Since this is all running in one partition, about the only way I can think
of is to put a monitor on the system that whenever the Tomcat jobs spike
over a certain percentage of CPU for a specified period of time, it drops
the priority of those jobs to over 50. A CL using some APIs or Management
Central could do that for you.

What OS version?

I'm running Tomcat 5.5 directly on the IBM i. Periodically when running
some code the CPU spikes to 99.9%. We suspect it might be some infinite
loops in certain cases and we are analyzing that.

Tomcat is started from a CL command which calls the

How can I LIMIT the amount of CPU that Tomcat is allowed so it doesn't
degrade performance for the other system users?

Thanks, Paul Holm
