Selecting Volumes Manually (SAP Library - Database Administration (Oracle) with SAPDBA)

Selecting Volumes Manually

Use

You can also select the volumes for a backup manually. You can do this if the BRBACKUP/BRARCHIVE volume management is deactivated by using the reserved volume name SCRATCH. The appropriate SAP program checks the expiration period. .

Prerequisites

Make sure that initialized volumes are available for the backup.

Determine whether the required expiration period has been configured in profile parameter expir_period ; change the value when necessary.

Procedure

There are two ways to start the backup with BRBACKUP or BRARCHIVE:

Enter the following parameter values in profile init<DBSID>.sap : volume_backup = SCRATCH or volume_archive = SCRATCH

Then start BRBACKUP/BRARCHIVE.

Leave the profile unchanged (a volume pool may be defined).

Start BRBACKUP/BRARCHIVE with the option -v SCRATCH .

Result

The SAP programs BRBACKUP and BRARCHIVE request the number of scratch volumes needed for the backup (message BR104I), expired volumes with any name. The volume names in the labels are not changed by the backup operation. Any expired BRBACKUP/BRARCHIVE volumes are accepted. See Volume Expiration Period.

If you use scratch volumes, it may make sense (primarily for reasons of clarity) to include the weekdays or days of the month in the volume names.
