The WAN Optimizer

You can significantly improve Enterprise Architect's performance in a Wide Area Network (WAN) by reducing the amount of data transmitted and, in turn, the number of network calls made. To achieve this, you can use the Sparx Systems Wide Area Network (WAN) Optimizer, a lightweight server installed on a Local Area Network (LAN) connection to a Database Management System (DBMS) that hosts an Enterprise Architect repository. You can configure the server to listen for client connections on a particular port; it acts as a local proxy to execute queries and return the results in a compressed format to the client.

In this diagram, transmission between Enterprise Architect and a DBMS is depicted first without and then with the WAN Optimizer.

You can download the WAN Optimizer installer from the 'Downloads' page of the Registered Users section of the Sparx Systems website. The Wan Optimizer Service installer package provides two installable features for the target machine:

  • WAN Optimizer Service - the installer also helps register and start the service on the target machine, and add it to the Windows Startup folder
  • WAN Optimizer Admin Client - to enable an administrator to administer and configure the service from a remote client

The Optimizer has its own Sparx Systems WAN Optimizer User Guide. See that Guide for more information on:

  • WAN Optimizer Components
  • Installing and Starting the WAN Optimizer Service
  • Configuring the Service
  • Troubleshooting

The WAN Optimizer forms the basis of the Sparx Systems Cloud Services, which in turn is the core of the separately-purchased Pro Cloud Server. If you are using the Clod products, you have no need to use the WAN Optimizer.

The WAN optimizer forms the basis for the Sparx Systems Cloud Services, which in turn is the core of the Sparx Systems Pro Cloud Server. Both of these facilities provide the basic function of the WAN Optimizer, but do so faster and more securely; they also have many more additional features.

Whilst you can still use the WAN Optimizer as described here, we recommend that you review the Cloud Services products and use one of them instead.
