2.11 Recovery Manager with Oracle Standby Database
All 3PAR Recovery Manager’s utilities can be run against an Oracle physical standby database
instead of the production database. This completely eliminates the performance impact on the
production database.
In addition to the current Recovery Manager’s limitations and restrictions when running
against an Oracle primary database, the following limitations and restrictions apply when
running against an Oracle physical standby database:
■
Only Oracle 10g or above is supported.
■
A standby database must be a physical standby database. Logical and snapshot standby
databases are not supported.
■
If using Oracle RMAN for backup, the primary database, and not the standby database,
must be registered with Oracle Recovery Catalog.
■
A snapshot of a standby database can be used to promote back to the standby database
volumes but it cannot be used to promote back to the primary database volumes.
■
Oracle parameter file and control file are not compatible between the standby database
and the primary database. They cannot be used to restore to the primary database unless
Oracle RMAN (11g) is used for restoring. This means that the Oracle parameter file and
control file of the primary database must be backed up manually outside of the Recovery
Manager for Oracle.
2.11.1 The Database Backup Utility
3PAR Recovery Manager’s database backup utility supports full and/or incremental backup of
an Oracle database or archive log destination. Full backup of an Oracle database or archive log
destination are always supported regardless of backup method (NBU backup or Oracle RMAN
backup). However, incremental (differential or cumulative) backup of a whole Oracle database
is only available using Oracle RMAN backup. Incremental (differential or cumulative) backup of
archive log destination is only available for the NBU (user-managed) backup method.
