Abstract

This guide outlines introductory concepts and operations within Red Hat JBoss Data Grid 6.3.2

Part I. Introducing Red Hat JBoss Data Grid

Chapter 1. Red Hat JBoss Data Grid

Red Hat JBoss Data Grid is a distributed in-memory data grid, which provides the following capabilities:
  • Schemaless key-value store – JBoss Data Grid is a NoSQL database that provides the flexibility to store different objects without a fixed data model.
  • Grid-based data storage – JBoss Data Grid is designed to easily replicate data across multiple nodes.
  • Elastic scaling – Adding and removing nodes is simple and non-disruptive.
  • Multiple access protocols – It is easy to access the data grid using REST, Memcached, Hot Rod, or simple map-like API.

1.1. Supported Configurations

The set of supported features, configurations, and integrations for Red Hat JBoss Data Grid (current and past versions) are available at the Supported Configurations page at https://access.redhat.com/articles/115883.

1.2. Components and Versions

Red Hat JBoss Data Grid includes many components for Library and Remote Client-Server modes. A comprehensive (and up to date) list of components included in each of these usage modes and their versions is available in the Red Hat JBoss Data Grid Component Details page at https://access.redhat.com/articles/488833

1.3. Red Hat JBoss Data Grid Usage Modes

Red Hat JBoss Data Grid offers two usage modes:
  • Remote Client-Server mode
  • Library mode

1.3.1. Remote Client-Server Mode

Remote Client-Server mode provides a managed, distributed, and clusterable data grid server. Applications can remotely access the data grid server using Hot Rod, Memcached or REST client APIs.
All Red Hat JBoss Data Grid operations in Remote Client-Server mode are non-transactional. As a result, a number of features cannot be performed when running JBoss Data Grid in Remote Client-Server mode.
There are a number of benefits to running JBoss Data Grid in Remote Client-Server mode if Library mode features are not required. Remote Client-Server mode is client language agnostic, provided there is a client library for your chosen protocol. As a result, Remote Client-Server mode provides:
  • easier scaling of the data grid.
  • easier upgrades of the data grid without impact on client applications.
Run the following commands to start JBoss Data Grid in Remote Client-Server mode.
For Linux:
$JBOSS_HOME/bin/standalone.sh
For Windows:
$JBOSS_HOME\bin\standalone.bat

1.3.2. Library Mode

Library mode allows building and deploying a custom runtime environment. The Library mode hosts a single data grid node in the applications process, with remote access to nodes hosted in other JVMs. Tested containers for Red Hat JBoss Data Grid 6 Library mode includes Red Hat JBoss Enterprise Web Server 2.x and JBoss Enterprise Application Platform 6.x.
A number of features in JBoss Data Grid can be used in Library mode, but not Remote Client-Server mode.
The following features require Library mode:
  • transactions
  • listeners and notifications
JBoss Data Grid can also be run as a standalone application in Java SE. Standalone mode is a supported alternative to running JBoss Data Grid in a container.

1.4. Red Hat JBoss Data Grid Benefits

Red Hat JBoss Data Grid provides the following benefits:

Benefits of JBoss Data Grid

Performance
Accessing objects from local memory is faster than accessing objects from remote data stores (such as a database). JBoss Data Grid provides an efficient way to store in-memory objects coming from a slower data source, resulting in faster performance than a remote data store. JBoss Data Grid also offers optimization for both clustered and non clustered caches to further improve performance.
Consistency
Storing data in a cache carries the inherent risk: at the time it is accessed, the data may be outdated (stale). To address this risk, JBoss Data Grid uses mechanisms such as cache invalidation and expiration to remove stale data entries from the cache. Additionally, JBoss Data Grid supports JTA, distributed (XA) and two-phase commit transactions along with transaction recovery and a version API to remove or replace data according to saved versions.
Massive Heap and High Availability
In JBoss Data Grid, applications no longer need to delegate the majority of their data lookup processes to a large single server database for performance benefits. JBoss Data Grid employs techniques such as replication and distribution to completely remove the bottleneck that exists in the majority of current enterprise applications.

Example 1.1. Massive Heap and High Availability Example

In a sample grid with 16 blade servers, each node has 2 GB storage space dedicated for a replicated cache. In this case, all the data in the grid is copies of the 2 GB data. In contrast, using a distributed grid (assuming the requirement of one copy per data item, resulting in the capacity of the overall heap being divided by two) the resulting memory backed virtual heap contains 16 GB data. This data can now be effectively accessed from anywhere in the grid. In case of a server failure, the grid promptly creates new copies of the lost data and places them on operational servers in the grid.
Scalability
A significant benefit of a distributed data grid over a replicated clustered cache is that a data grid is scalable in terms of both capacity and performance. Add a node to JBoss Data Grid to increase throughput and capacity for the entire grid. JBoss Data Grid uses a consistent hashing algorithm that limits the impact of adding or removing a node to a subset of the nodes instead of every node in the grid.
Due to the even distribution of data in JBoss Data Grid, the only upper limit for the size of the grid is the group communication on the network. The network's group communication is minimal and restricted only to the discovery of new nodes. Nodes are permitted by all data access patterns to communicate directly via peer-to-peer connections, facilitating further improved scalability. JBoss Data Grid clusters can be scaled up or down in real time without requiring an infrastructure restart. The result of the real time application of changes in scaling policies results in an exceptionally flexible environment.
Data Distribution
JBoss Data Grid uses consistent hash algorithms to determine the locations for keys in clusters. Benefits associated with consistent hashing include:
  • cost effectiveness.
  • speed.
  • deterministic location of keys with no requirements for further metadata or network traffic.
Data distribution ensures that sufficient copies exist within the cluster to provide durability and fault tolerance, while not an abundance of copies, which would reduce the environment's scalability.
Persistence
JBoss Data Grid exposes a CacheStore interface and several high-performance implementations, including the JDBC Cache stores and file system based cache stores. Cache stores can be used to populate the cache when it starts and to ensure that the relevant data remains safe from corruption. The cache store also overflows data to the disk when required to prevent running out of memory.
Language bindings
JBoss Data Grid supports both the popular Memcached protocol, with existing clients for a large number of popular programming languages, as well as an optimized JBoss Data Grid specific protocol called Hot Rod. As a result, instead of being restricted to Java, JBoss Data Grid can be used for any major website or application. Additionally, remote caches can be accessed using the HTTP protocol via a RESTful API.
Management
In a grid environment of several hundred or more servers, management is an important feature. JBoss Operations Network, the enterprise network management software, is the best tool to manage multiple JBoss Data Grid instances. JBoss Operations Network's features allow easy and effective monitoring of the Cache Manager and cache instances.
Remote Data Grids
Rather than scale up the entire application server architecture to scale up your data grid, JBoss Data Grid provides a Remote Client-Server mode which allows the data grid infrastructure to be upgraded independently from the application server architecture. Additionally, the data grid server can be assigned different resources than the application server and also allow independent data grid upgrades and application redeployment within the data grid.

1.5. Red Hat JBoss Data Grid Version Information

Red Hat JBoss Data Grid is based on Infinispan, the open source community version of the data grid software. Infinispan uses code, designs, and ideas from JBoss Cache, which have been tried, tested, and proved in high stress environments. As a result, JBoss Data Grid's first release is version 6.0 as a result of its deployment history.
The following table lists the correlation between JBoss Data Grid and Infinispan versions.

Table 1.1. JBoss Data Grid and Infinispan Correlation

JBoss Data Grid Product Infinispan Version
JBoss Data Grid 6.0.0 Infinispan 5.1.5
JBoss Data Grid 6.0.1 Infinispan 5.1.7
JBoss Data Grid 6.1.0 Infinispan 5.2.4
JBoss Data Grid 6.2.0 Infinispan 6.0.1
JBoss Data Grid 6.3.0 Infinispan 6.1.0

Note

From Red Hat JBoss Data Grid 6.2.0 onwards, there is no direct corresponding version of Infinispan for each JBoss Data Grid release. The Infinispan version provided for JBoss Data Grid 6.3.0 and later are based on an internal version number (possibly an unreleased version) of Infinispan.

1.6. Red Hat JBoss Data Grid Cache Architecture

Red Hat JBoss Data Grid Cache Architecture Diagram

Figure 1.1. Red Hat JBoss Data Grid Cache Architecture

Red Hat JBoss Data Grid's cache infrastructure depicts the individual elements and their interaction with each other in each JBoss Data Grid Usage Mode (Library and Remote Client-Server). For clarity, each cache architecture diagram is separated into two parts:
  • Elements that a user cannot directly interact with are depicted within a dark grey box in the diagram. In Remote Client-Server mode, this includes Persistent Store, Cache, Cache Manager, L1 Cache, and Server Module. In Library mode, user cannot directly interact with Persistent Store and L1 Cache.
  • Elements that a user can interact directly with are depicted in a light grey box in the diagram. In Remote Client-Server mode, this includes the Application and the Cache Client. In Library mode, users are allowed to interact with the Cache and Cache Manager, as well as the Application.
Cache Architecture Elements

JBoss Data Grid's cache architecture includes the following elements:

  1. The Persistent Store is an optional component. It can permanently store the cached entries for restoration after a data grid shutdown.
  2. The Level 1 Cache (or L1 Cache) stores remote cache entries after they are initially accessed, preventing unnecessary remote fetch operations for each subsequent use of the same entries.
  3. The Cache Manager controls the life cycle of Cache instances and can store and retrieve them when required.
  4. The Cache is the main component for storage and retrieval of the key-value entries.
Library and Remote Client-Server Mode Architecture

In Library mode, the Application (user code) can interact with the Cache and Cache Manager components directly. In this case the Application resides in the same Java Virtual Machine (JVM) and can call Cache and Cache Manager Java API methods directly.

In Remote Client-Server mode, the Application does not directly interact with the cache. Additionally, the Application usually resides in a different JVM, on different physical host, or does not need to be a Java Application. In this case, the Application uses a Cache Client that communicates with a remote JBoss Data Grid Server over the network using one of the supported protocols such as Memcached, Hot Rod, or REST. The appropriate server module handles the communication on the server side. When a request is sent to the server remotely, it translates the protocol back to the concrete operations performed on the cache component to store and retrieve data.

1.7. Red Hat JBoss Data Grid APIs

Red Hat JBoss Data Grid provides the following programmable APIs:
  • Cache
  • Batching
  • Grouping
  • Persistence (formerly CacheStore)
  • ConfigurationBuilder
  • Externalizable
  • Notification (also known as the Listener API because it deals with Notifications and Listeners)
JBoss Data Grid offers the following APIs to interact with the data grid in Remote Client-Server mode:
  • The Asynchronous API (can only be used in conjunction with the Hot Rod Client in Remote Client-Server Mode)
  • The REST Interface
  • The Memcached Interface
  • The Hot Rod Interface
    • The RemoteCache API

Part II. Download and Install Red Hat JBoss Data Grid

Chapter 2. Download Red Hat JBoss Data Grid

2.1. Red Hat JBoss Data Grid Installation Prerequisites

The only prerequisite to set up Red Hat JBoss Data Grid is an installed Java Virtual Machine (compatible with Java 6.0 or later).

2.2. Java Virtual Machine

A Java Virtual Machine (JVM) is a virtual environment that runs and executes Java programs on a host operating system. The JVM acts as an abstract computer and is a platform-independent execution environment that converts the Java programming code into machine language. A Java Virtual Machine (JVM) makes Java portable by providing an abstraction layer between the compiled Java program and the underlying hardware platform and operating system.
Red Hat recommends using OpenJDK Java platform as it is an open source, supported Java Virtual Machine that runs well on Red Hat Enterprise Linux systems. For Windows users, Oracle JDK 1.6 installation is recommended.

2.3. Install OpenJDK on Red Hat Enterprise Linux

Procedure 2.1. Install OpenJDK on Red Hat Enterprise Linux

  1. Subscribe to the Base Channel

    Obtain the OpenJDK from the RHN base channel. Your installation of Red Hat Enterprise Linux is subscribed to this channel by default.
  2. Install the Package

    Use the yum utility to install OpenJDK:
    $ sudo yum install java-1.6.0-openjdk-devel
    
  3. Verify that OpenJDK is the System Default

    Ensure that the correct JDK is set as the system default as follows:
    1. Log in as a user with root privileges and run the alternatives command:
      $ /usr/sbin/alternatives --config java
    2. Depending on the OpenJDK version, select /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java.
    3. Use the following command to set javac:
      $ /usr/sbin/alternatives --config javac
    4. Depending on the OpenJDK version used, select /usr/lib/jvm/java-1.6.0-openjdk/bin/java or /usr/lib/jvm/java-1.7.0-openjdk/bin/java.

2.4. Download and Install JBoss Data Grid

Use the following steps to download and install Red Hat JBoss Data Grid:
  1. Download JBoss Data Grid from the Red Hat Customer Portal.
  2. Verify the downloaded files.
  3. Install JBoss Data Grid.

2.4.1. Download Red Hat JBoss Data Grid

Follow the listed steps to download Red Hat JBoss Data Grid from the Customer Portal:

Procedure 2.2. Download JBoss Data Grid

  1. Log into the Customer Portal at https://access.redhat.com.
  2. Click the Downloads button near the top of the page.
  3. In the Product Downloads page, click Red Hat JBoss Data Grid.
  4. Select the appropriate JBoss Data Grid version from the Version: drop down menu.
  5. Download the appropriate files from the list that displays.

2.4.2. About the Red Hat Customer Portal

The Red Hat Customer Portal is the centralized platform for Red Hat knowledge and subscription resources. Use the Red Hat Customer Portal to do the following:
  • Manage and maintain Red Hat entitlements and support contracts.
  • Download officially-supported software.
  • Access product documentation and the Red Hat Knowledgebase.
  • Contact Global Support Services.
  • File bugs against Red Hat products.
The Customer Portal is available here: https://access.redhat.com.

2.4.3. Checksum Validation

Checksum validation is used to ensure a downloaded file has not been corrupted. Checksum validation employs algorithms that compute a fixed-size datum (or checksum) from an arbitrary block of digital data. If two parties compute a checksum of a particular file using the same algorithm, the results will be identical. Therefore, when computing the checksum of a downloaded file using the same algorithm as the supplier, if the checksums match, the integrity of the file is confirmed. If there is a discrepancy, the file has been corrupted in the download process.

2.4.4. Verify the Downloaded File

Procedure 2.3. Verify the Downloaded File

  1. To verify that a file downloaded from the Red Hat Customer Portal is error-free, access the portal site and go to that package's Software Details page. The Software Details page displays the MD5 and SHA256 "checksum" values. Use the checksum values to check the integrity of the file.
  2. Open a terminal window and run either the md5sum or sha256sum command, with the downloaded file as an argument. The program displays the checksum value for the file as the output for the command.
  3. Compare the checksum value returned by the command to the corresponding value displayed on the Software Details page for the file.

    Note

    Microsoft Windows does not come equipped with a checksum tool. Windows operating system users have to download a third-party product instead.
Result

If the two checksum values are identical then the file has not been altered or corrupted and is, therefore, safe to use.

If the two checksum values are not identical, then download the file again. A difference between the checksum values means that the file has either been corrupted during download or has been modified since it was uploaded to the server. If, after several downloads, the checksum will still not successfully validate, contact Red Hat Support for assistance.

2.4.5. Install Red Hat JBoss Data Grid

Prerequisite

Locate the appropriate version, platform, and file type and download Red Hat JBoss Data Grid from the Customer Portal.

Procedure 2.4. Install JBoss Data Grid

  1. Copy the downloaded JBoss Data Grid package to the preferred location on your machine.
  2. Run the following command to extract the downloaded JBoss Data Grid package:
    $ unzip JDG_PACKAGE
    Replace JDG_PACKAGE with the name of the JBoss Data Grid usage mode package downloaded from the Red Hat Customer Portal.
  3. The resulting unzipped directory will now be referred to as $JDG_HOME.

2.4.6. Red Hat Documentation Site

Red Hat's official documentation site is available at https://access.redhat.com/site/documentation/. There you will find the latest version of every book, including this one.

Chapter 3. Install and Use the Maven Repositories

3.1. About Maven

Apache Maven is a distributed build automation tool used in Java application development to create, manage, and build software projects. Maven uses standard configuration files called Project Object Model (POM) files to define projects and manage the build process. POM files describe the module and component dependencies, build order, and targets for the resulting project packaging and output using an XML file. This ensures that the project is built correctly and in a uniform manner.

Important

Red Hat JBoss Data Grid requires Maven 3 (or better) for all quickstarts and general use.
Visit the Maven Download page (http://maven.apache.org/download.html) for instructions to download and install Maven.

3.2. Required Maven Repositories

Red Hat JBoss Data Grid Quickstarts require the following Maven repositories to be set up as a prerequisite:
Both Maven repositories are installed in the same way. As a result, the subsequent instructions are for both repositories.

3.3. Install the Maven Repository

There are three ways to install the required repositories:
  1. On Apache Web Server.
Use the option that best suits your environment.

3.3.1. Local File System Repository Installation

This option is best suited for initial testing in a small team. Follow the outlined procedure to extract the Red Hat JBoss Data Grid and JBoss Enterprise Application Platform Maven repositories to a directory in your local file system:

Procedure 3.1. Local File System Repository Installation (JBoss Data Grid)

  1. Log Into the Customer Portal

    In a browser window, navigate to the Customer Portal page (https://access.redhat.com/home) and log in.
  2. Download the JBoss Data Grid Repository File

    Download the jboss-datagrid-{VERSION}-maven-repository.zip file from the Red Hat Customer Portal.
  3. Unzip the file to a directory on your local file system (for example $JDG_HOME/projects/maven-repositories/).

3.3.2. Maven Repository Manager Installation

This option is ideal if you are already using a repository manager.
The Red Hat JBoss Data Grid and JBoss Enterprise Application Server repositories are installed using a Maven repository manager using its documentation. Examples of such repository managers are:

3.4. Configure the Maven Repository

To configure the installed Red Hat JBoss Data Grid Maven repository, edit the settings.xml file. The default version of this file is available in the conf directory of your Maven installation.
Maven user settings are located in the .m2 sub-directory of the user's home directory. See http://maven.apache.org/settings.html (the Maven documentation) for more information about configuring Maven.
See Section B.2, “Maven Repository Configuration Example” to view a sample Maven configuration.

3.4.1. Next Steps

After the newest available version of Red Hat JBoss Data Grid is installed and Maven is set up and configured, see Section 8.1, “Create a New Red Hat JBoss Data Grid Project” to learn how to use JBoss Data Grid for the first time.

Part III. Supported Containers for JBoss Data Grid

Chapter 4. Using JBoss Data Grid with Supported Containers

Red Hat JBoss Data Grid can be used in the following runtimes:
  • Java SE, started by your application.
  • As a standalone JBoss Data Grid server.
  • Bundled as a library in your application, deployed to an application server, and started by your application. For example, JBoss Data Grid can be used with Tomcat or Weblogic.
  • Inside an OSGi runtime environment, in this case, Apache Karaf.
For a list of containers supported with Red Hat JBoss Data Grid, see the Release Notes or the support information here: https://access.redhat.com/knowledge/articles/115883

4.1. Deploy JBoss Data Grid in JBoss EAP (Library Mode)

Red Hat JBoss Data Grid provides a set of modules for Red Hat JBoss Enterprise Application Platform 6.x. Using these modules means that JBoss Data Grid libraries do not need to be included in the user deployment. To avoid conflicts with the Infinispan modules that are already included with JBoss EAP, the JBoss Data Grid modules are placed within a separate slot and identified by the JBoss Data Grid version (major.minor).

Note

The JBoss EAP modules are not included in JBoss EAP. Instead, navigate to the Customer Support Portal at http://access.redhat.com to download these modules from the Red Hat JBoss Data Grid downloads page.
To deploy JBoss Data grid in JBoss EAP, add dependencies from the JBoss Data Grid module to the application's classpath (the JBoss EAP deployer) in one of the following ways:
  • Add a dependency to the jboss-deployment-structure.xml file.
  • Add a dependency to the MANIFEST.MF file.
  • Generate the MANIFEST.MF file via Maven.
Add a Dependency to the jboss-deployment-structure.xml File

Add the following configuration to the jboss-deployment-structure.xml file:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <deployment>
        <dependencies>
            <module name="org.infinispan" slot="jdg-6.3" services="export"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

Note

For details about the jboss-deployment-structure.xml file, see the Red Hat JBoss Enterprise Application Platform documentation.
Add a Dependency to the MANIFEST.MF File.

Add a dependency to the MANIFEST.MF files as follows:

Example 4.1. Example MANIFEST.MF File

Manifest-Version: 1.0
Dependencies: org.infinispan:jdg-6.3 services
The first line remains the same as the example. Depending on the dependency required, add one of the following to the second line of the file:
  • JBoss Data Grid Core:
    Dependencies: org.infinispan:jdg-6.3 services
  • Embedded Query:
    Dependencies: org.infinispan:jdg-6.3 services, org.infinispan.query:jdg-6.3 services
  • JDBC Cache Store:
    Dependencies: org.infinispan:jdg-6.3 services, org.infinispan.persistence.jdbc:jdg-6.3 services
  • JPA Cache Store:
    Dependencies: org.infinispan:jdg-6.3 services, org.infinispan.persistence.jpa:jdg-6.3 services
  • LevelDB Cache Store:
    Dependencies: org.infinispan:jdg-6.3 services, org.infinispan.persistence.leveldb:jdg-6.3 services
  • CDI:
    Dependencies: org.infinispan:jdg-6.3 services, org.infinispan.cdi:jdg-6.3 meta-inf
    
Generate the MANIFEST.MF file via Maven

The MANIFEST.MF file is generated during the build (specifically during the JAR or WAR process). As an alternative to adding a dependency to the MANIFEST.MF file, configure the dependency directly in Maven by adding the following to the pom.xml file:

<plugin>
	<artifactId>maven-war-plugin</artifactId>
	<version>2.4</version>
	<configuration>
		<failOnMissingWebXml>false</failOnMissingWebXml>
		<archive>
			<manifestEntries>
				<Dependencies>org.infinispan:jdg-6.3 services</Dependencies>
			</manifestEntries>
		</archive>
	</configuration>
</plugin>

    org.infinispan.commons:jdg-6.3 services, org.infinispan.client.hotrod:jdg-6.3 services, org.infinispan.query.dsl:jdg-6.3 services, org.jboss.remoting3

4.3. Deploy JBoss Data Grid in JBoss Enterprise Web Server

Red Hat JBoss Data Grid supports JBoss Enterprise Web Server in Library and Remote Client Server mode. To use JBoss Data Grid with JBoss Enterprise Web Server, bundle the JDG libraries in a web application and deploy the application on the server.

4.4. Deploy Web Applications on WebLogic Server (Library Mode)

Red Hat JBoss Data Grid supports the WebLogic 12c application server in Library mode. The following procedure describes how to deploy web applications on a WebLogic server.
Prerequisites

The prerequisites to deploy the web applications are as follows:

  1. WebLogic Server 12c.
  2. JBoss Data Grid Library (Embedded) mode.

Procedure 4.1. Deploying Web Applications on a WebLogic Server

  1. Create Web Applications

    Create a web application and add the libraries in the WEB-INF folder.
  2. Create a weblogic.xml Deployment Descriptor

    Create a weblogic.xml deployment descriptor with the following elements in it:
    <?xml version="1.0" encoding="UTF-8"?>
    <weblogic-web-app
            xmlns="http://www.bea.com/ns/weblogic/90"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">
        <container-descriptor>
            <prefer-web-inf-classes>true</prefer-web-inf-classes>
        </container-descriptor>
    </weblogic-web-app>

    Note

    The prefer-web-inf-classes class indicates that the libraries and the classes in the WEB-INF/lib folder is preferred over the default libraries bundled in the WebLogic server. For example, the commons-pool.jar file in the WebLogic server has version 1.4 and is automatically loaded by the classloader, but the Hot Rod client uses a newer version of this library.
  3. Pack the Web Application into a Web Archive File

    Create a web application archive (WAR) file of the web application and verify that the JBoss Data Grid libraries are in the WEB-INF folder along with the WebLogic deployment descriptor file.
  4. Deploy the Application onto WebLogic Server

    To deploy the web application using the Infinispan CDI module, stop the WebLogic server if it is running, apply the patch on it (Patch file p17424706_121200_Generic.zip) and restart the WebLogic server. If the Infinispan CDI module is not being used, deploy the web application normally.
    For more information about applying patch to the WebLogic Server, see the Oracle patch database on the Oracle website.

4.5. Deploy Web Applications on WebLogic Server (Remote Client-Server Mode)

Red Hat JBoss Data Grid supports the WebLogic 12c application server in Remote Client-Server mode. The following procedure describes how to deploy web applications on a WebLogic server.

Procedure 4.2. Deploying Web Applications on a WebLogic Server

  1. Configure JBoss Data Grid in Remote Client-Server mode, define cache, cache container, and endpoint configuration. After configuration, start JBoss Data Grid to confirm that the Hot Rod endpoint is listening on the configured port. For information about configuring JBoss Data Grid in Remote Client-Server, see Chapter 6, Run Red Hat JBoss Data Grid in Remote Client-Server Mode.
  2. Create a web application and add the infinispan-client-hotrod library as a dependency if Maven is used.
  3. Create a weblogic.xml deployment descriptor with the following elements in it:
    <?xml version="1.0" encoding="UTF-8"?>
    <weblogic-web-app
            xmlns="http://www.bea.com/ns/weblogic/90"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">
        <container-descriptor>
            <prefer-web-inf-classes>true</prefer-web-inf-classes>
        </container-descriptor>
    </weblogic-web-app>

    Note

    The prefer-web-inf-classes class indicates that the libraries and classes in the WEB-INF/lib folder are preferred over the default libraries bundled in the WebLogic server. For example, the commons-pool.jar file in the WebLogic server has version 1.4 and is automatically loaded by the classloader, however the Hot Rod client uses a newer version of this library.
  4. Add deployment descriptor file in the WEB-INF folder.
  5. Ensure that the infinispan-client-hotrod dependency is added to the pom.xml file, then use a Maven plugin to create a web archive. These dependencies ensure that the required libraries (infinispan-commons, infinispan-client-hotrod, commons-pool, jboss-logging, and jboss-marshalling-osgi) are included.
    Alternatively, create the web archive manually and add all the required libraries.
  6. Deploy the application in the WebLogic server and verify that the Hot Rod client embedded inside the web application connects to the remote JBoss Data Grid server.

4.6. Running Red Hat JBoss Data Grid in Karaf (OSGi)

Apache Karaf is a powerful, lightweight OSGi-based runtime container into which components and applications are deployed. OSGi implements a dynamic component model that does not exist in standalone JVM environments. OSGi containers such as Karaf include a rich set of tools for managing the life cycle of an application.
All dependencies between individual modules, including version numbers, must be explicitly specified. Where more than one class of the same name exists, the strict rules of OSGi specify which of the classes will be used by your bundle.

4.6.1. Running a Deployment of JBoss Data Grid in Karaf (Remote Client-Server)

The Red Hat JBoss Data Grid Hot Rod client can be run in an in an OSGi-based container such as Karaf.
Use the path in the JBoss Data Grid Maven repository to set up Karaf. Additionally, JBoss Data Grid requires a features file, located in org/infinispan/infinispan-client-hotrod/${VERSION}. This file lists all dependencies for the Hot Rod client in OSGi, while also making it simpler to install the feature into Karaf (version 2.3.3 or 3.0).

4.6.2. Installing the Hot Rod client feature in Karaf

Red Hat JBoss Data Grid's Hot Rod feature is installed in Karaf as follows:
Prerequisite

Configure the Red Hat JBoss Data Grid Maven Repository.

Procedure 4.3. Install the Hot Rod Feature in Karaf

  1. Karaf 2.3.3

    For Karaf 2.3.3 use the following commands:
    1. karaf@root> features:addUrl mvn:org.infinispan/infinispan-client-hotrod/${VERSION}/xml/features
    2. karaf@root> features:install hotrod-client
    3. Verify that the feature was successfully installed as follows:
      karaf@root> features:list
       //output
  2. Karaf 3.0.0

    For Karaf use the following commands.
    1. karaf@root> feature:repo-add mvn:org.infinispan/infinispan-client-hotrod/${VERSION}/xml/features
    2. karaf@root> feature:install hotrod-client
    3. Verify that the feature was successfully installed:
      karaf@root> feature:list
    Alternatively, use the -i command parameter to install the Hot Rod Client feature using the following:
    karaf@root()> feature:repo-add -i mvn:org.infinispan/infinispan-client-hotrod/${VERSION}/xml/features

4.6.3. Installing Red Hat JBoss Data Grid in Karaf (Library Mode)

The Red Hat JBoss Data Grid JAR files contain the required OSGi manifest headers and are used inside OSGi runtime environments as OSGi bundles. Additionally, the required third-party dependencies must be installed. These can be installed individually, or altogether via the features file, which defines all required dependencies.
To install bundles using the features file:
  • Register the feature repositories inside Karaf.
  • Install the features contained in the repositories.

Procedure 4.4. Installing bundles using the features file

  1. Start the Karaf console

    Start the Karaf console using the following commands:
    $ cd $APACHE_KARAF_HOME/bin
    $ ./karaf
  2. Register a feature repository

    Register a feature repository as follows:
    • For Karaf 2.3.3:
      karaf@root()> features:addUrl mvn:org.infinispan/infinispan-core/${VERSION}/xml/features
    • For Karaf 3.0.0:
      karaf@root()> feature:repo-add mvn:org.infinispan/infinispan-core/${VERSION}/xml/features
  3. List and Install the Available Features (Karaf 3.0.0)

    1. Get the list of available features using the following:
      karaf@root()> features:list
    2. Install the available features.
      karaf@root()> features:install
    Alternatively, pass the -i command parameter to the feature:repo-add command. This installs all the features defined in that repository. For example:
    karaf@root()> feature:repo-add -i mvn:org.infinispan/infinispan-core/${VERSION}/xml/features
Result

JBoss Data Grid runs in library mode using Karaf.

For additional functionality, install the corresponding features. For example, to use the LevelDB CacheStore, install the features as follows:
karaf@root()> feature:repo-add -i mvn:org.infinispan/infinispan-cachestore-leveldb/${VERSION}/xml/features
The URL for feature repositories is constructed from the Maven artifact coordinates using the following format:
mvn:<groupId>/<artifactId>/<version>/xml/features

4.6.4. Feature Repositories

Feature repositories for Red Hat JBoss Data Grid are available for the following artifacts:
  • infinispan-commons
  • infinispan-core
  • infinispan-cachestore-jdbc
  • infinispan-cachestore-leveldb
  • infinispan-cachestore-remote
  • infinispan-client-hotrod

Important

The JPA Cache Store is not supported in Apache Karaf in JBoss Data Grid 6.3.

Important

Querying in Library mode (which is covered in the Infinispan Query Guide) is not supported in Apache Karaf in JBoss Data Grid 6.3.

Chapter 6. Run Red Hat JBoss Data Grid in Remote Client-Server Mode

6.1. Prerequisites

The following is a list of prerequisites to run Red Hat JBoss Data Grid in Remote Client-Server mode for the first time:

6.2. Run Red Hat JBoss Data Grid in Standalone Mode

Standalone mode refers to a single instance of Red Hat JBoss Data Grid operating in local mode. In local mode, JBoss Data Grid operates as a simple single node in-memory data cache.
Run the following script to start JBoss Data Grid in standalone mode:
$JDG_HOME/bin/standalone.sh
This command starts JBoss Data Grid using the default configuration information provided in the $JDG_HOME/standalone/configuration/standalone.xml file.

6.3. Run Red Hat JBoss Data Grid in Clustered Mode

Clustered mode refers to a cluster made up of two or more Red Hat JBoss Data Grid instances.
Run the following script to start JBoss Data Grid in clustered mode:
$JDG_HOME/bin/clustered.sh
This command starts JBoss Data Grid using the default configuration information provided in the $JDG_HOME/standalone/configuration/clustered.xml file.

6.4. Run Red Hat JBoss Data Grid with a Custom Configuration

To run Red Hat JBoss Data Grid with a custom configuration, add a configuration file to the $JDG_HOME/standalone/configuration directory.
Use the following command to specify the created custom configuration file for standalone mode:
$JDG_HOME/bin/standalone.sh -c ${FILENAME}
Use the following command to specify the created custom configuration file for clustered mode:
$JDG_HOME/bin/clustered.sh -c ${FILENAME}
The -c used for this script does not allow absolute paths, therefore the specified file must be available in the $JDG_HOME/standalone/configuration directory.
If the command is run without the -c parameter, JBoss Data Grid uses the default configuration.

6.5. Set an IP Address to Run Red Hat JBoss Data Grid

For production use, the Red Hat JBoss Data Grid server must be bound to a specified IP address rather than to 127.0.0.1/localhost. Use the -b parameter with the script to specify an IP address.
For standalone mode, set the IP address as follows:
$JDG_HOME/bin/standalone.sh -b ${IP_ADDRESS}
For clustered mode, set the IP address as follows:
$JDG_HOME/bin/clustered.sh -b ${IP_ADDRESS}

6.6. Running Red Hat JBoss Data Grid

JBoss Data Grid can be run in one of three ways:
  • Use the following command to run JBoss Data Grid using the configuration defined in the standalone.xml file (located at $JDG_HOME/standalone/configuration):
    $JDG_HOME/bin/standalone.sh
  • Use the following command with an appended -c followed by the configuration file name to run JBoss Data Grid with a non-default configuration file:
    $JDG_HOME/bin/standalone.sh -c clustered.xml
  • Use the following command to run JBoss Data Grid with a default clustered configuration:
    $JDG_HOME/bin/clustered.sh

Chapter 7. Run a Red Hat JBoss Data Grid as a Node without Endpoints

Services send messages using channels to communicate with each other. An endpoint is a communications point for these services and is used to send and receive the messages sent through the channels. As a result, a node with no endpoints can communicate with other nodes in the same cluster, but not with clients.

7.1. Benefits of a Node Without Endpoints

The primary benefit for creating a node without endpoints in Red Hat JBoss Data Grid involves data replication.
A node without any endpoints cannot be accessed by the client directly. As a result, they are primarily used to replicate data from other nodes that can communicate with clients. The result is a node with a backup copy of the data that cannot be accessed by the client, which protects it from failure via an error sent by the client.

7.2. Sample Configuration for a Node without Endpoints

Red Hat JBoss Data Grid provides a sample configuration to configure a node without an endpoint:

Procedure 7.1. Find the JBoss Data Grid Sample Configuration for a Node Without Endpoints

  1. Extract the JBoss Data Grid ZIP

    1. Extract the ZIP file for JBoss Data Grid Remote Client-Server mode. This is named jboss-datagrid-server-${version}. Add the relevant version to the file name.
  2. Navigate to the Appropriate Folder

    In the extracted folder, navigate to the $JDG_HOME/docs/examples/config folder.
  3. Find the Configuration Sample File

    View the clustered-storage-only.xml file, which contains the configuration for a node with no endpoints.

7.3. Configure a Node with No Endpoints

A standard configuration, such as a standalone high availability configuration, can be changed into a configuration for a node with no endpoints using the following steps:
  1. Remove the datagrid subsystem.
  2. Remove the modcluster subsystem.
  3. Remove the datasource definition.
  4. Remove socket-bindings for mod_cluster, Hot Rod and memcached.
Removing the listed items ensure that all endpoints are removed from the configuration and that clustering is not possible. The resulting configuration is a node with no endpoints.

Chapter 8. Run Red Hat JBoss Data Grid in Library Mode

This part includes information about using Red Hat JBoss Data Grid in Library Mode.

8.1. Create a New Red Hat JBoss Data Grid Project

This chapter is a guide to creating a new Red Hat JBoss Data Grid project. The tasks prescribed are a prerequisite for the quickstart tasks provided in Chapter 9, Run Red Hat JBoss Data Grid in Library Mode (Single-Node Setup) and Chapter 10, Run Red Hat JBoss Data Grid in Library Mode (Multi-Node Setup)

8.2. Add Dependencies to Your Project

Set up Red Hat JBoss Data Grid by adding dependencies to your project. If you are using Maven or other build systems that support Maven dependencies, add the following to your pom.xml file, located in the Maven repository folder:
<dependency>
          <groupId>org.infinispan</groupId>
          <artifactId>infinispan-core</artifactId>
          <version>$VERSION</version>
</dependency>

Note

Replace the version value with the appropriate version of the libraries included in JBoss Data Grid.

8.3. Add a Profile to Your Project

To enable the JBoss Maven repository for your project, add a profile to your settings.xml file in $HOME/.m2/settings.xml as follows:

Example 8.1. Adding a Profile

<profiles>

    <!-- Configure the JBoss GA Maven repository -->
    <profile>
      <id>jboss-ga-repository</id>
      <repositories>
        <repository>
          <id>jboss-ga-repository</id>
          <url>http://maven.repository.redhat.com/techpreview/all</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>jboss-ga-plugin-repository</id>
          <url>http://maven.repository.redhat.com/techpreview/all</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </pluginRepository>
      </pluginRepositories>
    </profile>
    <!-- Configure the JBoss Early Access Maven repository -->
    <profile>
      <id>jboss-earlyaccess-repository</id>
      <repositories>
        <repository>
          <id>jboss-earlyaccess-repository</id>
          <url>http://maven.repository.redhat.com/earlyaccess/all/</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>jboss-earlyaccess-plugin-repository</id>
          <url>http://maven.repository.redhat.com/earlyaccess/all/</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </pluginRepository>
      </pluginRepositories>
    </profile>

  </profiles>

<!-- Add active profiles information here -->
Enable the profile by ensuring the following is included in the settings.xml file:

Example 8.2. Enable the Profile

  <activeProfiles>
    <!-- Optionally, make the repositories active by default -->
    <activeProfile>jboss-ga-repository</activeProfile>
    <activeProfile>jboss-earlyaccess-repository</activeProfile>
  </activeProfiles>
If you are using a build system that does not support declarative dependency management, add the contents of the client/java/ directory, included in the Red Hat JBoss Data Grid package to the build classpath.

Chapter 9. Run Red Hat JBoss Data Grid in Library Mode (Single-Node Setup)

9.1. Create a Main Method in the Quickstart Class

Create a new Quickstart class by following the outlined steps:
Prerequisites

These quickstarts use the Infinispan quickstarts located at https://github.com/infinispan/infinispan-quickstart. The following procedure uses the infinispan-quickstart/embedded-cache quickstart.

Procedure 9.1. Create a Main Method in the Quickstart Class

  1. Create the Quickstart.java File

    Create a file called Quickstart.java at your project's location.
  2. Add the Quickstart Class

    Add the following class and method to the Quickstart.java file:
    package com.mycompany.app;
    
    import org.infinispan.manager.DefaultCacheManager
    import org.infinispan.Cache
    
    public class Quickstart {
      public static void main(String args[]) throws Exception {
           Cache<Object, Object> cache = new DefaultCacheManager().getCache();
        }
     }
  3. Copy Dependencies and Compile Java Classes

    Use the following command to copy all project dependencies to a directory and compile the Java classes from your project:
    $ mvn clean compile dependency:copy-dependencies -DstripVersion
  4. Run the Main Method

    Use the following command to run the main method:
    $ java -cp target/classes/:target/dependency/* com.mycompany.app.Quickstart

9.2. Use the Default Cache

9.2.1. Add and Remove Data from the Cache

Red Hat JBoss Data Grid offers an interface that is similar to the proposed JSR-107 API to access and alter data stored in a cache.
The following procedure is an example that defines what each line entered into the DefaultCacheQuickstart.java file does:

Procedure 9.2. Add and Remove Data from the Cache

  1. Add an entry, replacing key and value with the desired key and value:
    cache.put("key", "value");
  2. Confirm that the entry is present in the cache:
    assertEquals(1, cache.size());
    assertTrue(cache.containsKey("key"));
  3. Remove the entry from the cache:
    Object v = cache.remove("key");
  4. Confirm that the entry is no longer present in the cache:
    assertEquals("value", v);
    assertTrue(cache.isEmpty());

9.2.2. Adding and Replacing a Key Value

Red Hat JBoss Data Grid offers a thread-safe data structure.
The following procedure is an example that defines what each line entered into the DefaultCacheQuickstart.java file does:

Procedure 9.3. Adding and Replacing a Key Value

  • Add an entry key with value as the key's value.
    cache.put("key", "value");

Procedure 9.4. Replacing a Key Value

  1. The following code searches for keys (named key and key2). If the two specific keys beings searched for are not found, JBoss Data Grid creates two new keys with the specified key names and values.
    cache.putIfAbsent("key", "newValue");
    cache.putIfAbsent("key2", "value2");
  2. The following code confirms that the value of the stored key equals the value we wanted to store.
    assertEquals(cache.get("key"), "value");
    assertEquals(cache.get("key2"), "value2");

9.2.3. Adjust Data Life

Red Hat JBoss Data Grid entries are immortal by default, but these settings can be altered.
The following procedure is an example that defines what each line entered into the DefaultCacheQuickstart.java file does:

Procedure 9.5. Adjust the Data Life

  1. Alter the key's lifespan value:
    cache.put("key", "value", 5, TimeUnit.SECONDS);
  2. Check if the cache contains the key:
    assertTrue(cache.containsKey("key"));
  3. After the allocated lifespan time has expired, the key is no longer in the cache:
    Thread.sleep(10000);
    assertFalse(cache.containsKey("key"));

9.2.4. Default Data Mortality

As a default, newly created entries do not have a life span or maximum idle time value set. Without these two values, a data entry will never expire and is therefore known as immortal data.

9.2.5. Register the Named Cache Using XML

To configure the named cache declaratively (using XML) rather than programmatically, configure the infinispan.xml file.
The infinispan.xml file is located in https://github.com/infinispan/infinispan-quickstart in the infinispan-quickstart/embedded-cache/src/main/resources folder.

Chapter 10. Run Red Hat JBoss Data Grid in Library Mode (Multi-Node Setup)

10.1. Sharing JGroup Channels

Red Hat JBoss Data Grid offers an easy to use form of clustering using JGroups as the network transport. As a result, JGroups manages the initial operations required to form a cluster for JBoss Data Grid.
All caches created from a single CacheManager share the same JGroups channel by default. This JGroups channel is used to multiplex replication/distribution messages.
In the following example, all three caches used the same JGroups channel:

Example 10.1. Shared JGroups Channel

EmbeddedCacheManager cm = $LOCATION
Cache<Object, Object> cache1 = cm.getCache("replSyncCache");
Cache<Object, Object> cache2 = cm.getCache("replAsyncCache");
Cache<Object, Object> cache3 = cm.getCache("invalidationSyncCache");
Substitute $LOCATION with the CacheManager's location.

10.2. Run Red Hat JBoss Data Grid in a Cluster

The clustered quickstarts for Red Hat JBoss Data Grid are based on the quickstarts found in https://github.com/infinispan/infinispan-quickstart/tree/master/clustered-cache.

10.2.1. Compile the Project

Use Maven to compile your project with the following command:
$ mvn clean compile dependency:copy-dependencies -DstripVersion

10.2.2. Run the Clustered Cache with Replication Mode

To run Red Hat JBoss Data Grid's replication mode example of a clustered cache, launch two nodes from different consoles.

Procedure 10.1. Run the Clustered Cache with Replication Mode

  1. Use the following command to launch the first node:
    $ java -cp target/classes/:target/dependency/* org.infinispan.quickstart.clusteredcache.replication.Node0
  2. Use the following command to launch the second node:
    $ java -cp target/classes/:target/dependency/* org.infinispan.quickstart.clusteredcache.replication.Node1
Result

JGroups and JBoss Data Grid initialized on both nodes. After approximately fifteen seconds, the cache entry log message appears on the console of the first node.

10.2.3. Run the Clustered Cache with Distribution Mode

To run Red Hat JBoss Data Grid's distribution mode example of a clustered cache, launch three nodes from different consoles.

Procedure 10.2. Run the Clustered Cache with Distribution Mode

  1. Use the following command to launch the first node:
    $ java -cp target/classes/:target/dependency/* org.infinispan.quickstart.clusteredcache.distribution.Node0
  2. Use the following command to launch the second node:
    $ java -cp target/classes/:target/dependency/* org.infinispan.quickstart.clusteredcache.distribution.Node1
  3. Use the following command to launch the third node:
    $ java -cp target/classes/:target/dependency/* org.infinispan.quickstart.clusteredcache.distribution.Node2
Result

JGroups and JBoss Data Grid initialized on the three nodes. After approximately fifteen seconds, the ten entries added by the third node are visible as they are distributed to the first and second nodes.

10.2.4. Configure the Cluster

Use the following steps to add and configure your cluster:

Procedure 10.3. Configure the Cluster

  1. Add the default configuration for a new cluster.
  2. Customize the default cluster configuration according to the requirements of your network. This is done declaratively (using XML) or programmatically.
  3. Configure the replicated or distributed data grid.

10.2.4.1. Add the Default Cluster Configuration

Add a cluster configuration to ensure that Red Hat JBoss Data Grid is aware that a cluster exists and is defined. The following is a default configuration that serves this purpose:

Example 10.2. Default Configuration

new ConfigurationBuilder()
   .clustering().cacheMode(CacheMode.REPL_SYNC)
   .build()

Note

Use the new GlobalConfigurationBuilder().clusteredDefault() to quickly create a preconfigured and cluster-aware GlobalConfiguration for clusters. This configuration can also be customized.

10.2.4.2. Customize the Default Cluster Configuration

Depending on the network requirements, you may need to customize your JGroups configuration.
Programmatic Configuration:

Use the following GlobalConfiguration code to specify the name of the file to use for JGroups configuration:

new GlobalConfigurationBuilder().transport().addProperty("configurationFile", "jgroups.xml")
   .build()
Replace jgroups.xml with the desired file name.
The jgroups.xml file is located at Infinispan-Quickstart/clustered-cache/src/main/resources/.

Note

To bind JGroups solely to your loopback interface (to avoid any configured firewalls), use the system property -Djgroups.bind_addr="127.0.0.1". This is particularly useful to test a cluster where all nodes are on a single machine.
Declarative Configuration:

Use the following XML snippet in the infinispan.xml file to configure the JGroups properties to use Red Hat JBoss Data Grid's XML configuration:

<global>
   <transport>
      <properties>
         <property name="configurationFile" value="jgroups.xml"/>
      </properties>
   </transport>
</global>

10.2.4.3. Configure the Replicated Data Grid

Red Hat JBoss Data Grid's replicated mode ensures that every entry is replicated on every node in the data grid.
This mode offers security against data loss due to node failures and excellent data availability. These benefits are at the cost of limiting the storage capacity to the amount of storage available on the node with the least memory.
Programmatic Configuration:

Use the following code snippet to programmatically configure the cache for replication mode (either synchronous or asynchronous):

private static EmbeddedCacheManager createCacheManagerProgramatically() {
   return new DefaultCacheManager(
      new GlobalConfigurationBuilder()
         .transport().addProperty("configurationFile", "jgroups.xml")
         .build(),
      new ConfigurationBuilder()
         .clustering().cacheMode(CacheMode.REPL_SYNC)
         .build()
   );
}
Declarative Configuration:

Edit the infinispan.xml file to include the following XML code to declaratively configure the cache for replication mode (either synchronous or asynchronous):

<infinispan xsi:schemaLocation="urn:infinispan:config:6.0 http://www.infinispan.org/schemas/infinispan-config-6.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:infinispan:config:6.0">
   <global>
      <transport>
         <properties>
            <property name="configurationFile" value="jgroups.xml"/>
         </properties>
      </transport>
   </global>
   <default>
      <clustering mode="replication">
         <sync/>
      </clustering>
   </default>
</infinispan>
Use the following code to initialize and return a DefaultCacheManager with the XML configuration file:
private static EmbeddedCacheManager createCacheManagerFromXml() throws IOException {
   return new DefaultCacheManager("infinispan.xml");}

Note

JBoss EAP includes its own underlying JMX. This can cause a collision when using the sample code with JBoss EAP and display an error such as org.infinispan.jmx.JmxDomainConflictException: Domain already registered org.infinispan.
To avoid this, configure global configuration as follows:
GlobalConfiguration glob = new GlobalConfigurationBuilder()
	.clusteredDefault()
        .globalJmxStatistics()
          .allowDuplicateDomains(true)
          .enable()
        .build();

10.2.4.4. Configure the Distributed Data Grid

Red Hat JBoss Data Grid's distributed mode ensures that each entry is stored on a subset of the total nodes in the data grid. The number of nodes in the subset is controlled by the numOwners parameter, which sets how many owners each entry has.
Distributed mode offers increased storage capacity but also results in increased access times and less durability (protection against node failures). Adjust the numOwners value to set the desired trade off between space, durability and availability. Durability is further improved by JBoss Data Grid's topology aware consistent hash, which locates entry owners across a variety of data centers, racks and nodes.
Programmatic Configuration:

Programmatically configure the cache for distributed mode (either synchronous or asynchronous) as follows:

new ConfigurationBuilder()
   .clustering()
      .cacheMode(CacheMode.DIST_SYNC)
      .hash().numOwners(2)
   .build()
Declarative Configuration:

Edit the cfg.xml file to include the following XML code to declaratively configure the cache for distributed mode (either synchronous or asynchronous):

<default>
   <clustering mode="distribution">
      <sync/>
      <hash numOwners="2"/>
   </clustering>
</default>

Chapter 11. Monitor Red Hat JBoss Data Grid Applications in Red Hat JBoss EAP

Red Hat JBoss Data Grid library applications (in the form of WAR or EAR files) can be deployed within JBoss Enterprise Application Server 6 (or better) and then monitored using JBoss Operations Network.

11.1. Prerequisites

The following are prerequisites to monitor a Red Hat JBoss Data Grid library application in JBoss Enterprise Application Platform:
  • Install and configure JBoss Enterprise Application Platform 6 (or better).
  • Install and configure JBoss Operations Network 3.2.2 (or better).
  • Install and configure JBoss Data Grid (6.3 or better) Library mode plug-in.

11.2. Monitor Red Hat JBoss Data Grid Applications in Red Hat JBoss EAP

Ensure that all requirements outlined as prerequisites are met. Follow the listed steps to monitor Red Hat JBoss Data Grid applications in JBoss Enterprise Application Platform using JBoss Operations Network or RHQ.

Procedure 11.1. Monitor JBoss Data Grid Applications in JBoss Enterprise Application Platform

  1. Configure RHQ/JBoss Operations Network

    Add an RHQ/JBoss Operations Network specific property (named org.rhq.resourceKey) to the /bin/standalone.conf file as follows:
    JAVA_OPTS="$JAVA_OPTS -Dorg.rhq.resourceKey=MyEAP"
    This command adds the property to the JBoss Enterprise Application Platform's command line indirectly.
  2. Check RHQ/JBoss Operations Network is Running Using a Full JDK

    Ensure that the RHQ/JBoss Operations Network agent started using a full JDK instead of a JRE. This is because the agent requires access to the JDK's tools.jar file.
    To configure your RHQ/JBoss Operations Network agent to use the JDK, follow the instructions relevant to your operating system:
    1. For Linux users, set the RHQ_AGENT_JAVA_HOME environment variable to the JDK home directory in the agent's rhq-agent-env.sh file.
    2. For Windows users, set the RHQ_AGENT_JAVA_HOME environment variable to the JDK home directory in the agent's rhq-agent-env.bat file.
  3. Ensure the Agent is Local to the JBoss Enterprise Application Platform Instance

    Ensure that the RHQ/JBoss Operations Network agent runs locally to and under the same user as the JBoss Application Platform instance. This is required for the Java Attach API to connect to the process.
  4. Import Resources to the Agent Inventory

    RHQ/JBoss Operations Network can now discover resources. These resources can subsequently be imported into the agent inventory.
    When a JBoss Data Grid user deployment enables JMX statistics to expose JBoss Data Grid Cache Managers or caches, the resources appear as children resources of the JBoss Enterprise Application Platform instance.

Chapter 12. The Hello World Quickstart

Hello World is a simple quickstart that illustrates how to store and retrieve data from a cache using Red Hat JBoss Data Grid. For this quickstart, users can access the cache in two ways:
  • from a servlet.
  • from a JSF page using request scoped beans.
All libraries (JAR files) bundles with the application are deployed to JBoss Enterprise Application Platform 6.x. JBoss Data Grid's Library mode only allows local access to a single node in a distributed cluster. This mode also allows the application to access the data grid functionality within a virtual machine in the target container.

Chapter 13. The CarMart Quickstarts

Red Hat JBoss Data Grid includes a transactional and non-transactional CarMart quickstart. The CarMart quickstart is a simple web application that uses JBoss Data Grid instead of a relational database. Information about each car is stored in a cache. Caches are configured declaratively or programmatically depending on the usage mode.
Features

The CarMart quickstart offers the following features:

  • List all cars
  • Add new cars
  • Remove cars
  • View statistics for caches, such as hits, stores, and retrievals
Usage Modes

The CarMart quickstart can be used in the following JBoss Data Grid usage modes:

  • Remote Client-Server Mode, where the application includes the Hot Rod client to communicate with a remote JBoss Data Grid server.
  • Library Mode, where all libraries are bundled with the application in the form of jar files.
Location

JBoss Data Grid's CarMart quickstart is available at the following location: jboss-datagrid-{VERSION}-quickstarts/

13.1. About the CarMart Transactional Quickstart

The transactional version of the CarMart quickstart is a simple web application that uses Red Hat JBoss Data Grid instead of a relational database. Information about each car is stored in a cache. Caches are configured declaratively or programmatically (depending on the usage mode) and run in the same Java Virtual Machine (JVM) as the web application.
Features

The Transactional CarMart Quickstart offers the following features:

  • List all cars
  • Add new cars
  • Add new cars with rollback
  • Remove cars
  • View statistics for caches, such as hits, stores, and retrievals
Usage Modes

  1. Obtain the most recent supported JBoss Data Grid Remote Client-Server Mode distribution files from Red Hat.
  2. Ensure that the JBoss Data Grid and JBoss Enterprise Application Platform Maven repositories are installed and configured. For details, see Chapter 3, Install and Use the Maven Repositories

Procedure 14.1. Build the Football Application

  1. Add Configurations

    Edit the standalone.xml file (located at $JDG_HOME/standalone/configuration/) to add definitions for the datasource and infinispan subsystems.
    1. Add the following subsystem definition for the datasource:
      <subsystem xmlns="urn:jboss:domain:datasources:1.0">
      
      <!-- Define this Datasource with jndi 
      name java:jboss/datasources/ExampleDS -->
      
          <datasources>
              <datasource jndi-name="java:jboss/datasources/ExampleDS" 
      		    pool-name="ExampleDS" 
      		    enabled="true" 
      		    use-java-context="true">
      
                  <!-- The connection URL uses H2 Database 
      		Engine with in-memory database called test -->
      
                  <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url>
      
                  <!-- JDBC driver name -->
                  <driver>h2</driver>
      
                  <!-- Credentials -->
                  <security>
                      <user-name>sa</user-name>
                      <password>sa</password>
                  </security>
              </datasource>
      
              <!-- Define the JDBC driver called 'h2' -->
              <drivers>
                  <driver name="h2" module="com.h2database.h2">
                      <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                  </driver>
              </drivers>
      
          </datasources>
      </subsystem>
    2. Add the following subsystem definition for infinispan:
      <subsystem xmlns="urn:infinispan:server:core:6.0"
      	     default-cache-container="local">
      
      	<cache-container name="local" 
      			 default-cache="default"
      			 statistics="true">
      
      	        <local-cache name="default" 
      			     start="EAGER"
      			     statistics="true">
      
      			<locking isolation="NONE" 
      				 acquire-timeout="30000" 
      				 concurrency-level="1000" 
      				 striping="false"/>
      
      			<transaction mode="NONE"/>
      
      		</local-cache>
      
      		<local-cache name="memcachedCache" 
      			     start="EAGER"
      			     statistics="true">
      
      			<locking isolation="NONE" 
      				 acquire-timeout="30000" 
      				 concurrency-level="1000" 
      				 striping="false"/>
      			<transaction mode="NONE"/>
      
      		</local-cache>
      
      	        <local-cache name="namedCache" 
      			     start="EAGER" 
      			     statistics="true"/>
      	
      	        <!-- ADD a local cache called 'teams' -->
      	
      		<local-cache name="teams"
      		             start="EAGER"
      	         	     batching="false" 
      	         	     statistics="true">
      	
      	            <!-- Disable transactions for this cache -->
      			<transaction mode="NONE" />
      
      	            <!-- Define the JdbcBinaryStores 
      			to point to the ExampleDS previously 
      			defined -->
      
      			<string-keyed-jdbc-store 
      				datasource="java:jboss/datasources/ExampleDS" 
       				passivation="false" 
      				preload="false" 
      				purge="false">
      	
      		                <!-- Define the database dialect -->
      		                <property name="databaseType">H2</property>
      
      	                <!-- specifies information about

      				<string-keyed-table prefix="JDG">
      		                   <id-column name="id" 
      				              type="VARCHAR"/>
      				   <data-column name="datum" 
      				                type="BINARY"/>
      				   <timestamp-column name="version" 
      				                     type="BIGINT"/>
      				</string-keyed-table>
      
      			</string-keyed-jdbc-store>
      
      	        </local-cache>
      
      	        <!-- End of local cache called 'teams' definition -->
      
      	</cache-container>
      </subsystem>

    Note

    The Hot Rod and REST endpoints use the cache named teams and memcached endpoint uses memcachedCache as a default.
  2. Disable REST Security

    As a default, the standalone.xml configuration file protects the REST endpoint with BASIC authentication. This quickstart cannot perform authentication, therefore the REST authentication must be disabled in the REST connector by removing the security-domain and auth-method parameters. The resulting configuration (with REST authentication disabled) is as follows:
    <rest-connector virtual-server="default-host"
                    cache-container="local" />
    For more details about security, see the REST Authentication Chapter in JBoss Data Grid's Developer Guide.
  3. Edit the Submodule Configuration File

    Each submodule (specifically hotrod-endpoint, rest-endpoint and memcached-endpoint) contains a configuration file (located at $JDG_QUICKSTART/src/main/resources/jdg.properties). Modify the default values in the configuration file to set the values required for your specific JBoss Data Grid installation.
  4. Build the Application

    Use the following command to build the example application in its directory:
    mvn clean package
    This step results in the use of Maven's shade plugin, which bundles all dependencies into a single jar file for ease of use. This file is named {PROTOCOL}-endpoint-quickstart.jar, for example rest-endpoint-quickstart.jar for the REST version.
  5. Start JBoss Data Grid

    Run the following script to run JBoss Data Grid:
    $JDG_HOME/bin/standalone.sh
  6. Run the Application

    Run the example application in its directory with the following command:
    mvn exec:java

Chapter 15. The Rapid Stock Market Quickstart

The Rapid Stock Market quickstart demonstrates how JBoss Data Grid's compatibility mode works with a Hot Rod client (to store data) and a HTTP client using REST (to retrieve data). This quickstart is only available in JBoss Data Grid's Remote Client-Server mode and does not use any containers.
The Rapid Stock Market quickstart includes a server-side and a client-side application.

15.1. Build and Run the Rapid Stock Market Quickstart

The Rapid Stock Market quickstart requires the following configuration for the server and client sides of the application.

Procedure 15.1. Rapid Stock Market Quickstart Server-side Configuration

  1. Build a server module for the JBoss Data Grid Server by packaging a class that is common for the client and server in a jar file:
    $ mvn clean package -Pprepare-server-module
    Place the new jar file in a directory structure that is similar to the server module.
  2. Install the server module into the server.
    1. Copy the prepared module to the server:
      $ cp -r target/modules ${JDG_SERVER_HOME}/
    2. Add the new module as a dependency of the org.infinispan.commons module by adding the following into the modules/system/layers/base/org/infinispan/commons/mainmodule.xml file:
      <module name="org.infinispan.quickstart.compatibility.common"/>
  3. Build the application:
    $ mvn clean package
  4. Configure the JBoss Data Grid to use the appropriate configuration file.
    1. Copy the example configuration file for compatibility mode to a location where the JBoss Data Grid Server can locate and use it:
      $ cp ${JDG_SERVER_HOME}/docs/examples/configs/standalone-compatibility-mode.xml ${JDG_SERVER_HOME}/standalone/configuration
    2. Remove the security-domain and auth-method attributes from the rest-connector element to disable REST security.
  5. Start the JBoss Data Grid Server in compatibility mode:
    $ ${JDG_SERVER_HOME}/bin/standalone.sh -c standalone-compatibility-mode.xml

Procedure 15.2. Rapid Stock Market Quickstart Client-side Configuration

  1. In a new command line terminal window, start the client-side application:
    mvn exec:java -Pclient
  2. Use the instructions in the help menu for the client application.
