Retiring, March 2020 - sorry, you have missed our final public course.
The Coronavirus situation has lead us to suspend public training - which was on the cards anyway, with no plans to resume

Please ask about private 'maintenance' training for Python, Tcl, Perl, PHP, Lua, etc
Happily continuing private consultancy / programming work
 
Connecting jconsole remotely - the principles

BEWARE - this first is a "shows you how" and is insecure ... I am doing the demo this way because the security requirements add various issues that would complicate the first demonstration of principle.

1. Set up your SERVER to allow jmx remote connections on an otherwise unused port - we have done this by changing the Java options in the catalina.sh script - around line 188 in version 6.0.18 (ahead of the comment shown below) I added 2 lines:

JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=9876"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.authenticate=false"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.ssl=false"
# ----- Execute The Requested Command --------------------------


2. Restart the server via that catalina.sh script

3. Start the jconsole monitor

jconsole 192.168.200.215:9876

Now ... you should go back and add authenticated users ... lots of instructions available - here are some URLs to start you!

If you want to try out this (and all the other Tomcat stuff) with us ... have a look at out Apache httpd / Tomcat course ... you may want to ask for an "extra day" too if you're wanting to go into the more advanced topics in detail.
