Subject [jira] Commented: (AMQ-892) Allow the JMX RMI server port to be hard set
Date Wed, 23 Aug 2006 18:44:23 GMT

John Heitmann commented on AMQ-892:
-----------------------------------

There are at least 2 unfortunate issues with the out-of-the-box 1.5 JMX config: the rmi registry
isn't able to use a secure transport, and the rmi server port is not able to be fixed. My
patch addresses the second, and I think you're right in that it's better to use the normal
jmx properties config rather than the xbean xml.

I'll redo this patch and mimic an out-of-the-box agent as described by one of the JMX developers
here: http://blogs.sun.com/roller/page/lmalventosa/20060602

That will have the nice benefit of also allowing a secure registry, which is something my
group will need shortly anyway.

> 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.
