DSNU1626I csect-name - system-utility SYSTEM UTILITY FAILED BECAUSE RESTORE SYSTEM IS ALREADY RUNNING OR ANOTHER TASK IS PROCESSING IN A MANNER THAT PREVENTS THIS TASK FROM SERIALIZING PROPERLY

Explanation

The attempt to acquire the serialization lock failed. In the case of RESTORE SYSTEM, this can only occur if RESTORE SYSTEM is already running. In the case of BACKUP SYSTEM, this can occur if any of the following events are in process:
  • System checkpoint
  • Data set extensions
  • Writing 32K pages
  • Writing close page set control log records (PSCRs)
  • Creating data sets (for table spaces, indexes, and so on)
  • Deleting data sets (for dropping tables spaces, indexes, and so on)
  • Renaming data sets (for online reorganizing of table spaces, indexes, and so forth during the switch phase)

System action

The utility is terminated.

System programmer response

If it is the RESTORE SYSTEM utility that is being invoked, the only other utility that can be running is RESTORE SYSTEM. If it is the BACKUP SYSTEM utility that is being invoked, any system activity that provokes any of the processes listed in the Explanation above could be the cause of the failure. If possible, determine which utility is responsible and resubmit this job once that utility completes. You may also resubmit your job at a later, less busy time.
