Upgrade standby database
Hi,
In 10g, while upgrading a database which has one physical standby Oracle recommends the below process(high level steps)
First in standby:
1. stop all services & shut down all db instances running from the home
2. upgrade binaries
3. mount standby database
In Primary:
Repeat 1 & 2 steps then
3. execute rdbms upgrade scripts
4. enable log shipping
5. start managed recovery in standby
In this case I have to take the complete outage for application which is not possible for one of my applications. I am planning to follow the below steps to minimize application outage.
1. cancel managed recovery and open standby in read-only
2. route application traffic to standby db (application will have limited functionality which is okay)
3. stop services, shutdown db and upgrade primary database binaries and run rdbms scripts
4. start primary database and services
5. route application traffic back to primary database
6. upgrade standby database binaries
7. mount and start managed recovery in standby database
I would like to see some suggestions about the above approach. Appreciate your time.

I was thinking about doing the same thing.
Keep us posted.
Good luck!
