 Does Sun have any tools because tools like top and prstat don't give you 
 a clue to how much memory is really available to a zone.


Memory caps are super useful, but they do have a few issues. The
biggest issue is that shared memory is not accounted for properly, so
processes that use shared memory can suck up more memory that the
amount configured in the memory cap. The second issue is that you
can’t use memory caps in the global zone to limit how much memory is
used in a local zone. Both of these issues are being worked on by Sun
(I once read something, I cannot verify this).

See docs.sun.com - maybe.

Thanks Martin,
are you saying you can't use the rcapd in the global to limit memory via the 
FSS in the non-global zone?

What is a good way to test to see if your cpu is really capping correctly?
