This indicates that you are using about 2 CPUs because you are using threads.

If you have glance, you can check detailed memory utilization.

Since this is java, I'm not sure what you can do about CPU utilization?

Basic "top" utility has an option to show which processes a multi-threaded. JAVA is a multi-threaded application -- it is a "virtual machine" that runs build once run anywhere code. As such, being a multi-threaded binary -- it will have lots of LWPs (light weight processes" that can run on different CPUs -- hence top (and other tools like GlancePlus) shows that single WebLogic JAVA process as more thna 100%  CPU -- meaning it uses more than 1 CPU.

 

Do a man on "top" or find a good manual - it has lots of nice and powerful options to drill down on a process use of threads, cpus, memory and even I/O.

Not on HP-UX.  :-(

Not top.  Perhaps you are thinking about glance/gpm?
