Install a development environment. Web Server Setup: If you did not configure your web server automatically during the installation process, you will need to connect it manually. If your web server is using a port number other than 80, you will need to change the CPF WebServerPort and WebServerURLPrefix parameters to your web server’s port number in order to connect with your IDE. In order for your web server to implement any configuration changes, you should restart your web server after the installation finishes. Advanced Setup: If you will be performing memory intensive activities, allocate system memory accordingly. Review details on how InterSystems IRIS interacts with third-party software.
