  • Closed as program error.

Error description

  • Working with WebSphere MQ File Transfer Edition V7.0.4. The FTE
    resource monitor " message to file transfer " does not work
    properly, if message grouping is used. In case messages are put
    on a queue in an unordered manner, where messages that belong to
    a messageGroup are put on the the queue mixed with messages that
    do not belong to a messageGroup, not all messages are written to
    the final destination.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of WebSphere MQ File Transfer Edition
    7.0.4 and WebSphere MQ Managed File Transfer 7.5 who are using
    the message to file transfer feature to transfer message groups.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    When specifying a message to file transfer the user can define
    the group id of the message group that will be transferred.
    The WebSphere MQ FTE/MFT agent should then wait until the
    complete group of messages is available on the queue before
    reading them off the queue.
    
    If first message defined in the group was not the first
    message physically on the queue then the FTE/MFT agent would not
    read this message. The FTE/MFT agent incorrectly read the
    grouped message closest to the front of the queue rather than
    the first logical message in the group on the queue. The
    result is that the file at the destination side would only
    contain a subset of the expected message data, the transfer
    log would report no error and the message count contained within
    the transfer log would be correct for the data that was
    transferred i.e. if a message group contained 10 messages but
    only 8 messages were transferred then the message count would be
    8.
    

Problem conclusion

  • The FTE/MFT agent has been modified to retrieve the first
    logical message in the group when processing a message to file
    transfer that is using message groups.
