The persistent store provides a built-in, high-performance storage solution for WebLogic Server subsystems and services that require persistence. For example, it can store persistent JMS messages or temporarily store messages sent using the Store-and-Forward feature. The persistent store supports persistence to a file-based store or to a JDBC-enabled database.
Table defines many of the WebLogic services and subsystems that can create connections to the persistent store. Each subsystem that uses the persistent store specifies a unique connection ID that identifies that subsystem.
