Error description

  • In .NET, if you set the TRANSPORT_PROPERTY to
    MQC.TRANSPORT_MQSERIES_CLIENT and try to get a message with
    option MQC.MQGMO_CONVERT then you will get the following
    exception during execution of method queue.Get(Message, GMO):
    
    Exception caught: System.EntryPointNotFoundException: Unable to
    find an entry point named 'zstMQGET' in DLL
    'C:\Program Files(x86)\IBM\WebSphere MQ\bin64\mqic.dll'.
    at IBM.WMQ.MQDestination.Get(MQMessage message,
    MQGetMessageOptions gmo, Int32 maxMsgSize)
    at IBM.WMQ.MQDestination.Get(MQMessage message,
    MQGetMessageOptions gmo)
    at SimpleGet.SimpleGet.GetMessages()
    at SimpleGet.SimpleGet.Main(String[] args)
    

Local fix

  • 1 - Do not use the option MQGMO_CONVERT
    or
    2 - Use MQC.TRANSPORT_MQSERIES_MANAGED instead of CLIENT
    or
    3 - Use the function queue.Get(Message, GMO, maxMsgSize);
    instead of queue.Get(Message, GMO);
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of WebSphere MQ v7.1 and v7.5 unmanaged .NET client
    applications.
    
    Platforms affected:

    ****************************************************************
    PROBLEM SUMMARY:
    The WebSpehere MQ .NET layer invokes the native function
    zstMQGET when run in unmanaged mode. The
    System.EntryPointNotFoundException is reported since this
    function had not been exported by the mqic library.
    

Problem conclusion

  • The WebSphere MQ code has been modified to export the zstMQGet
    function from mqic.dll.
