  • Closed as program error.

Error description

  • The exception is seen in the listener or channel pool (amqrmppa)
    process of a WebSphere MQ server system when processing requests
    from a publish/subscribe application using the WebSphere
    MQ .Net classes. The exception is only seen when the client
    application runs on a 64-bit Windows platform.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users running 64-bit WebSphere MQ .Net client publish/subscribe
    applications.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    The problem was caused by the inclusion of variable size data
    pointers in the transmission segment header which was sent to
    the queue manager on the client connection. On a 64-bit
    system, this resulted in 64-bit data whereas on a 32-bit system,
    this resulted in 32-bit data. However, in the protocol defined
    for communications between the client and queue manager this
    data is specified as always 32-bit. The exception occurs as the
    queue manager must always interpret this data as 32-bit,
    irrespective of the underlying system architecture.
    

Problem conclusion

  • The WMQ .Net client is corrected to ensure data is sent in the
    32-bit format mandated by the protocol.
