What performance metrics are you seeing that indicated that either of
these (or any other) should be increased? What are your top 5 wait
events? While there are no rules of thumb, and compareing one db to
an unknown other is fraught with danger, your shared_pool_size is
already 5 times bigger than my largest one. I could easily be wrong,
but given the question and lack of additional information, I smell
hardware being thrown at an undiagnosed problem.
