Applies to:Oracle Containers for J2EE - Version 10.1.3.3.0 to 10.1.3.5.0 [Release AS10gR3]
Information in this document applies to any platform.
A J2EE application consisting of message-driven bean is deployed into 10.1.3.3 OC4J. The message-driven bean consumes JMS message via Resource Adapter based on Oracle Database persistence provider.
Depending on the JMS messages load, the message-driven bean is configured so that the MDB listener threads number can have a value between MinListenerThreads (mininum of listener threads), MaxListenerThreads (maximum of listener threads). However, the number of listener threads should not decrease below MinListenerThreads when there is a low message activity.
This note shows how to enable listener threads pooling.
