Unable to successfully reconfigure JON Agent to communicate with JON Server when hostname has changed

Solution Verified - Updated -

Issue

  • Originally the JON Server and 4 JON Agents were properly configured and working under in our environment. 
  • To test our build, we took VM images of the 4 nodes and modified the hostnames from dev-node.host.com to test-node.host.com
  • When the tester re-configured the Jon Agents using the new hostnames (using the --cleanconfig option), it appears that the old hostnames are still residing somewhere  because the JON agent log files show the JON Agent trying to access the JON Server at the old "dev" hostname. Hence, we are unable to get the JON Agent to communicate with the JON Server (even though they are on the same node!).
  • We really want to avoid having to do a complete reinstallation of the JON Server and JON Agents each time there is a change in hostname.

  • Could the old name be referenced in the database somewhere?
