IBM i Data/Application Server
From an IBM i command entry (CALL QCMD), use the WRKACTJOB command to verify that the LANSA Listener subsystem is active.
If the subsystem is not active, start the subsystem. If there are no jobs in the subsystem, then the Listener is not configured properly.
Windows Data/Application Server
From the Control Panel, Administrative Tools folder, use the Services icon to start the Microsoft Management Console to display the list of services.
If the listener (LCONNECT Services) is not started, use the right click context menu to start the service.
