Error description

  • The strmqm -r command starts the queue manager for replay the
    log files to update the
    manager. After completion of the replay the queue manager
    displays the log extents
    required for queue manager restart recovery and media recovery.
    The queue manager
    also logs the information in the queue manger log files. The log
    extent displayed for
    media recovery was correct, but the log extent logged in the
    AMQ7468 message in the
    queue manager error logs was incorrect.
    
    Output from strmqm -r:
    
    strmqm -r QMGR
    IBM MQ queue manager 'QMGR' is being started for replay.
    The queue manager is associated with installation
    'Installation1'.
    The oldest log file required to start queue manager QMGR is
    S0000006.LOG.
    The oldest log file required to perform media recovery of queue
    manager QMGR is S0000001.LOG.
    IBM MQ queue manager 'BACKUPQMGR' replay completed.
    
    Excerpt from error log:
    
    AMQ7468: The oldest log file required to perform media recovery
    of queue
    manager QMGR is S0000006.LOG.
    
    EXPLANATION:
    The log file S0000006.LOG contains the oldest log record
    required to recreate
    any of the objects from their media images. Any log files prior
    to this will
    not be accessed by media recovery operations.
    ACTION:
    Use this information together with the information in the most
    recent AMQ7467
    message. Archivable log files are all those older than BOTH
    S0000006.LOG and
    the log file mentioned in the AMQ7467 message.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users using a queue manager backup and running the strmqm -r
    command
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    This problem occurred because the queue manager logged the queue
    manager restart extent name instead of the media recovery extent
    name
     in the AMQ7468 message.
    

Problem conclusion

  • The IBM MQ code has been modified to log the media recovery
    extent name in the AMQ7468 message.
