1.PURPOSE AND SCOPE
In this article, we are going to take user managed backup and try to restore it until spesific time.
2.PRACTICE
2.1. Lets start with backup side of user managed backup/restore.Before starting to copy tablespaces we need to changing the status of tablespaces.By the way you dont need to change the status of tablespaces like me by one by one, you can use “ALTER DATABASE BEGIN BACKUP;” command to take all of them backup mode.
