Table A-4
Snapplan parameters (continued)
ValueParameter
online or offline or instant
Specifies whether the database snapshot should be
online, offline, or instant.
Only online snapshot mode is supported by Veritas
Storage Foundation for Oracle RAC.
If the snapshot is created while the database is online,
the dbed_vmsnap command will put the tablespaces
into backup mode. After dbed_vmsnap finishes
creating the snapshot, it will take the tablespaces out
of backup mode, switch the log files to ensure that
the extra redo logs are archived, and create a
snapshot of the archived logs.
If the database if offline, it is not necessary to put the
tablespaces into backup mode.
If the snapshot mode is instant, a snapshot will be
taken regardless of whether the database is online
or offline. If it is online dbed_vmsnap will skip
putting the tablespace into backup mode.
Note: If SNAPSHOT_MODE is set to offline or
instant, a two-host configuration is required and
the -r relocate_path option is not allowed.
SNAPSHOT_MODE
The default value is database and cannot be changed.
Specifies the database object for which you want to
create a snapshot.
SNAPSHOT_PLAN_FOR
Specifies the name of the tag set to the plexes that
will be used by dbed_vmsnap to take the snapshot.
The dbed_vmchecksnap command will use this tag
name to search if all the volumes in the database have
the plexes with this tag name set.
By default,
SNAPSHOT_PLEX_TAG=dbed_flashsnap.
SNAPSHOT_PLEX_TAG
Specifies the snapshot volume prefix. Use this
variable to specify a prefix for the snapshot volumes
split from the primary disk group. A volume name
cannot be more than 32 characters.
