- A Troubleshooting SGeRAC
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.
5. You can now use the clone database to perform database backup and other off-host processing
work.
6. 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. depicts the
sequence of steps leading up to taking a snapshot using Database FlashSnap.
Figure 5-3 depicts the sequence of steps leading up to taking a snapshot using Database FlashSnap.
