Config

Posted By: BRIAN FOSTER
Date: Friday, 17 September 2010, at 3:45 p.m.

I am doing an intial tune for a new instance of 11.5 64bit. All of our previous instances have been 32bit so I am unsure about my current shared
memory config... do I have too many buffers? I am also wondering whether I can safely add 1 or more CPU VP's.
The stats seem pretty good to me but I guess I expected more oomph (upgrading from 9.4 32 bit on 5 year old metal).
Any suggestions greatly appreciated!
