more of an APP questions. basic oracle quesitons
1) how is a hot backup performed.
i am thinking it does 1 of 2 things.
1) it exports the db and then you backup the exported files.
OR
2) you just backup the files on disk as teh db is running.
i dont need to know HOW it is done. but just the basic concept of a hotbackup. i cant find it on oracle.com.
ie: if i have a db that is 5gb. do i need another 5gb mount point for the hotbackup? or do you need a predetermind amout of space for a hot backup.
