LGMapper Node Manager (LGMapperNM)

Overview

The LGMapper Node Manager (LGMapperNM) is a Windows Service used to control the lifetime of an LGMapper Server. The LGMapper Server is a DCOM server which continues running as long as there is at least one connected client. If all AlarmTracker clients disconnect, the LGMapper Server exits. If you want the LGMapper Server to run continuously, use the LGMapper Node Manager service to keep it running. The LGMapperNM also tries to check for proper operation of the LGMapper Server. If LGMapperNM detects that the server is hung or not operating properly, it attempts to stop the server and restart it.

Starting the LGMapper Node Manager

Windows NT

On a Windows NT machine, go to the Control Panel and double-click the Services icon. This displays the registered NT Services (Figure 5-1).

Figure 5-1 NT 4.0 Services - Starting LGMapperNM

If properly registered, the list contains the LGMapperNM and the LGArchiverNM services.

Start the LGMapperNM Service by selecting it and clicking Start (Figure 5-1). A new tray icon appears in the Windows NT task bar.

You can also configure the LGMapperNM service so that it vstarts up automatically when the machine boots. To do this, highlight the LGMapperNM service and click Startup. In the Startup Type group box, check Automatic in the Startup Type group box.


Note Due to a Windows NT bug, if you start the service automatically, the system tray icon may not appear when the system restarts. This should not be an issue with Windows 2000 servers.
