Home -> Community -> Mailing Lists -> Oracle-L -> Re: Buffer cache hit very low...!!!
firstly you are probably using db_cache_size new in 9i.
Also why are you still using ratios? that went out with the dinosaurs. Its
all about the wait interface now, find the problem which are causing your
biggest waits and fix them
generally ignore the ratios
