Introduction
Controllers are used to orchestrate Agents that execute jobs:
- A Controller is assigned any number of Agents.
- One or more Controllers can be registered with a single JOC Cockpit instance.
Controllers can be clustered for high-availability, for details about the architecture see JS7 - Controller Cluster.
Controller clustering is subject to the agreements of the JS7 - License:
- Use of Standalone Controllers:
- available to Open Source License holders and to commercial license holders.
- Use of Controller Clusters:
- available to commercial license holders,
- for details see JS7 - Management of Controller Clusters.
Manage Standalone Controllers
The JS7 - Controller Installation On Premises and JS7 - Controller Installation for Containers articles explain the installation of Standalone Controllers.
The icon in the JOC Cockpit main menu is used to select the Manage Controllers/Agents view:
This brings forward the following view:
- The view is grouped in Controllers (indicated by testsuite and standalone).
- Separate lists of Standalone Agents and Cluster Agents are displayed for each Controller.
Add Standalone Controller
Users can add a Standalone Controller by clicking on the New Controller button in the right hand upper corner.
This brings forward the following popup window:
Explanation:
- Title: An individual description that can be searched for.
- URL: The protocol HTTP or HTTPS, host name or IP address and port with which the Controller can be accessed from the JOC Cockpit.
- Test Connection: It is recommended that the connection between the JOC Cockpit and the Controller is tested.
- Users should note that firewalls can block access from the JOC Cockpit to a Controller.
- Use of a Proxy Service might require updating the URL.
Delete Standalone Controller
With deletion of a Controller, all Agents will removed from the Controller and from the JOC Cockpit inventory.
- Before deleting the Controller from the JOC Cockpit inventory:
- Any Agents registered with the Controller should be shutdown and their journals should be removed:
- Agents can act autonomously and might continue to execute workflows for which orders are still available.
- Agents' journals are located in the
state
sub-directory of their configuration directory.
- The Controller instance should be shutdown and its journal should be removed:
- Controllers act independently of the JOC Cockpit and maintain network connections to Agents.
- The Controller's journal is located in the
state
sub-directory of its configuration directory.
- Any Agents registered with the Controller should be shutdown and their journals should be removed:
- Deletion of a Controller does not remove workflows and other scheduling objects from the JOC Cockpit inventory.
- Scheduling objects can be deployed to any connected Controller.
