Don and Harvinder, I recommend you both take a look at v$db_cache_advice, your wait events (from statspack, AWR, or v$session_event and v$system_event) and even the old buffer hit ratio and then after taking all that into account, make an informed decision based on your findings rather than sizing your SGA/buffer cache based on how much RAM you have. The question asked is analagous to asking:

"My car can go 180mph, how fast should I drive?"

Regards,
Brandon
