One point I haven't heard come up in this discussion. Most servers today are hooked to a SAN or at least a RAID set. These things have caches themselves, sometimes enormous. The hope is that this cache will augment the Oracle buffer cache. You may want to talk to your storage specialist. But you probably won't speak the same language. :-( Unfortunately storage people are trained to take an enterprise viewpoint, so sometimes think a single database isn't worth their attention.
