In this section, we explain how to install and run the OCALA Proxy in Windows, using the OCALA_Setup.exe file. The OCALA proxy was compiled in Visual Studio.NET 2003 on Windows XP Professional.

Installing OCALA

To install the OCALA proxy, double click on the OCALA_setup.exe. The setup program should be run in administrator mode. The setup program will launch the graphical configuration wizard at exit. It will also start the OCALA proxy as a windows service. You can control (Start/Stop/Configure) OCALA at any time by right clicking on the OCALA icon in the Windows System tray.

Configuring OCALA

The setup program launches the configuration GUI at exit. If you want configure OCALA at a later time, choose the Configure OCALA menu item from the OCALA group in the START menu. A configuration GUI pops up. In the most common scenario, you will only need to set the name of your machine. You may need to restart the OCALA proxy for some configuration changes to take effect.

If you do not have java 1.4.2 or higher installed, you will not see the configuration GUI. Please refer the section on "Manually Configuring OCALA" for instructions on how you can manually configure OCALA. The configuration GUI has been only tested to work with Sun Java.

STEP 3: Running OCALA

  • If you are running OCALA as a service, you can start the OCALA proxy using the popup menu associated with the OCALA Proxy Monitor icon in the System Tray. OCALA may take a few minutes to start up and initialize the various overlays. You can check the status of OCALA by hovering the mouse pointer over the OCALA Proxy Monitor icon.

  • If you are running OCALA as a standalone program, you can just choose the Run OCALA menu item from the OCALA group in the START menu.


OCALA_proxy needs to access the Interent. If your firewalls warns you about this, please configure your firewall to allow OCALA_proxy.exe to access the Internet.


The configuration files used by OCALA are in the config_files subdirectory located in the same directory as OCALA_proxy.exe. The Java configuration GUI mentioned in the previous step modifies these files.
