That's the first time I see a lady say that. I thought it was a
consolation of us, middle-aged, chubby DBA males. Joking aside,
the buffer cache should be increased using the same principle
as for everything else: you increase the buffer size when you start
seeing free buffer waits in your V$SYSTEM_EVENT. The basic principle
of the event-based tuning methodology is to try fixing that what
sessions are actually waiting for, instead of computing BCHR,
horoscope or your personal lucky number.
