COMMAND
vcdba_create
SYNOPSIS
vcdba_create -s <oracle_sid> -p <primary_host>
[-o online|offline|datafile|archonly] [-v]
DESCRIPTION
Creates a virtual copy of a database instance.
The vcdba_create command can be used to create an online or offline virtual copy of an
Oracle database, a datafile only virtual copy, or an archive log virtual copy.
■ Online or offline virtual copy - A consistent point-in-time snapshot image of the database
while it is OPEN (online) or CLOSED (offline), respectively.
■ Datafile only virtual copy - A snapshot image of all datafiles, not include archive log
destinations, of the database while it is OPEN. A virtual copy create with the
-o datafile option is only useful when archive logfiles generated during the creation of
the virtual copy are also available. You may wish to create separate virtual copies using the
-o archonly option, or use another method to backup archive log destinations.
■ Archive log virtual copy - A snapshot image of the archive log destination only.
Once created, the virtual copy can be mounted on the backup host for off-host processing
purposes such as backup and database cloning.
A database virtual copy consists of multiple virtual copies of underlying 3PAR virtual volumes
used by the Oracle datafiles and/or archive log destination depending on which option is
specified ( online , offline , datafile, or archonly ). An archive log virtual copy can be used
in conjunction with online or offline virtual copies to simulate an incremental backup.
If Recovery Manager is configured to use Oracle RMAN for backup, an RMAN Recovery Catalog
must have been created and configured prior to running this command. The vcdba_create
command will initiate an RMAN catalog synchronization during the virtual copy creation
process.
To use the vcdba_create command, the Oracle database structure must satisfy the following
requirements:
■ The database must be running in archive log mode and automatic archival must be enabled
in order to create an online, datafile, or archive log virtual copy.
