That's probably because they have massive amounts of memory installed. Unfortunately, we don't. I can't find any Oracle experts who know how to tune the memory requirements... ugh. In fact, the one's I have spoken to don't know if it's even possible. Thanks for your response.

I would think that you can tune the size of Oracle, probably dominated by the size of the SGA, even before you install/configure. unless there is something new Oracle is doing. Customers have run multiple instances of Oracle in a single Solaris instance, even without zones. I am not a DBA, otherwise I would offer tuning parameters.
