Starting, stopping, restarting and viewing the status of the Eclipse Amlen server

You can restart, stop and view the status of the Eclipse Amlen server by using REST Administration APIs or by using the Amlen WebUI.

If you stop the Eclipse Amlen you can only start the server by using a Docker command or by using a systemctl command directly on the host OS. You cannot start the server by using a REST Administration API or by using the Amlen WebUI. Therefore, if you make a configuration change that requires a server restart you might want to use the REST API service restart command rather than stopping and starting the server, so that you maintain REST API access to the server process.

The Eclipse Amlen server status determines what actions can be carried out on the server. You can view the server status by using a REST Administration API, or by using the Amlen WebUI.
  • If the server status is Stopped, the server is not running. You can start the server.
  • If the server status is Running, the server is running. You can restart or stop the server. Stopping the server prevents all messaging.
  • If the server status is Maintenance, the server is in maintenance mode. For more information about maintenance mode, see Maintenance mode.
