Honestly, if you need a third-party to explain your scheme with a 6000-word, 20 page document there might be some sort of issues with your scheme.
I tried using nothing but the Oracle website to determine what the terms of usage are, and what the cost would be. It's confusing, buried many levels deep, in multiple documents in different places.
They use the term "processors" to refer to how 11 is licensed. They give you a per-processor price. Then in a footnote they say that you have to multiply the number of cores you use by a ratio that is different for different platforms and/or CPU models in order to determine your "processor" count.
Where is this ratio? In a different document that they don't bother to link to. Seriously. Well, there IS a link, but it takes you to the index page of massive document library. Browsing around there in obvious places got me nowhere. I finally googled for it with "site:oracle.com" and found it, but I still have no idea where on their website they put it.
And then extorting money from your company via the threat of lawsuits if, speaking purely hypothetically, your company is determined - because of said processor-vs-cores distinction - to be out-of-bounds on the number of installed databases during an audit.
Oracle has all of the ethics and humanity of a lawnmower.
Last time I told the salesperson: "I will not bring any more Oracle products into my company for the simple reason that Larry Ellison is an asshole who is hostile to his customers." The response? "Yeah, I get that a lot."
Honestly, I felt sorry for the guy.
