Upgrade. Everything. Seriously.
client visual vm 1.3.5 O/s windows jdk :1.6.20
I need to use the Visual VM GC to monitor remote JVM's GC
activity.
Do you absolutely require Visual VM, or can you use any JMX client?
this requires the following
jstatd -J-Djava.rmi.server.hostname=192.168.4.32
-J-Djava.security.policy=/tmp/KARTHIK/jdk1.7.0_40/policy/tools.policy
Note
that you can connect via JMX without using jstatd. Do you really
need jstatd?
currently i need to execute this outside the TOMCAT env, but if
the same could be configured from within Catalina.sh
Can this be configured in catalina.sh ,if yes HOW ???
I've never used jstatd, but it seems like it should be run one-time on
a server hosting any number of JVM processes. I don't think you want
to run this kind of thing from catalina.sh, unless you have a
complicated procedure to check to see if it's already running, etc.
If you're going to run jstatd on your server, I would recommend that
you run it on startup using /etc/init.d or whatever and leave it
running. Or, even better, use another script to launch your Tomcat
instance: first, it checks for jstatd and runs it if necessary, and
then it calls catalina.sh. Now you call startup-my-jvm.sh instead of
catalina.sh.
If you must do it from catalina.sh, then please put it instead in
setenv.sh, because Tomcat upgrades won't conflict with whatever you
put in there.
