Understanding Oracle Home and Install Home

When multiple Oracle products are installed on one computer, common internal and third-party components are installed to a central location called Oracle Home.

On Windows platforms, the Oracle Home (contains Oracle database products) location is defined in the system environment variable called EPM_ORACLE_HOME (contains all Oracle products) and the default location is C:/Oracle/Middleware/PMSystem11R1. Middleware contains products such as WebLogic.

On UNIX platforms, the Oracle Home value is stored in .hyperion.<hostname> in the home directory, and the default location is $HOME/Oracle/Middleware/EPMSystem11R1.

See the Oracle Enterprise Performance Management System Installation and Configuration Guide for information on changing the Oracle Home location.

Oracle Home contains a \common directory. An Oracle Hyperion Enterprise Performance Management Workspace installation adds a EPM_ORACLE_HOME/products/Foundation/workspace directory to Oracle Home, which is the default installation location or Install Home for EPM Workspace (that is, EPM_ORACLE_HOME\products\Foundation\workspace on Windows, or EPM_ORACLE_HOME/products/Foundation/Workspace on UNIX).
