Be aware of "memory throttling" that may be *incorrectly* based on RSS
(Resident Set Size). What happened during a test long ago was this
(don't have the details now): A Sol 10 box set up with zones and some
kind of memory throttling severely affected DB Server performance as
it did not understand the presence of shared memory (SGA) and counted
the RSS of all processes, which was incorrect. We basically had to
switch off memory throttling. Apparently, there was an OS patch or
level which fixed this, but I left before we could upgrade...
