Using Flashback Database and a physical standby database, you can configure a temporary clone database for testing and reporting. The temporary clone can later be resynchronized with the primary database.
Flashback Database uses Flashback logs to access previous versions of data blocks and also uses some data in the archived redo logs. To have the option of using Flashback Database to repair your database, you must have configured the database to generate Flashback logs as explained in "Configuring Recovery Settings".
Click Perform Whole Database Recovery page from the Perform Recovery page. You can then choose to flashback a database. Click Help for more information about using flashback database.
Flashback Database lets you quickly recover an Oracle database to a previous time to correct problems caused by logical data corruptions or user errors. Flashback Database is not true media recovery, because it does not restore physical files. But Flashback Database, using RMAN and SQL FLASHBACK DATABASE commands, can be preferable to using the RESTORE and RECOVER commands in some cases, because it is easier, finishes sooner, and does not require restoring the whole database.
Flashback Database Restore the entire database to a specific point-in-time, using Oracle-optimized flashback logs, rather than via backups and forward recovery.
The flash recovery area must be set to enable flashback logging. When using flashback logs, you may recover your entire database to a prior point in time without restoring files. Flashback is the preferred point in time recovery method in the recovery wizard when appropriate.
Note: Oracle Flashback Database does not recover missing datafiles.
