Upgrade from 10g to 11g

edited Jul 3, 2014 5:00AM in Database Install/Upgrade/Opatch (MOSC) 6 commentsAnswered

I install a RAC 11gR2 (11.2.0.3) Database....Then I take RMAN backup of my 10g RAC DB and restore and recover and upgrade to new 11g RAC.

Now I have come to know there are performance problems....in New 11g RAC Database.

Some queries are running more time....

I also use same pfile as I was using in 10g RAC...

What to do?

Howdy, Stranger!
