Updating a backup queue manager

 

To ensure that a backup queue manager remains an effective method for disaster recovery it must be updated regularly. Regular updating lessens the discrepancy between the backup queue manager log, and the existing queue manager log. To update a backup queue manager, do the following:

1. Copy all the log extents that have been completed since the last update from the existing queue manager log directory to the backup queue manager log directory.

2. Execute the following control command on the backup queue manager:

   strmqm -r BackupQMName

   This replays all the copied log extents and brings the backup queue manager in step with the existing queue manager. Once complete, a message is generated which identifies all the log extents required for restart recovery, and all the log extents required for media recovery.
   Warning: If you copy a non-contiguous set of logs to the backup queue manager log directory, only the logs up to the point where the first missing log is found will be replayed.
