Use the CREATE RESTORE POINT statement to create a restore point, which is a name associated with an SCN of the database corresponding to the time of the creation of the restore point. A restore point can be used to flash a table or the database back to the time of creation of the restore point without the need to determine the SCN or timestamp.
There are two types of restore point:
• Guaranteed restore points: A guaranteed restore point enables you to flash the database back to the restore point regardless of the DB_FLASHBACK_RETENTION_TARGET initialization parameter setting.
Guaranteed restore points must be dropped explicitly by the user using the DROP RESTORE POINT statement. They do not age out.
• Normal restore points: A normal restore point enables you to flash the database back to a restore point within the time period determined by the DB_FLASHBACK_RETENTION_TARGET initialization parameter. You can explicitly drop a normal restore point using the DROP RESTORE POINT statement.
