Table 13-1
Parameter values for dbed_vmchecksnap (continued)
ValueParameter
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_ARCHIVE_LOG
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. The
database must be shut down before creating an
offline snapshot.
If the database snapshot is instant,
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.
