Resynchronizing a database to a snapshot
Resynchronizing your database to a snapshot, also known as reverse
resynchronization, reverts your database to a snapshot. Use this option if your
database becomes corrupted and you need to restore your database to a previous
point-in-time.
■ You must be logged in as the Oracle database administrator.
■ You must shut down the primary database and the clone database;
also, unmount the file systems.
Prerequisites
■ See the dbed_vmsnap(1M) manual page for more information.Usage notes
To resynchronize a database to a snapshot
1
Click a snapplan, located under the Snapplans icon, in the object tree. (You
may need to expand the tree view to find the icon.)
2
Access the Reverse Resync wizard.
See “Accessing FlashSnap tasks in the Java GUI” on page 28.
See “Accessing database tasks in the Web GUI” on page 35.
3
Verify the Oracle SID and snapplan information. These are read-only fields.
4
Click the Begin button, then click Finish to start the reverse resynchronization
process. To view details, click the Show details checkbox. The details are
displayed in a pop-up window.
5
At the confirmation prompt, click Yes to continue.
The Begin option performs the following actions:
■ Imports the disk group that was deported from the secondary host and
joins it back to the original disk group.
■ Mounts the snapshot volumes.
■ Mounts the file systems that are configured for the primary database.
■ Brings up the database snapshot image as the primary database.
The primary database must be offline to perform this action.
6
If the begin action was successful, a confirmation message displays. Click
Show details to see the actions completed. When you are through, click OK
to continue.
7
Again, click the snapplan on which you want to perform the reverse
resynchronization.
