Gaja makes very good points about the importance of hit ratios but I don't think we should go 180 degrees the other way and abandon them all together. They certainly tell us something. They just shouldn't necessarily be a tuning goal. However, most of us are only seeing the hit ratio as of database startup. This is somewhat meaningless. If you are aware of your hit ratios as they look throughout the average day they become more meaningful when something is awry. I think the real misconception is "bad hit ratio = more memory" or "bad hit ratio = bad dba". This is what we need to clear up and bring some commen sense to. - Ethan

Yea, "hit ratios" are never important.

Ever.

For anything.
