Subject [jira] Commented: (AMQ-892) Allow the JMX RMI server port to be hard set
Date Wed, 23 Aug 2006 18:18:23 GMT
    [ https://issues.apache.org/activemq/browse/AMQ-892?page=comments#action_36831 ] 
            
Bruce Snyder commented on AMQ-892:
----------------------------------

The JMX RMI port can be set in ActiveMQ 4.x using the JMX system properties. See the [How
can I monitor ActiveMQ? page|http://activemq.org/site/how-can-i-monitor-activemq.html#HowcanImonitorActiveMQ-AdvancedJMXConfiguration]
under the Advanced JMX Configuration heading. If the com.sun.management.jmxremote.port system
property is set within the SUNJMX environment variable, the ActiveMQ start script will pick
it up and pass it to the JVM.

> When debugging a broker over the firewall with JMX it's often necessary to use ssh tunneling.
JMX uses 2 ports. The RMI registry port is what is typically configured, but JMX also runs
an RMI server on a different port-- one that's typically chosen randomly. When you're ssh
tunneling you need to know what ports to tunnel to a priori so this is no good.
> This patch adds a setting to allow the RMI server port to be set in addition to the registry
port. This is what it looks like in xml:
>     <managementContext connectorPort="11099" rmiServerPort="11119" jmxDomainName="org.apache.activemq"/>
> Also I snuck in a one-liner change that will create the connector if the user configured
jmx. This seems like the right thing to do, but my JMX experience is pretty limited so it
could break in something like Tomcat. Please take a close look at that line before applying.
