Q - You have a backup from two days ago. It is discovered that corruption was introduced today at 6:30 P.M. You perform an incomplete recovery of the database to 6:25 P.M. before the corruption. One day later you have a media failure, and you need to recover but you only have the same backup that was used to perform an incomplete recovery prior to the corruption. What will happen to the recovery attempt for the media failure?
A - The media recovery will be successful because you can perform a RESETLOGS to recover from an incomplete recovery to a new point-in-time greater than the RESETLOGS operation.
With 10g, you can now recover through an incomplete recovery, which uses RESETLOGS to open the database. In previous Oracle versions, you had to take a backup immediately following an incomplete recovery, because the redo log sequences got reset, making the backup unusable.
