On the secondary host, use the dbed_vmclonedb command to create a clone
database using the disk group deported from the primary host.
The dbed_vmclonedb command imports the disk group that was deported
from the primary host, recovers the snapshot volumes, mounts the file
systems, recovers the database, and brings the database online. If the
secondary host is different, the database name can be same. 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.

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.
Figure 13-3 depicts the sequence of steps leading up to taking a snapshot using
Database FlashSnap.
