Table 13-1
Parameter values for dbed_vmchecksnap (continued)
ValueParameter
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.
