Re: Does an upgrade of the db version affect index organization or number of entries returned from an index in a query?

I am getting killed after upgrade to 9208 as well, excessive index scans is all i see. We are still looking but I have so far been unable to find the optimizer changes related to 9208 upgrade.

anyone have that link handy?
