Initializing help system before first use

# Environment Configuration

Integration with the Compute Interface must be explicitly enabled, and the URL identifying the location of your Xpress Insight Server must be set before Xpress will create and send jobs. You can also enable additional configuration by settings the path to a configuration file.

## Configure System Environment Variables

Several environmental variables need to be configured prior to the Xpress software being started. You can set them in the Command Prompt window before starting the Optimizer console or add them using the Windows Control Panel if you want to set them globally.

## Set Environment Variables using the Command Prompt window

1. Open a Command Prompt window, and enter:

        SET XPRESS_COMPUTE=ON

   to turn on compute integration.
2. Enter

       SET XPRESS_COMPUTE_URL=http://<INSIGHT5_SERVER_NAME>:8080/

   to set the hostname and port number of your Xpress Insight Server.
   Note: If you are connecting to the Xpress Insight Server using an HTTPS URL, Xpress will need to read SSL certificates from the `mmssl` configuration directory. This directory must be initialized by executing the following at the command-line:

       mmssl setup

## Set Environment Variables using Control Panel

1. From the desktop, click on the Start menu icon and then type `environment variables`.
2. Click Edit the system environment variables.
3. In the Environment Variables window, below the System Variables pane, click New.
4. In the New System Variable window, enter the Variable name and Variable value pairs shown below:

   Variable name | Variable value
   XPRESS_COMPUTE | ON
   XPRESS_COMPUTE_URL | http://<INSIGHT5_SERVER_NAME>:8080/

5. Click OK to close each of the three open dialog windows.

## System Library Requirement for Linux

Compute integration cannot be used in the Red Hat Enterprise Linux (RHEL) 6 compatible version of Xpress.
