Each enabled IBM webMethods Cloud account should have an active listener on the on-premises Integration Server. The listener listens for requests from IBM webMethods Cloud to execute services on the on-premises Integration Server. To ensure that each enabled IBM webMethods Cloud account has an active listener, Integration Server uses a monitoring thread that executes at as specified interval. If the monitoring thread finds a listener that is not running, the monitoring thread attempts to start the listener. The watt.wmcloud.listeners.monitoringInterval server configuration parameter determines the interval at which the monitoring thread executes. The default value of the parameter is 300000 milliseconds (5 minutes).

Integration Server stops and restarts all on-premises account listeners whenever the Update Settings button on the webMethods Cloud > Tenant connections page is clicked.

When an account connection is disconnected or restored, Integration Server notifies the user through a notification in Integration Server Administrator followed by an email. Integration Server generates notifications for an active listener.

When you create an account, the on-premises Integration Server creates two listeners (request and response) for the account. Therefore, if an account is disconnected or reconnected, Integration Server generates two notifications per listener. Configure the hybrid activity notifications using the watt.server.hybridConnectivityAlert.notifications server configuration parameter and the recipients of the notification emails using the watt.server.hybridConnectivityAlert.toMailList server configuration parameter. Integration Server uses the email notification settings configured in Integration Server Administrator > Settings > Resources. The notifications are generated only for accounts with an active listener on the on-premises Integration Server. For more information, see the IBM webMethods Integration Server Administrator’s Guide.
