I should also add the patchadd -d didn't work either, that is way I
tried the pkgadd

 #patchadd 109503-12

Checking installed patches...
One or more patch packages included in
109503-12 are not installed on this system.

Patchadd is terminating.

Hi All,

Sorry for not getting the chance to summerize. By default with Solaris
scheduling, my simulation CAD jobs will bind to a one cpu per job since
they are not multi-threaded. It ultizes that cpu to the fullest. There
is a command under Solaris that creates and manages the processor sets

Psrset would be more ideal in a case where there's four or more
processors. I can then setup a certain amount of cpu's for CAD jobs, but
in my case I only have dual processors and it wouldn't make sense to set
this up.

My question pertains to Sun CPU in general. I was unable to find
documents about this and I thought maybe someone here would know.

In a case where a system has dual cpu's, by default will it allocate all
the necessary process power to a application that is cpu intensive. In
other words, will it only use one of the two cpu's or will it use both
at the same time. I have noticed on all of my machines (V210)  which
runs CAD simulations has consistent of about 50% per job and 100% with
two jobs running. What are the default cpu settings on these servers and
solaris 8?
Would it be possible to utilize most of the cpu on the first job that
starts making it finish at a faster time?
