The WebLogic uses "Persistent Store " to store subsystems data, such as persistent JMS messages. It defaults to use File Store, but you can customize to use database instead. To do this, you would need to create a DataSource first, and ensure to UNCHECK the "Supports Global Transactions" feature. Basically you need to create an NON-XA DataSource in order to use it in Persistent JDBCStore. Otherwise you will not able to see your datasource as option to use.
