Oracle tends to be pretty opaque in their pricing, and part of that is because with any sale this big, there's always going to be a lot of negotiation.
Sure, it's going to be expensive, but only schmucks pay full price for a 64-core license.
Still, it's good to see the best open source database out there delivering cutting edge performance. Great work!
Yes you can get a big discount. Then when your business booms, and you need to expand, upgrade or (for some licenses) renew, Oracle gets decide how much of your profit to take off the table in licensing fees, up to the full list.
But of course I'm speaking out of school here. I have no proof Larry Ellison or his minions will pursue such ruthless business tactics. Just a feeling :)
