    Hit ratios doesn't show the overall database load but, gives SGA utilization before and after init parms changes which gives an idea of Memory usage upon increasing number of processes.

    The only one I believe in is Mr.H's 100% Hit Ratio on developers

    I dont believe in hit ratios anyways, seen many damn slow databases with 99% hit ratios, the funny thing is hit ratio is always 99% even the peeps who are in charge decrease or increase the SGA so they always think big is good hehehe

    Once I saw a guy put 4gb data block buffer, his argument was to achive e99% hit ratio, I decreased to 300mb and he asked, why you get 99% hit ratio too?

    Run some 10 F** queries 10 times a day you can see hit ratio shoot up 95+ ( I think, the guy whose argument and moto to achieve 99% hit ratio should be given noble prize )

    I should have been little clear in my posting(Hope its clear for JMac now), Anyway, I didn't say go by Hit ratios for Database Performance or databse load. I know, I had similar situations of poor database performance with 90+ hit ratios.

    Just to get relative comparision of where memory usage for the same database with same kinda queries running before and after incrementing processes. Simple and Dirty way of finding how resources(memory, cpu, i/o) utilized when number of processes(sessions) increased.
