RMAN Restore & Recover
Oracle RMAN Recovery involves two parts: restoring a physical backup and then performing recovery with the changes made to the database since the last backup. A media recovery is executed on the user's command, usually in response to media failure. In media recovery, online or archived redo logs can be used to make a restored backup current or to update it to a specific point in time.
Media recovery can restore the whole database, a tablespace or a datafile and recover them to a specified time. Whenever redo logs are used or a database is recovered to some non-current time, media recovery is being performed.
Use the RESTORE and RECOVER commands for RMAN restore and recovery of physical database files.
