vcdba_create

SYNOPSIS

vcdba_create -s <oracle_sid> -p <primary_host> [-o onlineofflinedatafilearchonly] [-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.
