Red Hat Summit第9章 Installing and running the headless Decision Manager controller
You can configure KIE Server to run in managed or unmanaged mode. If KIE Server is unmanaged, you must manually create and maintain KIE containers (deployment units). If KIE Server is managed, the Decision Manager controller manages the KIE Server configuration and you interact with the Decision Manager controller to create and maintain KIE containers.
Business Central has an embedded Decision Manager controller. If you install Business Central, use the Execution Server page to create and maintain KIE containers. If you want to automate KIE Server management without Business Central, you can use the headless Decision Manager controller.
9.1. Using the installer to configure KIE Server with the Decision Manager controller
KIE Server can be managed by the Decision Manager controller or it can be unmanaged. If KIE Server is unmanaged, you must manually create and maintain KIE containers (deployment units). If KIE Server is managed, the Decision Manager controller manages the KIE Server configuration and you interact with the Decision Manager controller to create and maintain KIE containers.
The Decision Manager controller is integrated with Business Central. If you install Business Central, you can use the Execution Server page in Business Central to interact with the Decision Manager controller.
You can use the installer in interactive or CLI mode to install Business Central and KIE Server, and then configure KIE Server with the Decision Manager controller.
