Rollback to Undo in a RAC env.

Rollback to Undo in a RAC env.

Hi All,

I am planning to covert the undo management from MANUAL to AUTO in a RAC
environment with 2 nodes.

My question is, do I need to shutdown both the instances for doing this or
can I change this parameter for 1 instance at a time. Can oracle mount 2
different instances with different UNDO management at a given point of time?

Last time when I upgraded the compatible parameter to 9200 I tried it one by
one first and I got the error message ORA-1105 (See ORA-1105.ora-code.com) as one instance was mounted
with compatible parameter 817 and I was trying to mount the other one with
compatible parameter 9200.

Also pls advise if any type of performance problems has been observed with
AUM.

Regards
