clone rather than from the primary database to avoid introducing additional
burdens on the production database.
A clone database can also serve as a valid backup of the primary database.
See “Backing up the database from snapshot volumes (dbed_vmclonedb)”
on page 177.
You can also back up the primary database to tape using snapshot volumes.
The resynchronization functionality of Database FlashSnap allows you to quickly
refresh the clone database with up-to-date information from the primary database.
Reducing the time taken to update decision-support data also lets you generate
analysis reports more frequently.
Using Database FlashSnap to clone a database
In a same-node configuration, the dbed_vmclonedb command creates a clone
database on the same host. The command can also be used to shut down the clone
database and unmount its file systems. When creating or unmounting the clone
database in a same-node configuration, -r relocate_path is required so that the
clone database’s file systems use different mount points than those used by the
primary database.
When used in an off-host configuration, the dbed_vmclonedb command imports
the snapshot disk groups, mounts the file systems on the snapshot, and starts a
clone database. It can also reverse the process by shutting down the clone database,
unmounting the file systems, and deporting the snapshot disk group.
Warning: When creating a clone database, all Storage Checkpoints in the original
database are discarded.
