3057 is not a managed VM.

[gshekar]

Hi,

I want to monitor and manage the JBoss using JConsole. For this I downloaded jboss 4.0.1 and started it with JDK1.5 with the following java options "-Dcom.sun.management.jmxremote" in run.conf.

But I am getting "3057 is not a managed VM." error while starting jconsole with jboss PID. Please help.

[root@linuxpoc bin]# ps -ef | grep jboss
root 3030 1 0 01:21 ? 00:00:00 /bin/sh /usr/local/jboss-4.0.1RC1/bin/run.sh
root 3057 3030 1 01:21 ? 00:08:17 /usr/java/jdk1.5.0/jre/bin/java -server -Dprogram.name=run.sh -Djava.endorsed.dirs=/usr/local/jboss-4.0.1RC1/lib/endorsed -classpath /usr/local/jboss-4.0.1RC1/bin/run.jar:/usr/java/jdk1.5.0/jre/lib/tools.jar org.jboss.Main
root 4883 31994 0 10:42 pts/0 00:00:00 grep jboss

[root@linuxpoc bin]# ./jconsole 3057

Jboss 4 is built on JDK 1.4.x and uses JMX 1.2 so it is remotable already.

Only recently is JMX standard in JDK 1.5.

Also use MC4J pretty good open source JMX console.

So you dont have to start JMX through the VM.

Also it seems that Java 5 breaks some thing in Jboss and other application in general...
