Server Configuration Options
Depending on a variety of variables, such as your server operating system, your hardware resources, and your site's performance requirements, you can configure your environment to support physically separate or logically separate servers. In some cases, the PeopleSoft standard installation procedure recommends one or the other depending on, for example, the combination of your database type and operating system. Any platform-dependent configuration requirements are discussed in the product installation documentation.
See PeopleSoft 9.2 Application Installation for your database platform.
