ARCHIVELOG_DEST Specifies the full path of the archive logs.
There are several archive log destinations that can be used for
database recovery if you are multiplexing the archive logs. You
must specify which archive log destination to use.
It is recommended that you have the archive log destination on a
separate volume if SNAPSHOT_ARCHIVE_LOG is yes.
SNAPSHOT_ARCHIVE_LOG yes or no
Specifies whether to create a snapshot of the archive log volumes.
Specify yes to split the archive log volume mirrors and deport
them to the secondary host. When using the Oracle remote archive
log destination feature to send the archive logs to the secondary
host, you can specify no to save some space.
Because the archive logs may not always be delivered to the
secondary host reliably, it is recommended that you specify yes.
SNAPSHOT_MODE online or offline or instant
Specifies whether the database snapshot should be online, offline,
or instant.
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_PLAN_FOR The default value is database and cannot be changed.
Specifies the database object for which you want to create a
snapshot.
SNAPSHOT_PLEX_TAG 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.
