CPU Utilization

[vishaldel]

Hi,

I am running an standalone JMS application using Message Listener on HP -UX server (B.11.00 U 9000/800 (ta)).

This application is taking lot of CPU time in my production
environment. While the same code takes very little CPU time in devl/model environment. I have verified all the app parameters, JDK, JMS verison, JBBC driver, DB version and everything is same.

And yes my application is not being used extensively. So I can say that the higher CPU utilization is not due to load of requests.

Does any one has any clue to resolve this.

Thanks
Vishal

Is dev/test the same O/S, patch level hardware (esp. same no. of processors).

Hi,

Now I have started getting this problem in Dev & Test environments also. I ran the JAVA code in Verbose:gc mode and found that JVM is running full GC after every second.
And simultaneously I am getting following JMS error
'MQJMS1016E an internal error has occurred. Failed to Redirect messages. OutofMemoryError'

Anyone has any clue???

Thanks
Vishal

have you had a look through the documentation for things such as required kernel changes and ulimit parameters?

I agreed with pete91z for you to verify the kernel parameters..
