APAR status

  • Closed as program error.

Error description

  • The message which is in transit is getting lost when a WebSphere
    MQ XMS .NET V2.0 CLIENT application is closing the session,
    consumer or connection. This happens only for non-persistent
    non-transacted sessions.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of XMS .NET applications which run as synchronous
    consumers operating with non-persistent and non transacted
    messages in Managed connection mode.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    The Session, Consumer or Connection close method was not
    waiting for the asynchronous message delivery thread to complete
    the operation. This was causing the main thread to close before
    completing the consumption of messages which are available in
    client side.
    

Problem conclusion

  • An appropriate locking mechanism is introduced to wait for the
    asynchronous delivery thread to complete the message processing
    before closing the Session, Consumer or Connection.
