Error description

  • A client application using XMS .NET V2.0 and connecting to

    2046 MQRC_OPTIONS_ERROR.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Client applications using XMS .NET v2.0 to connect to a
    WebSphere MQ v6 queue manager and using the Publish / Subscribe
    model.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    The 2046 MQRC_OPTIONS_ERROR occurs within the method named
    WmqSubscriptionEngine.CleanupUnconsumedMessages(). Within this
    method an MQGET call has MQGMO_PROPERTIES_FORCE_MQRFH2 set as
    one of the MQGMO get message options. The WMQ v6 queue manager
    does not support MQGMO_PROPERTIES_FORCE_MQRFH2 and thus WMQ v6
    returns 2046 MQRC_OPTIONS_ERROR.
    

Problem conclusion

  • When setting the MQGMO_OPTIONS for the MQGET call within
    WmqSubscriptionEngine.CleanupUnconsumedMessages(), there was an
    error in determining the command level of the queue manager and
    hence the MQGMO_PROPERTIES_FORCE_MQRFH2 was set for a V6 queue
    manager incorrectly. It has now been corrected such that this
    option is set only when connecting to a V7 queue manager.
