Re: SOFT PARSE RATIO?

Here are a few indications, which I believe also were to be found in 7:

• Parse/elapsed time CPU substantial part of CPU used by this session
• parse count (almost) as large as execute count
• latch free wait time high compared to CPU used by this session and the latches really hit are library cache and shared pool

Thanks, Bjørn.
