IT29614: ORACLE DATABASE BACKUP JOB SHOWS ERROR INDICATING MOUNT POINT ISIN USE

APAR status

• Closed as program error.

Error description

• When using IBM Spectrum Protect Plus to backup an Oracle
  database, the backup job ends with FAILED or PARTIAL status.
  The following errors are seen in the job log:
  
  "Cannot mount volume <path> because the mount point is in use."
  
  "Failed to perform backup of db <name> on application server
  <server>: Failed to mount backup destination"
  
  These errors occur when the previous run of the backup job
  had completed successfully but was unable to unmount the
  backup target volume at the end of the job.
  

Local fix

• Make a note of the <path> mentioned in the error message
  indicating the mount point is in use. On the Oracle server
  run the following command to manually unmount the path, then
  retry the backup job.
  
  umount -f <path>

Problem conclusion

• When attempting to mount a backup volume, the Oracle Agent uses
  a mount point path that is unique to each backup volume. If the
  mount point is already in use because of an unmount failure
  during the previous backup job, the agent mistakenly reports an
  error. The problem has been resolved by improving the mount
  point check logic. If the mount point is in use by the same
  volume whose mount is being attempted, the agent proceeds
  without reporting an error.
