Veritas Storage Foundation for Oracle 5.0 Administrator's Guide, HP-UX 11i v3, Second Edition, December 2008

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.
