2.5. Configuring and running Business Central in a cluster

Procedure

1. Mount the directory shared over NFS as /data. Enter the following commands as the root user:

   mkdir /data
   mount <NFS_SERVER_IP>:<DATA_SHARE> /data

   Replace <NFS_SERVER_IP> with the IP address or hostname of the NFS server machine. Replace <DATA_SHARE> with the share name that you configured (for example, /opt/kie/data).

2. Open the EAP_HOME/standalone/configuration/standalone-full.xml file in a text editor.

3. Edit or add the properties under the <system-properties> element and replace the following placeholders:

   • <AMQ_USER> and <AMQ_PASSWORD> are the credentials that you defined when creating the AMQ Broker.
   • <AMQ_BROKER_IP_ADDRESS> is the IP address of the AMQ Broker.

   • <INFINISPAN_NODE_IP> is the IP address where Red Hat Data Grid is installed.

     <system-properties>
       <property name="appformer-jms-connection-mode" value="REMOTE"/>
       <property name="appformer-jms-username" value="<AMQ_USER>"/>
       <property name="appformer-jms-password" value="<AMQ_USER_PASSWORD>"/>
       <property name="appformer-jms-url"
          value="tcp://<AMQ_BROKER_IP_ADDRESS>:61616?ha=true&amp;retryInterval=1000&amp;retryIntervalMultiplier=1.0&amp;reconnectAttempts=-1"/>
       <property name="org.appformer.ext.metadata.infinispan.port"
          value="11222"/>
       <property name="org.appformer.ext.metadata.infinispan.host"
          value="<INFINISPAN_NODE_IP>"/>
       <property name="org.appformer.ext.metadata.infinispan.realm"
          value="ApplicationRealm"/>
       <property name="org.appformer.ext.metadata.infinispan.cluster"
          value="kie-cluster"/>
       <property name="org.appformer.ext.metadata.index"
          value="infinispan"/>
       <property name="org.uberfire.nio.git.dir"
          value="/data"/>
       <property name="es.set.netty.runtime.available.processors"
          value="false"/>
     </system-properties>

4. Optional: If the Red Hat Data Grid deployment requires authentication, edit or add the properties under the <system-properties> element and replace the following placeholders:

   • <SERVER_NAME> is the server name specified in your Red Hat Data Grid server configuration.

   • <SASL_QOP> is the combination of auth, auth-int and auth-conf values for your Red Hat Data Grid server configuration.

     <property name="org.appformer.ext.metadata.infinispan.server.name"
        value="<SERVER_NAME>"/>
     <property name="org.appformer.ext.metadata.infinispan.sasl.qop"
        value="<SASL_QOP>"/>
     <property name="org.appformer.ext.metadata.infinispan.username"
        value=""/>
     <property name="org.appformer.ext.metadata.infinispan.password"
        value=""/>

5. Save the standalone-full.xml file.

6. To start the cluster, navigate to EAP_HOME/bin and enter one of the following commands:

   • On Linux or UNIX-based systems:

     $ ./standalone.sh -c standalone-full.xml

   • On Windows:

     standalone.bat -c standalone-full.xml
