Backup files are discussed in Chapter 11, “Backing Up and Recovering Oracle Collaboration Suite”. If you attempt to perform recovery when no recovery is required, Oracle Database issues an error message.

Oracle Database automatically determines how long undo data should be preserved after the transaction has been committed based on queries running against the database. During this time, the undo data is said to be in the unexpired state. Oracle will keep the undo data in the unexpired state as long as needed by queries currently running against the database or as long as any low undo retention threshold (whichever is longer). Undo data is a good candidate for overwriting only when it is in the expired state. In order for changes to be rolled back or undone, Oracle makes a copy of the original data before modifying it.
