jmx remote connection

[#1]

Hey,

I have alfresco 4.0 installed and try to connect from remote via jmx but it failed.
My client is JConsole, the URL I use looks like

service:jmx:rmi:///jndi/rmi://<hostname>:50500/alfresco/jmxrmi‍

Where <hostname> is the name of my host. The JMX user name and password are the defaults.
Unfortunately the connection failed. Could anybody help?

Are you trying to connect from the same machine or from a remote machine?

What JVM are you running?

And have you allowed JMX connections in the Java command line?

I'm trying to connect from a remote machine where Java 1.6.0_22 (64bit) is running.
The alfresco is an enterprise installation.

I added the following JMX setting to ${ALFRESCO_HOME}/tomcat/scripts/ctl.sh

-Dcom.sun.management.jmxremote.port=18086
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false‍‍‍

After adding these settings the connection with "JConsole" did not work.

i have same problem, i am using java 1.7 64bit on remote machine and i am trying to connect. it does not work "connection failed"

alfresco 4.0d running on centos 64bit with following settings
