APAR status

  • Closed as program error.

Error description

  • Using an unmanaged 64-bit .NET client application with
    MQPutMessageOptions.Version = MQPMO_VERSION_2 fails with
    reason code 2156 MQRC_RESPONSE_RECORDS_ERROR.
    
    This happens only when the .NET client application is compiled
    for 64-bit CPU or AnyCPU.
    

Local fix

  • Compile the .NET client application for 32-bit CPU.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of unmanaged WebSphere MQ .NET client who use
    MQPuMessageOptions.Version = 2 or higher on 64-bit machines
    with client applications compiled for x64 or AnyCPU.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    Two fields of the MQPMO structure were declared with an
    incorrect data type causing the size of the MQPMO structure to
    differ in the .NET layer and the native layer. This caused the
    native C layer to report a MQRC_RESPONSE_RECORDS_ERROR as it
    attempted to access an inaccessible address on the memory.
    

Problem conclusion

  • The fields of the MQPMO structure were modified to have the
    correct data types.
