Resynchronizing the snapshot to your database
When you have finished using a clone database or want to refresh it, you can
resynchronize it with the original database. This is also known as refreshing the
snapshot volume or merging the split snapshot image back to the current database
image. After resynchronizing, the snapshot can be retaken for backup or
decision-support purposes.
There are two choices when resynchronizing the data in a volume:
■ Resynchronizing the snapshot from the original volume.
■ Resynchronizing the original volume from the snapshot. This choice is known
as reverse resynchronization. Reverse resynchronization may be necessary
to restore a corrupted database and is usually much quicker than using
alternative approaches such as full restoration from backup media.
Reverse resynchronization is not supported in Oracle RAC configurations.
Before resynchroninzing the snapshot to your database, make sure the following
conditions are met:
■ You must be logged in as the Oracle database administrator.
■ Before you can resynchronize the snapshot image, you must
validate a snapplan and create the snapshot.
See “Summary of database snapshot steps” on page 243.
See “Validating a snapplan (dbed_vmchecksnap)” on page 255.
See “Creating a snapshot (dbed_vmsnap)” on page 260.
■ If a clone database has been created, shut it down and unmount
the file systems using the dbed_vmclonedb -o
umountcommand. This command also deports the disk group.
See “Shutting down the clone database and unmounting file
systems” on page 272.
