Tuning messaging

To tune asynchronous messaging, you can, for example, configure message-driven bean (MDB) throttling for a JCA 1.5-compliant messaging provider. On z/OS® platforms you can tune also MDB processing and tune destinations for the WebSphere® MQ messaging provider.

About this task

To tune your asynchronous messaging, complete one or more of the following steps.

• Configure MDB throttling for a JCA 1.5-compliant messaging provider in one of the following ways, depending on your choice of messaging provider:
  • For the default messaging provider, complete the task Configuring MDB throttling for the default messaging provider.
  • For the IBM MQ messaging provider, either set the maximum server sessions property on the IBM MQ messaging provider activation specifications advanced properties page, or the maxPoolSize property when using the createWMQActivationSpec or modifyWMQActivationSpec wsadmin commands.
  • For a third-party JCA 1.5-compliant JMS messaging provider, refer to the generic method of message throttling described in Throttling inbound message flow for JCA 1.5 message-driven beans.
• Tune MDB processing on z/OS.
• Tune messaging destinations for the WebSphere MQ.
