Procedure 5.1. 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}-GA. 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 standalone-storage-only.xml file, which contains the configuration for a node with no endpoints.

Procedure 7.1. 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:

   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();
       }
    }

Procedure 9.1. 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"
   

   Copy to Clipboard Toggle word wrap
   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.

      </subsystem>
      

      Copy to Clipboard Toggle word wrap

   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" />
   

   Copy to Clipboard Toggle word wrap
   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
   

   Copy to Clipboard Toggle word wrap
   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
