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?

Subject: How To Limit Tomcat CPU on IBM i
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 catalina400.sh
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
