Guys,
My database gives me the following observations
Dictionary misses - 9170
Dictionary hits - 147797
Library cache get hit ratio - 53.45
Parse to execute ratio - 89.35
Do you fine these normal? If not then what should I do to rectify these
Thanks
- Das

1. Performance tuning numbers make sense as percentage, not by numbers themselves.
2. The library cache hit ration way too low - tune the SGA -
3. There are plenty of resources on tuning SGA - I am sure you can find them here.
