Oracle Flash Recovery Area (FRA) is a directory that contains Oracle datafiles, archived redo logs, backup pieces, the control file, and image copies.
This backup has the advantages of automatic file management and quick recovery, but has the disadvantage of requiring more storage space than the database.
FRA can run out of space, so please schedule regular backups of the Flash Recovery Area to the backup media.
- Use a unique backup piece format to avoid conflicting backup piece names.
- The database must in ARCHIVELOG mode.
