You can have the managed recovery running while database is open in READ ONLY
mode. Why do you want to take it from OPEN mode to MOUNT mode?

For those of you who switch your standby db between read-only and recovery mode
(non active data guard), how do you manage it?

I've in the process of configuring a reporting database as a standby db, and I
*think* I'm going to have to have a script that does 2 things (or 2 scripts).

1 - end recovery mode/open the db read-only during business hours
2 - close the db and put it back in recovery mode

I'm wondering about the "best" way to accomplish item #2. If there are users
connected to the DB, I have to kill those sessions *if* I want to do an "alter
database close". Should I just scratch that idea and do a shutdown abort on
the standby and reopen it?

I'm basically curious how other people are managing the switch between
read-only and recovery modes and if you're killing sessions or just shutting
down the db to put it back in recovery mode?

Thanks,
Chris
