We recently purchased couple of T5200 from Sun. We have Java J2EE
Application server (WebLogic) running on them and the OS is Solaris

5200 has 64 threads (which I think is overkill), is it possible to
break down 64 threads such that the OS gets 16 and each of the
WebLogic instances gets 12 (so basically 16+12+12+12+12) ?

I have read about processor sets and containers but I am note very
clear on the implementation. Not sure what is the right way to
approach this problem. I just want input from others to see what
approach they have taken with this setup.

Thanks,

The answer really depends on your requirements, with the solution
often using a combination of features. I prefer not to use processor
sets, because of the potential for wasted CPU cycles. Using the fair
share scheduler (FSS), you can assign CPU shares to projects and
zones. FSS will make all CPU cycles available to any process on the
system as long as there is no resource contention. Once there IS
resource contention, FSS kicks in to keep processes in check according
to the assigned number of shares.
