Before a database is opened, the control file is read to determine whether the database is in a valid state to use. A control file is updated continuously by the Oracle server during database use, so it must be available for writing whenever the database is open. The information in the control file can be modified only by the Oracle server; no database administrator or end user can edit the control file....

Cross Checks of RMAN Backups and Copies Performing a cross check provides you with a way to ensure that data about backup sets and image copies in the RMAN repository is synchronized with corresponding data on disk or in the media management catalog. You can use the LIST command to obtain a report of the backups and copies that you have made and then use the CROSSCHECK command to check that these files still exist. If RMAN cannot find a file, it updates the repository records to EXPIRED. You can determine which files are marked EXPIRED by issuing a LIST EXPIRED command....

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.
