# Configuring SAP for Oracle Subclients for Archive Log Backups

You can use archive logs backups to recover database transactions that have been lost due to an operating system or disk failure.

You can apply the archive logs to an online backup to recover the database.

Best Practice: Create separate subclients to backup log files because they are mandatory for recovering data.

Note

- If the archive log destination is different from the default $SAPDATA_HOME/saparch location, configure the <SID>_sSAPARCH Additional Setting to enable the CommCell Console backup and obtain the new SAPARCH location.

- The archive log backups initiated from the CommCell Console use BRARCHIVE with the -OSC syntax and only permit one backup cycle. For more information, see the SAP note 214370.

## Before You Begin

Add a Database Instance.

## Procedure

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

   The database Overview page appears.

2. Go to the Instances tab.

3. Click an instance.

4. Go to the Subclients tab.

5. Click the Add Subclient tab, and enter the information for the subclient:

   - In the Subclient name box, enter a name for the subclient.

   - From the Plan list, select the backup plan to use for the subclient.

   - In the Number of data streams box, enter the number of streams to use to back up the subclient.

   - For Backup mode, specify the data to include in backups of the subclient:

     - Selective online full: Runs only full backup jobs.

     - Online database: Backs up the entire database when it is online.

     - Subset of online database: Backs up a subset of the database when it is online.

     - Offline database: Backs up the entire database when it is offline.

     - Consistent online: Backs up the data and the offline redo logs that are generated during the data backup.

   - For Backup device, select either util_file or util_file_online as a interface for the backup of the subclient.

6. Specify how to back up archive logs:

   - Select the Archive log backup check box.

     - Optional: To delete the archive logs after they are backed up, select the Delete backed up archive logs check box.

     - Optional: To disable log switching for the current redo log, Select the Disable switch current log check box.

     - Optional: To create a secondary copy of the archived offline redo log files, select the Create second copy for logs check box.

       Note

       - If you use the rman_util device for SAP Log backups, you must use the second copy.

       - If you use the util_file device for SAP Log backups, you must use the Commvault Auxiliary copy operation.

7. Click Save.
