The Database FlashSnap feature consists of three commands:
dbed_vmchecksnap (used on the primary host)
Creates and validates the snapshot plan used to create a snapshot image of an Oracle database. You can also use dbed_vmchecksnap to copy, list, or remove a snapplan or make sure the storage is configured properly for the task. dbed_vmchecksnap is also used on the secondary host to list the snapplan.
dbed_vmsnap (used on the primary host)
Creates a snapshot image of an Oracle database by splitting the mirror volumes used by the database. You can also use dbed_vmsnap to resynchronize snapshot volumes with their original volumes. The command also allows you to resynchronize the original volumes from the data in the snapshot volumes, which is useful if the original volumes become corrupted. Resynchronizing the original volumes from the snapshot volumes is known as reverse resynchronization.
Note
Snapplan creation and validation is only supported on CVM master node.
dbed_vmclonedb (used on the primary or secondary host)
Mounts and starts a clone database using snapshot volumes. It can also shut down a clone database and deport its volumes, as well as restart a clone database that has been shut down. The snapshot image can be brought up on the same host running the primary database or on a secondary host.
Note
dbed_vmclonedb does not support instant snapshot for database cloning.
All of these commands can be executed by the Oracle database administrator and do not require superuser (root) privileges.
Note
Database FlashSnap operations can be executed from the command-line.
