Admin-GUI, JMX and RMI ports
« on: September 01, 2011, 01:54:51 PM »


I would like to understand how the admin gui "talks" to the server(s) and node(s).

Who listens and who connects to the JMX and RMI ports that are configured in the Server and Node configuration files? What kind of information is exchanged?

for testing purposes, I have an application, a server and the admin gui running on my local PC.
One node is running in a remote environment that can only be reached via a tunnel.
I created two tunnes from the remote node to my server node.
The node is able to connect to the server.

I can see the remote node and the local server in the admin gui. But the remote node in the admin gui is colored in red and node/exec-status are both "UNKNOWN".

I guess I have to create tunnels for the JMX ports, too - but which and from where to where?

Best regards,

Hello Bernd,

Both nodes ansd servers listen to the JMX and RMI ports. The RMI port is only used internally by each node and server, as this is the port for an in-JVM RMI registry.
The admin console will only connect to the JMX port and does not know about the RMI one, so the JMX port is the one you would need a tunnel for.

I hope this clarifies.
