Perform a Backup in Online Mode

You can perform a backup in the online mode using the following procedure.

Note: Before opening the Backup Manager, ensure that Oracle Server is running and that all of the tablespaces in the databases you want to back up are online. Also, start the Arcserve Backup and the Agent.

To perform a backup in the online mode

1. Open the Backup Manager, select the Source tab, and expand the Windows Agents.
2. In the Windows Agents list, click the green marker on the host on which Oracle is installed.

   The Login dialog opens.

3. Enter the host user name and password, and then click OK.

   Note: Expand the host if it did not expand automatically.

4. Select an Oracle database.

   The Database Login dialog opens.

5. Enter the Oracle DBA user name and password.

   Note: Ensure that the Oracle user name and password that you use to connect to Oracle has the sysdba privileges.

   When backing up a database, a single master job is created in the queue. When the backup begins, the master job calls RMAN, which launches the child jobs.

   The child jobs appear in the job queue.

6. To set the backup options, select the Source tab and right-click to select Local Options.

   The Agent for Oracle Backup options dialog opens.

   Note: In the Oracle Backup Options dialog, ensure that the value in the Number of Channels (Streams) option is between 1 and 255. As this parameter affects the Agent, RMAN determines the actual number of channels (streams) needed for the backup and restore job.

7. Select Back up Oracle database with RMAN mode option to enable the fields.
8. Enter information in the Oracle Backup Options tab fields to perform an online backup.

   Click OK.

9. (Optional) Select the Advanced Oracle Backup Options tab. Specify the options that you require for the job and click OK.
10. Select the Destination tab, and then select the media device group and media in which you want to store the backup.

    Important! If you set the Number of Channels option to a number higher than one, do not select a specific media or media device group on the Destination tab.

11. Click the Method/Schedule tab, and select one of these schedule types:
    • Custom
    • Rotation
    • GFS Rotation
12. Click Submit on the toolbar.

    The Submit Job dialog opens.

13. Complete the required fields on the Submit Job dialog and click OK.

The job is submitted. You can monitor the job on the Job Status Manager.

Note: For information about restrictions related to monitoring your backups, see Backup and Restore Limitations using the RMAN Mode.

A backup can take up multiple sessions on the media even if you choose only one object. For example, if you enter a limit on the Backup Set Size field on the Advanced Oracle Backup Options tab, it will create multiple sessions.
