  • Restoration and Datafile Media Recovery Using RMAN RMAN automates the procedure for restoring files. When you issue the RESTORE command, RMAN uses a server session to restore the correct backups and copies. The RMAN repository is used to select the best available backup set or image copies to use in the restoration. By default, RMAN does not restore a file if the file is already in the correct place and its header contains the correct information. In releases before Oracle9i, the files were always restored.
