On the secondary host, use the dbed_vmclonedb command to create a clone
database using the disk group deported from the primary host. For more
information:
See “Cloning a database (dbed_vmclonedb)” on page 181.
If the primary and secondary hosts specified in the snapplan are different,
the dbed_vmclonedb command takes the following actions:
■ Imports the disk group that was deported from the primary host
■ Recovers the snapshot volumes
■ Mounts the file systems
■ Recovers the database
■ Brings the database online with a different Oracle SID name than the
primary host.
You can use the -o recoverdb option to let dbed_vmclonedb perform an
automatic database recovery, or you can use the -o mountdb option to perform
your own point-in-time recovery and bring up the database manually. For a
point-in-time recovery, the snapshot mode must be online.
You can also create a clone on the primary host. Your snapplan settings
specify whether a clone should be created on the primary or secondary host.

You can now use the clone database to perform database backup and other
off-host processing work.

For single instance Oracle, the clone database can be used to reverse
resynchronize the original volume from the data in the snapshot, or can be
discarded by rejoining the snapshot volumes with the original volumes (that
is, by resynchronizing the snapshot volumes) for future use.

Tasks after creating a snapshot
There are many actions you can take after creating a snapshot of your database
using Database FlashSnap. You can create a clone of the database for backup and
off-host processing purposes. You can resynchronize the snapshot volumes with
the primary database.
For single instance Oracle, in the event of primary database failure, you can recover
it by reverse resynchronizing the snapshot volumes in the event of primary
database failure.
