Restarting, stopping, and viewing the status of MQ Connectivity by using the IBM Watson IoT Platform - Message Gateway Web UI

System administrators can view the status of the MQ Connectivity process, and restart and stop the process by using the Server Control page in the IBM® Watson IoT Platform - Message Gateway Web UI.

About this task

When the MQ Connectivity process is stopped, the durable subscriptions that are used to receive published messages remain active. Therefore, any messages that are published while the MQ Connectivity process is stopped are delivered as soon as the process is restarted. As the messages are buffered, the maximum messages limit of the destination mapping rules might be reached. This limit prevents publishers from sending any more messages. If you do not want this behavior, or if you are stopping the MQ Connectivity process for a long time, disable all the destination mapping rules before you stop the process.

You can view the status of the MQ Connectivity process, and restart and stop the process by using the IBM Watson IoT Platform - Message Gateway Web UI, or by using REST Administration APIs. For more information about using REST Administration APIs to view the status of the MQ Connectivity process, see Viewing the status of the MQ Connectivity process by using a REST Administration API. For more information about using REST Administration APIs to start, restart and stop the MQ Connectivity process, see Starting, restarting and stopping the MQ Connectivity process by using REST Administration APIs.

Procedure

  1. Go to the Server Control page by selecting Server Control from the Server menu.
  2. Check the status of the process in the Status field of the MQ Connectivity Service pane:
    • If the status is Running, the MQ Connectivity process is running.
    • If the status is Stopped, the MQ Connectivity process is not running.
  3. Choose an action from the MQ Connectivity Service pane:
    • To start the process, ensure that Enable MQ Connectivity check box is selected and click Start the service.

      This option is only available if the process is not running and the Enable MQ Connectivity check box is selected.

      If the process does not start, check the logs for messages. For more information about the log files, see Log files.

    • To stop the process, click Stop the service.

      This option is only available if the process is running.
