Concepts and considerations for MDB settings on z/OS

To be able to tune the processing of endpoint message-driven beans (MDBs), you need to understand the concepts and considerations for the MDB settings that you configure.

When a message-driven bean is mapped (that is, listening to) a queue, or to a topic through a durable subscription, a JMS message first enters into the WebSphere server in the controller, so we say the server is "listening in the controller" for these messages. The "listening in the controller" term is used throughout this description of tuning MDB processing.

The following sub-topics provide a set of information that describe the concepts and considerations that you should be aware of to be able to configure MDB settings on z/OS:
