Oracle provides a limited-use license of WebLogic Server for use with EPM System products. Typically, EPM System Installer installs WebLogic Server for you.
However, if you have an existing WebLogic Server installation and want to use it instead of the WebLogic Server installed by EPM System Installer, note the Middleware home location for the WebLogic Server installation. During installation, you must install EPM System products to this same Middleware home. If EPM System Installer detects an existing WebLogic Server installation in the installation location, it does not install WebLogic Server.
For additional information about using WebLogic Server in a distributed environment, see “Installing EPM System Products in a Distributed Environment” in the Oracle Hyperion Enterprise Performance Management System Installation and Configuration Guide.
