Recovery Manager with Oracle Standby Database
Recovery Manager 3.0.3/3.0.4 for Oracle User’s Guide
If the virtual copy is to be backed up using Oracle RMAN, a Recovery Catalog must have been
created and configured prior to using the backup utility.
For an RAC database, archive log destinations of all RAC instances must be on shared storage
(same cluster file systems or same ASM disk groups).
2.11.2 The Database Restoration Utility
3PAR Recovery Manager’s database restoration utility restores databases, tablespaces,
datafiles, or archive logs from a virtual copy's backup image. The virtual copy must have been
previously backed up using the
vcdba_backup command. The virtual copy must have a
backup status of
Y in order to be restored. The virtual copy's backup status can be retrieved
using the Recovery Manager display utility (see 2.6.3 The Virtual Copy Display Utility on
page 2.9).
The Recovery Manager restore utility can also be used to restore a virtual copy's backup image
to an alternate server. For an NBU (user-managed) restoration, the restore utility can also be
used to restore to an alternate location.
The following restrictions apply when restoring from a virtual copy's backup image:
■ When restoring the database control file (using the -c option) using Oracle RMAN, the
database must be in STARTED mode (startup nomount). In addition, restoring the
database control file along with the individual datafile or tablespace is not supported as it
is not possible to perform media recovery.
■ When restoring a database, the database must be in CLOSED or MOUNTED mode for NBU
restore or Oracle RMAN restore, respectively. For an RAC database, all RAC instances must
be in CLOSED or MOUNTED mode.
■ When restoring individual tablespaces or datafiles, the database can be OPEN, but the
corresponding tablespaces must be offline.
■ If the database is an ASM managed database, all ASM disk groups must be mounted prior
to running the restore utility.
■ For an NBU (user-managed) restoration, the /usr/openv/netbackup/db/altnames/
<database_hostname|virtual _hostname>
file must be created on the NBU master
server prior to running the restore utility, where
<database_hostname|virtual_hostname> is the host name of the database server.
