Disabling Failovers during Oracle Restores

During restore operations, RMAN automatically looks for another copy of the file under the following circumstances:

  • a backup piece is corrupted or deleted
  • a MediaAgent is offline
  • a block in the backup is corrupted within the latest full backup

When you select this check box, the Commvault software does not restore from a failover backup piece. The Oracle behavior remains the same, that is it fails over to another backup piece name.

The Commvault software enables this option by default because it might print restore database corruptions.


  1. From the CommCell Browser, go to Client Computers > client > Oracle.
  2. Right-click the instance, then go to All Tasks > Browse and Restore.

    The Browse and Restore Options dialog box appears.

  3. Select Latest Backup, and then click the View Content button.
  4. Optional: Use non-default browse and restore options. For more information, see Browse and Restore.
  5. Select the database, and then click the Recover All Selected button.

    The Oracle Restore Options dialog box appears.

  6. Depending on the type of restore to be run, click Restore in place or Restore out of place, and then click Next.

    The Oracle In Place Restore Options or Oracle Out of Place Restore Options dialog box appears.

  7. Click Advanced.
  8. Click the Options tab.
  9. Select the Disable Oracle Channel Restore Failover check box.
  10. Click the Copy Precedence tab and select the Restore from Copy Precedence check box.
  11. In the Copy Precedence box, type the copy precedence number for the backup copy.
  12. Click OK.
