Set Up Exadata for Cloud Control 12.1.0.2

I recently helped setup an Exadata X2-8 Database Machine with the latest version of OEM Cloud Countrol (12.1.0.2). A few documents do exist for this process. However I found a few inconsistencies and problems; I think the existing documents I found were written on older versions of OEM and older versions of the tools. I’m publishing my final procedure here with hopes that it helps you, but as always please cross-reference this with the appropriate documentation before doing anything in your own environment.
