“TO BEFORE RESETLOGS” Returns the database to its state including all changes up to the SCN of the most recent OPEN RESETLOGS.
Note: FLASHBACK DATABASE can only return the database to a point before the most recent OPEN RESETLOGS operation if your database has been upgraded to Oracle Database 10g Release 2 or later.
