37.3 Changing the DVA IP Address or Port Number

The DVA communicates with the other programs (the WebAccess Application, the POA, and the DVA console) by way of HTTP. By default, the DVA uses the first IP address it finds on the server and listens on port 8301.

  1. Open the startup.dva file in a text editor.

  2. Change the IP address:

    1. Search to find the following switch:

      /ip

    2. Remove the semicolon (;) to activate the setting.

    3. Specify the IP address that you want the DVA to use.

  3. Change the port number:

    1. Search to find the following switch:

      /httpport

    2. Remove the semicolon (;) to activate the setting.

    3. Specify the port number that you want the DVA to use.

      Worker threads are assigned port numbers ascending above the main port number. For example, if you decide to use a main port number of 8500, the 5 default worker threads would be assigned ports 8501 through 8505. You must ensure that none of these incremental port numbers are already in use on the server, up to the largest possible number of DVA threads that could be started. For more information, see Section 39.1, Controlling Thread Usage.

  4. Save the startup.dva file.

  5. Skip to Section 37.6, Putting DVA Configuration Changes into Effect.
