Lesson 6: Configure the Listener

In this lesson, you configure the Listener by storing the Listener options in a text file, and then running dblsn with the file name specified at the command line.

♦  To configure the Listener
  1. Run the following command to synchronize with the MobiLink server and create the SIS_CarDealer_LP_DBLSN_REM.rid file:

    dbmlsync -c filedsn=SIS_CarDealer_LP_DBLSN_REM.dsn -ot dbmlsync.log -qc -e sa=on

    The Listener can use the $remote_id action variable to define a poll key, which the MobiLink server uses to identify the device. This variable is retrieved from the remote ID file, SIS_CarDealer_LP_DBLSN_REM.rid, which is created during the initial synchronization with the MobiLink server. You must synchronize with the MobiLink server to make use of the remote ID file.

  2. Create a text file mydblsn.txt with the following contents.

    # Verbosity level
    # Show notification messages in console and log
    # Truncate, then write output to dblsn.log
    -ot dblsn.log
    # Remote ID file (defining the scope of $remote_id)
    -r SIS_CarDealer_LP_DBLSN_REM.rid
    # Message handlers
    # Watch for a notification without action
    -l "poll_connect=tcpip(host=localhost);
    # Signal dbmlsync to launch, sync and then shutdown
    -l "poll_connect=tcpip(host=localhost);
        action='run dbmlsync.exe -c filedsn=SIS_CarDealer_LP_DBLSN_REM.dsn -ot dbmlsync.log -qc -e sa=on';"
    # Shutdown the listener
    -l "poll_connect=tcpip(host=localhost);
        action='DBLSN FULL SHUTDOWN';"
  3. Save the mydblsn.txt file.

  4. Start the Listener.

    At a command prompt, navigate to the directory of your Listener command file.

    Start the Listener by entering:

    dblsn @mydblsn.txt

    A window appears indicating the Listener is running.
