vcdba_rollback

SYNOPSIS

vcdba_rollback -s <oracle_sid> -p <primary_host> -t <timestamp> 

[-o data|arch] [-v] [-w] [-f]

DESCRIPTION

Rolls back database volumes from an online virtual copy.

The vcdba_rollback command promotes a virtual copy’s volumes back to their base virtual 

volumes. The base virtual volumes used by the database are rolled back to the virtual copy’s 

volumes. Once the promote (rollback) process completes successfully, the base virtual volumes 

will be exactly the same as the virtual copy’s volumes. If the base volume size has been changed 

since the virtual copy was taken, the rollback process will not affect the new size.

When rolling back from an online virtual copy, both datafile and archive log virtual volumes 

are rolled back by default. Use the -o option to roll back only datafile virtual volumes or only 

archive log virtual volumes. 

When rolling back from an offline virtual copy, only datafile virtual volumes are rolled back.

When rolling back from an archive log virtual copy, only archive log virtual volumes are rolled 

back.

The following restrictions apply when rolling back a virtual copy:

The online redo logs and control file should not reside on the same virtual volumes used by 

the datafiles and archive logs. Otherwise, they will be rolled back along with the datafile 

and archive log virtual volumes.

The database instance must be CLOSED for this operation. If the database is an RAC 

database, all RAC instances must be CLOSED.

The base (data file and/or archive log) virtual volumes must not be exported.

The specified virtual copy must have an Available (not mounted) status.

If the base virtual volumes are involved in a Remote Copy group you must use -f to 

promote the virtual copies back to their base volumes.
