APAR status

  • Closed as program error.

Error description

  • Display Queue Status, MSGAGE Attribute may show very large
    values even if there are no messages on the displayed queue.
    

Local fix

Problem summary

  • Due to the asynchronous nature of transaction handling
    on HPE NonStop it can happen that messages are found in
    the internal message chain, but not on the file system
    anymore (e.g. MQPUT followed by ABORTTRANSACTION).
    In such cases a timestamp of value zero is compared to
    current time resulting in it being seen as the oldest
    known MSGAGE.
    

Problem conclusion

  • The product has been changed to use a timestamp of a non
    zero value if it should run into the affected code paths.
