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 -v2 # Show notification messages in console and log -m # Truncate, then write output to dblsn.log -ot dblsn.log # Remote ID file (defining the scope of $remote_id) -r SIS_CarDealer_LP_DBLSN_REM.rid # Message handlers # Watch for a notification without action -l "poll_connect=tcpip(host=localhost); poll_notifier=CarDealerNotifier; poll_key=$remote_id.no_action;" # Signal dbmlsync to launch, sync and then shutdown -l "poll_connect=tcpip(host=localhost); poll_notifier=CarDealerNotifier; poll_key=$remote_id.sync; action='run dbmlsync.exe -c filedsn=SIS_CarDealer_LP_DBLSN_REM.dsn -ot dbmlsync.log -qc -e sa=on';" # Shutdown the listener -l "poll_connect=tcpip(host=localhost); poll_notifier=CarDealerNotifier; poll_key=$remote_id.shutdown; 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.
