I'm still kinda lost. Okay, I created a standby controlfile and I shutdown my primary database. After shutdown I backup the primary database. I copy the backup files and the standby to another hard disk over the network. Then I startup the standby database and mount standby over the network. Once the standby is mounted, I can't seem to mount the primary database at the same time. How would I startup the primary database while the standby is up?

thanx
