You must install your application server before you install the ATG platform. See your application server documentation for installation information.
Before you run the ATG setup program, make sure you have a supported JRE in place on your system, and that the JVM is in your system PATH. (Note: The stand-alone ATG Control Center includes its own JRE.)
You should enable GZIP compression for static files. See your application server documentation for information.
For a detailed list of system requirements for the ATG platform, see the Supported Environments page on the ATG web site (http://www.atg.com/en/products/requirements/).
