Hi

>> Doing a manual GC at arbitrary times can be disruptive in that it suspends application threads for the duration.

Reason : We have a Production TOMCAT 5.5.23 where in CPU Utilization for JAVA is going 100% ,

This Tomcat needs to be restarted started every 12+ hrs

We suspect HP supported JDK1.6 bing the culprit for the same


with regards

For a  Production and Live version Tomcat, Can i hook
Jconsole via JMX on the tomcat and force GC process in
REMOTE Mode...
Is this permitted or not ?

Depends on what you mean by "permitted".  It certainly works, but it's probably 
not a good idea to push the button - let the JVM take care of GC, that's what it's good 
at.  Doing a manual GC at arbitrary times can be disruptive in that it suspends 
application threads for the duration.

If you're worried about the security aspects, don't configure JMX without 
authentication.
