Clean uninstall of EPM V11.1.2.4

1.  Begin with uninstall

 All Hyperion folks know it clearly that dealing with Hyperion setup will require knowledge about uninstalling Hyperion suite completely.
As it is pending from a long time after we started with Hyperion v11.1.2.4, here are basic steps to follow to uninstall Hyperion EPM V11.1.2.4


Uninstall using same admin credentials with which we have installed Hyperion EPM V11.1.2.4

2.  Uninstall related software

EPM uninstaller uninstalls JRE which comes with EPM installer. It is used for installation and configuration of any Hyperion products. The same JRE is used to uninstall related non-Hyperion software components like weblogic, OHS. So, if we proceed for EPM V11.1.2.4 uninstall, we cannot uninstall related software components by proper procedure and so we might end up in option of deleting folders and cleaning related stuff.

Thus, it is very important to follow following steps before uninstalling EPM V11.1.2.4.

Uninstall Weblogic

Run WL Uninstaller separately





Uninstall OHS


Run OHS Uninstaller separately






Uninstall Oracle Application Developer

Run Oracle Application Developer uninstaller separately

 Once we uninstall above products, check if the respective directory is removed from MIDDLEWARE_HOME.

3.  Uninstall Oracle EPM V11.1.2.4

Uninstall EPM System V11.1.2.4
Stop all Hyperion and Oracle services

Uninstall Hyperion EPM system by running "uninstall.bat" located at "MIDDLEWARE_HOME\EPMSystem11R1\uninstall"





Once the uninstall is complete, the directory "MIDDLEWARE_HOME\EPMSystem11R1" should be removed.

4.  Post uninstallation tasks

Check from Start--> All Programs, all related shortcuts should have been removed.

Windows Registry

    Delete or rename installer records in C:\Program Files\common files\InstallShield\* if no other programs installed by this tool remain.
    Check for Oracle EPM related entries in the inventory.xml file located in C:\Program Files\Oracle\Inventory\ContentsXML and remove these entries from the file.

    Clean up any remaining Hyperion-related files and directories under the user's install home. E.g. "D:\Oracle\Middleware"
