Restoring and recovering data: an overview

Reconstructing the contents of all or part of a database from a backup typically involves two phases: Restore and Recovery. Restoring is the process of retrieving a copy of the datafile from a backup. Recovery is the process of reapplying changes to the file since the backup from the archived and online redo logs, to bring the database to a desired SCN — typically the present, or the point of failure.

Based on your backup method, follow the instructions in the relevant topic for successfully performing data restoration using Plug‑in for Oracle.

Understanding User Managed recovery

When a User Managed backup strategy has been implemented, you must manage the recovery process. This process includes the following tasks:

•
Determining what to recover.
•
Restoring the needed files with the plug-in.
•
Performing the recovery process manually outside the plug-in by issuing a series of SQL*Plus commands.

The following topics provide an overview of the User Managed recovery process. For more information, see About User-Managed Restore Operation in the Oracle Database Backup and Recovery Advanced User’s Guide or to Performing User-Managed Backup and Recovery in the Oracle Database Backup and Recovery User’s Guide.

•
Determining which datafiles require recovery
•
Recovering datafiles and archive logs
•
Restoring Control Files

Determining which datafiles require recovery

When a media failure or data corruption has occurred, you can use the following SQL*Plus query to determine which datafiles need recovery. This command works only when the database is in an OPEN state:

SELECT FILE#, ERROR, ONLINE_STATUS, CHANGE#, TIME FROM V$RECOVER_FILE;
