Purpose

After a crash or errors, you can restore a database instance or reset it to an earlier status by importing data backups and log backups from a backup medium.

Prerequisites

As any log entries that still exist in the log area are imported first, the database instance may have to be initialized before the actual recovery operation to force the deletion of the log entries in the log area. You can then import the required backups.

Process Flow

You use the Database Manager for the recovery.

...

       1.      Import a complete data backup. You can import data backups from a group of parallel backup media to reduce the recovery time.

       2.      If necessary, also import incremental data backups, log backups and any log entries that still exist from the log area.

       3.      If necessary, restore any indices that were damaged.
