-29e90c9acb3e",
    "response-headers" => {"attached-streams" => [{
        "uuid" => "f61a27c4-c5a7-43ac-af1f-29e90c9acb3e",
        "mime-type" => "text/plain"
    }]}
}

You can use the attachment display command to display the contents of the stream returned form this operation to the console.

attachment display --operation=/subsystem=logging/log-file=server.log:read-attribute(name=stream)

This outputs the contents of the server.log file to the console.

    "outcome" => "success",
    "result" => [{"summary" => {
        "host-name" => "HOST_NAME",
        "instance-identifier" => "INSTANCE_ID",
        "product-name" => "JBoss EAP",
        "product-version" => "7.2.0.GA",
        "product-community-identifier" => "Product",
        "product-home" => "EAP_HOME",
        "standalone-or-domain-identifier" => "OPERATING_MODE",
        "host-operating-system" => "OS_NAME",
        "host-cpu" => {
            "host-cpu-arch" => "CPU_ARCH",
            "host-core-count" => CORE_COUNT
        },
        "jvm" => {
            "name" => "JAVA_VM_NAME",
            "java-version" => "JAVA_VERSION",
            "jvm-version" => "JAVA_VM_VERSION",
            "jvm-vendor" => "JAVA_VM_VENDOR",
            "java-home" => "JAVA_HOME"
        }
    }}]
}

11.30. Save the Contents of an Attachment

You can use the attachment save command to save the contents of an attachment returned from a management operation to a file. This applies to any management operation that returns the attached-streams response header.

For example, the following operation returns the server.log file attached as a stream.

/subsystem=logging/log-file=server.log:read-attribute(name=stream)
{
    "outcome" => "success",
    "result" => "f61a27c4-c5a7-43ac-af1f-29e90c9acb3e",
    "response-headers" => {"attached-streams" => [{
        "uuid" => "f61a27c4-c5a7-43ac-af1f-29e90c9acb3e",
        "mime-type" => "text/plain"
    }]}
}

You can use the attachment save command to save the contents of the stream returned form this operation to a file.

attachment save --operation=/subsystem=logging/log-file=server.log:read-attribute(name=stream) --file=log-output.txt

This saves the contents of the server.log file to EAP_HOME/bin/log-output.txt.

reload --host=EXISTING_HOST_NAME

The host must be reloaded in order for the changes to take effect.

11.43. Upload an Attachment

You can upload a local file as an attachment to management operations that accept file streams. For example, the following management CLI command uses the input-stream-index option to upload the contents of a local file to an exploded deployment.

/deployment=DEPLOYMENT_NAME.war:add-content(content=[{target-path=/path/to/FILE_IN_DEPLOYMENT, input-stream-index=/path/to/LOCAL_FILE_TO_UPLOAD}]
