Use
You can use
BRBACKUP to back up your large Oracle database to multiple disks in parallel.Prerequisites
You must define the directories with the
backup_root_dir parameter.Features
Activities
To avoid imposing extra processing load on the database server during the second phase of a two-phase backup, consider the following procedure instead:
A requirement for this procedure is that the hard-disk controllers for the backup disks can be physically mounted on both hosts simultaneously. The unmount and mount operations – that is,
umount and mount – are necessary, since the file system cannot be mounted on different computers at the same time due to the buffering mechanism.Alternatively, you can
back up directly to remote disks. This eliminates the need for umount and mount.Another approach to reduce processing load on the production database host is to use
split-mirror disk backup.
