COMMAND
vcdba_set
SYNTAX
vcdba_set -s <oracle_sid> -p <db_host> -t <timestamp> -r
<time>{d|D|h|H} -f [-v]
DESCRIPTION
The vcdba_set command sets or extends a read-only virtual copy’s retention time. If the
volumes do not belong to a domain, the sets or volumes’ retention time cannot exceed the
value of the system’s VVRetentionTimeMax . The default value for the system’s
VVRetentionTimeMax is 14 days. If the volumes belong to a domain, then the read-only
virtual copy’s retention time cannot exceed the value of the domain’s VVRetentionTimeMax ,
if set. The retention time cannot be removed or reduced once it is set. The vcdba_display
command with -r option can be used to display all virtual copy volumes with their
corresponding retention time.
Requirements for setting retention time:
■ The retention time will only be applied for read-only database virtual copy.
■ The retention time can be set during RM-O configuration time ( vcdba_config ) per
database as a policy or during virtual copy creation time ( vcdba_create or
vcdba_rsync ).
■ The retention time set during configuration time serves as the default value all virtual
copies created thereafter.
■ The retention time can also be specified during a virtual copy creation to overwrite the
retention value set during the RM configuration.
■ The retention time can be modified but it can not be lower than the original setting.
■ The retention time can be specified in hours or days.
■ The minimum value for retention time is 0 hour and the maximum value is 43800 hours
(1825 days or 5 years).
■ The retention time can be set to 0 indicating that a database virtual copy has no retention
time and can be removed immediately.
