# Restoring an Oracle RAC 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.

## Procedure

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

   The database overview page appears.

2. On the Instances tab, click the instance.

   The instance properties page appears.

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

   The Backup content page appears.

4. Select the data that you want to restore, and then click RESTORE.

   The Restore options dialog box appears.

5. Select the Out of place option.

6. From the Restore type list, select Restore to disk.

7. From the Destination client list, select the server to restore to.

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

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

10. 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.

11. 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.

12. To specify pre or post recovery scripts, do the following under Pre or Post options:

    1. Type the path to the script.

    2. To run a script as a specific user, move the Run as user toggle to the right and then select a saved credential.

13. You can configure a schedule to repeat this restore operation. To create a schedule, do the following:

    1. Click Schedule.

       The Add schedule dialog box appears.

    2. In the Name box, type a name for the schedule.

    3. Configure the Frequency and Repeat parameters.

    4. To specify exceptions to the schedule, click Exceptions.

       The Exceptions dialog box appears.

    5. Configure the exception parameters:

       - You can click Add Exception to save a set of exception parameters and continue adding sets of exception parameters.

       - Click Save when you have finished configuring the exception parameters.

    6. Under the Range of recurrence section, specify the Start date and End date to schedule the recurrence range of the restore operation.

    7. To save the schedule and return to the restore dialog box, click Schedule.

14. 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, you can recover the database, or restore the control file or database. For information about recovering the database, see Recovering an Oracle Database after an Application-Free Restore.
