A comment I picked up from Tom Kyte's Masterclass in Copenhagen last week was that there is an effective limit of 1GB to P_A_T - and although a single session is supposed to be allowed 5% of the P_A_T, you could get about 90MB. So there are some funny things going on in that area which still need fixing.
It's a bit tough for big systems, as I've found that the optimizer seems to be much smarter about memory user and access paths when P_A_T and W_S_P are set. What's the book about ?
