The Database Manager supports the recovery of the database instance by restoring backups. You can recover either the last database state or an earlier one.

The Database Manager also supports the recovery of indexes and defective mirror log volumes.

Note

If the automatic log backup function was not activated before the recovery of the database instance started, this function is not automatically reactivated after the recovery.

To reactivate the log backup function, proceed as described under Activating the Automatic Log Backup.

Process Flow

You can usually use the Recovery Wizard to perform interactive recoveries of data. The Recovery Wizard proposes the optimal recovery strategy for your purposes. You can choose from the following procedures:

·        Restoring the Last Backup in the Backup History

·        Restoring a Backup from the Backup History

·        Restoring Without a Backup History

·        Continuing an Interrupted Recovery

·        Restoring with an Automatic Tape Loader

·        Restoring with External Backup Tools

If a recovery is not possible using the above procedures (for example, because the database instance was deleted), you have to initialize the database and then restore it. The initialization process makes this a much lengthier procedure. Use it only if absolutely necessary.

·        Restoring After Initializing a Database Instance

You can use the Database Manager GUI to restore indexes and mirrored volumes:

·        Restoring the Indexes After a Database Recovery

·        Restoring a Mirrored Log Volume
