Use
This section describes how you can use
BRBACKUP to perform a split-mirror online backup with your Oracle database. We especially recommend this for large databases where high availability is an important consideration.In an online backup the system remains available the whole time. The tablespaces to be backed up are temporarily set to BACKUP status while the mirror disks are split. In comparison to the normal online backup, in which the tablespaces retain this status during the whole backup period, the amount of redo information is significantly reduced.
Prerequisites
You set the following parameters in the
initialization profile init<DBSID>.sap:Instead of the
backup_type parameter, you can enter the BRBACKUP command option -t|-type as shown below in "Activities." The BRBACKUP command option takes priority.Activities
