• Problem: Assume that the JOC Cockpit uses a Controller registered as a Standalone Controller. If the same Controller is registered as a Controller Cluster member then the JOC Cockpit throws an error such as
  • JocObjectAlradyExistException: com.sos.joc.exceptions.JocObjectAlreadyExistExceptionJocObjectAlreadyExistException: Controller(s) with id 'controller' already exists exists 
  • This error message is available from the JOC Cockpit's log file too, e.g. from the JS7_JOC_DATA/logs/joc.log file, see JS7 - Log Files and Locations.
• Solution: It is not possible to register the same Controller twice, as a Standalone Controller and as a Controller cluster.

• Check that you have a license key ready as the clustering for Controllers is available for a commercial license, see JS7 - LicensingLicense.
• Verify that execution of workflows is completed with the Standalone Controller and that no orders are running.
• Remove the Standalone Controller from the JOC Cockpit GUI.
• Shutdown the Standalone Controller and remove the Controller's journal files in its JS7_OONTROLLER_DATA/Statestate directory.
• Follow the steps from the JS7 - Initial Operation for Controller Cluster article.
• Redeploy the scheduling objects such as workflows from JOC Cockpit to the Controller Cluster.

• Problem: Use of a Controller Cluster requires a license, see JS7 - LicensingLicense. It is not possible to configure a Controller Cluster without license keys being in place with both Controller instances. In case that the license is missing from a Controller instance while configuring the cluster the following error is raised:
  • js7.common.system.startup.JavaMain - No license for js7.controller.cluster js7cluster js7.base.problem.ProblemException$NoStackTrace: No license for js7.controller.cluster.
  • This error message is available from the Controller instance's log file too, e.g. from the JS7_CONTROLLER_DATA/logs/controller.log file, see JS7 - Log Files and Locations.
• Solution: Install both Controller instances with a license key, see JS7 - Controller Installation On Premises and JS7 - Controller Installation for Docker Containers. Alternatively add the license key as explained by the   JS7 - Initial Operation for Controller Cluster article. Find additional information from the JS7 - FAQ - How to apply a JS7 License Key article.
