A power user accidentally updates all the rows in your production table. But no one knows about it until the next day. What do you do? Yes, you have database backups (you do, don’t you?) and other safeguards in place. But bad things still happen to good databases. Is there a recovery approach other than restoring from backup, and then rolling the right transactions forward? Toad for Oracle has a little-known ability to ”mine” Oracle’s re-do logs.
