In the install guide Jboss EAP for IBM Db2 "https://pdn.pega.com/documents/pega-731-platform-installation-guide-jboss-redhat-eap-and-ibm-db2-linux-unix-and-windows", under "Setting application deployment parameters", there is a mention of the statement "To use the EAR file when you deploy, add the configuration for the pooled connection factory". We are trying to use standalone.xml and there is no element called <subsystem xmlns=”urn:jboss:domain:messaging-activemq:1.0”>. This element is only found in standalone-full.xml. Does this mean we have to only use standalone-full.xml for Pega ear deployments ? Also, the step is listed as optional and so is it necessary for all ear deployments?
If you want to perform the EAR deployment then it is recommended to use standalone-full.xml file, you can search for "standalone-full.xml" text in your share PDF document link and you can notice that for ear related deployments they are referring to only standalone-full.xml file and for WAR deployments they referred both standalone.xml and standalone-full.xml.
By the way the above step is mentioned as optional which means that ignoring this step doesn't cause you the installation failure. So its upto you to decide whether you want to implement this feature or not based on your requirement as per my understanding.
