Chapter 10. Managed KIE Server

A managed instance requires an available Decision Manager controller to start the KIE Server.

A Decision Manager controller manages the KIE Server configuration in a centralized way. Each Decision Manager controller can manage multiple configurations at once, and there can be multiple Decision Manager controllers in the environment. Managed KIE Server can be configured with a list of Decision Manager controllers, but will only connect to one at a time.

Important

All Decision Manager controllers should be synchronized to ensure that the same set of configuration is provided to the server, regardless of the Decision Manager controller to which it connects.

When the KIE Server is configured with a list of Decision Manager controllers, it will attempt to connect to each of them at startup until a connection is successfully established with one of them. If a connection cannot be established, the server will not start, even if there is a local storage available with configuration. This ensures consistency and prevents the server from running with redundant configuration.

Note

To run the KIE Server in standalone mode without connecting to Decision Manager controllers, see Chapter 11, Unmanaged KIE Server.
