This file is created at database creation time. It is updated automatically when backup
or restore
operations occur on the database, or on a table space. Table space operations, such as, creation
, quiesce
, rename
, or drop
, among others, also will have an impact on this file.
In our recipe, we will deliberately corrupt a history file and recover using an existing backup.
Please use a sandbox environment to duplicate this experience. Allow for the downtime to restart the instance.
We will corrupt the recovery history file by copying something else into this file. We already made a backup, so we're fine. Perhaps you would like to make a precautionary copy of this file first.
