Re: 9i Parsing Optimization

Without seeing the statement, I would say max_permutations. Your parse
elapse time consists of mostly cpu time, so that could be it. However it may
not be the (only) one.

Hi

I have TKPROFed some batch processes running in Oracle 8i. After upgraded
to 9i I monitored the same batch processes and I notice Parsing has been
reduced by 50% without changing any code.

Does anyone know what Optimization is this? I have not changed any
parameters. Only added automatic pga.


TIA
