  • Closed as program error.

Error description

  • When WebSphere MQ v7 is used as a messaging provider within
    WebSphere Application Server, delivery of messages to Message
    Driven Beans may be observed to be slower than when using
    WebSphere MQ v6.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of WebSphere Application Server who are
    using the WebSphere MQ messaging provider v7 to deliver messages
    to message-driven beans.
    
    Platforms affected:
     All Distributed (iSeries, all Unix and Windows) +Java
    ****************************************************************
    PROBLEM SUMMARY:
    The options used to retrieve messages for message-driven beans
    could specify the use of message read ahead when not
    appropriate, which impacted performance.
    

Problem conclusion

  • The WebSphere MQ classes for Java Message Service (JMS) have
    been updated to only specify the use of read ahead when it will
    optimize  the reading of messages from a WebSphere MQ v7 queue
    manager.
