16.4.2. Change Database for the JMS Services

The JMS service in the JBoss Enterprise Application Platform uses relational databases to persist its messages. For improved performance, we should change the JMS service to take advantage of the external database. To do that, we need to replace the file <JBOSS_HOME>/server/<PROFILE>/deploy/messaging/$DATABASE-persistence-service.xml with the $DATABASE-persistence-service.xml filename depending on your external database.
