Hi,

I'm trying to get JMX active for my Tomcat server but do not succeed. In Netstat i do not see the port I defined for JMX. Since iseries is a bit of an outsider there is not much in the way of dicumentation i can find for, especially regarding the syntax of the java options.

This is what i have tried:

CATALINA_OPTS="$CATALINA_OPTS "-Dcom.sun.management.jmxremote
CATALINA_OPTS="$CATALINA_OPTS "-Dcom.sun.management.jmxremote.port=48009
CATALINA_OPTS="$CATALINA_OPTS "-Dcom.sun.management.jmxremote.ssl=false
CATALINA_OPTS="$CATALINA_OPTS "-Dcom.sun.management.jmxremote.authenticate=false

And this:
CATALINA_OPTS="$CATALINA_OPTS "-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=48009 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

Whatever I do, Tomcat starts, but not JMX

Does anyone know the correct syntax for these parameters in a iseries envrionment?

is the first Dcom.sun.management.jmxremote parameter necessary? Some sites omit it

Is there maybe a way to see why jmx does not start? I have tried everything both with jdk 1.4 as well as jdk 1.5

Thanks
Tom

Dear Tom,

That is precisely why I created Java-monitor. (http://java-monitor.com) It removes the need to deal with enabling JMX, getting it to work on a specific port range (you know JMX uses RMI, which uses dynamic port allocation, yes?) and the subsequent firewall nastiness.

Java-monitor builds on JMX, but connects to the mbean server directly and then uses web services to collect the samples. No firewall changes needed, no configuration.

It is sorta covered in the JavaRanch Style Guide.
