Here is a quick guide outlining the steps I used to download the Oracle EPM files for an Essbase version 184.108.40.206 installation.
1) Go to Oracle eDelivery (http://edelivery.oracle.com). Provide login information. From the "Media Pack Search" window, select the product pack “Oracle Enterprise Performance Management System” and Platform (ie Windows).
I hope this provides a clear explanation of where to locate the EPM files for Essbase version 220.127.116.11. As Oracle issues updates and new releases, the file names may change but the basic process should remain the same. My next post will provide more details on how to complete the installation.
