Restoring an Oracle Database to Disk

You can restore a specific backup job or multiple backup jobs at the same time directly to a location on a disk without the use of Oracle. This is useful for restoring multiplexed data on the same media. These restores are also useful for troubleshooting network errors. The data from different backup jobs are passed to the client so that all of the interleaved backup jobs can be restored in parallel. You can restore the data associated with specific backup jobs, such as full, incremental, or archive log, in parallel streams. You can also submit multiple restore jobs from full and incremental backups.

The procedure restores the archive files (backup sets) to a disk. To restore files to the database, you must use the Oracle agent.

Before You Begin

  1. Install the Oracle agent on the destination client.

  2. Verify that there is enough disk space for the backup pieces that are restored.

  3. If you want to catalog the backup pieces after the restore, the Oracle user must have the correct permissions.


  1. From the navigation pane, go to Protect > Databases.

    The Instances page appears.

  2. Click the instance.

  3. The instance page appears.

  4. On the Overview tab, in the Recovery points section, select the backup to restore, and then click Restore.

    The Backup content page appears.

  5. Select the data that you want to restore, and then click Restore.

    The Restore options dialog box appears.

  6. In the Restore to disk tab, from the Destination client list, select the client to restore to.

  7. In the From time and To time boxes, specify the time period you want to select the jobs from.

  8. From the Job(s) list, select the backup jobs to restore to disk.

  9. In the Destination folder box, specify where you want the backup pieces restored.

    If the destination is an NFS share, the hosting NFS server must have the "no_root_squash" option enabled.

  10. To use an account other than the one configured for the Oracle instance, move the Impersonate user toggle to the right and enter the user's credentials.

    The account must have the necessary write privileges on the location for the restored data.

  11. Click Submit.

What to Do Next

  1. When the restored backup pieces are unknown to the RMAN repository, catalog the restore disk pieces. For more information, see Cataloging Backup Pieces Restored to Disk after an Application Free Restore.

  2. Perform an RMAN restore (for example, restore the database, restore the control file or recover the database). For more information, see Oracle Restore Examples Using the RMAN Command Line Interface.
