About Middleware Home and EPM Oracle Home

Middleware Home

A Middleware home consists of the Oracle WebLogic Server home, and, optionally, one or more Oracle homes, including EPM Oracle home. A Middleware home can reside on a local file system or on a remote shared disk that is accessible through Network File System (NFS).

The Middleware home location is defined during the first product installation on the computer. Subsequent installations on the computer use the previously defined location. The default installation directory is Oracle/Middleware. The Middleware home location is referred to as MIDDLEWARE_HOME throughout this document.

EPM Oracle Home

An Oracle home contains installed files necessary to host a specific product, and resides within the directory structure of the Middleware home. The EPM Oracle home contains files for EPM System products.

Components of EPM System products are installed in the EPM Oracle home directory under the Middleware home. The default EPM Oracle home location is MIDDLEWARE_HOME/EPMSystem11R1. In addition, common internal components used by the products are installed in EPM Oracle home. Choose the location carefully to ensure that the location has enough disk space for all products that you are installing on the machine. You cannot change the location.

The EPM Oracle home location is defined in the system environment variable called EPM_ORACLE_HOME. The EPM Oracle home location is referred to as EPM_ORACLE_HOME throughout this document.
