T5220 = ($46K * 1 * .5) * (1.22) = $28K for Oracle license

If your application is only going to consume 15% of the total platform capacity, then run the Oracle database in a Capped Zone using 1 CPU at 100% utilization. (Unlike other operating systems, Solaris is very capable of running at 100% utilization without application failure.)
Your application has another 7 cores to play with! If you application can not leverage the capacity, then consolidate some more servers onto the platform and save some more money!

Obviously, talking to the IBM rep would know more than an Anonymous person posting dubious information. He could have saved such a customer an order of magnitude by suggesting a Capped Solaris 10 Container and allowed them to spend $28K instead of $224K!!!
The free CPU capped hard partitioning, included in Solaris 10, gives Solaris customers many more options than the common reader may be aware of.
Someone suggests paying for CPU capacity that they are not using, like the situation you posted, they you should kick them out the door... find someone who: went to University, knows how to read [the Oracle licensing guidelines] and understands basic operating system features.
Oracle will use lots of CPU threads, depending on how you tune it. We have applications which easily spread to utilize 24 threads with little tuning, but for the cost reduction, it is sometimes advantageous to reduce your footprint, so instead of using 64 threads, you leverage only 8, and run at a higher utilization. This is a fine example.
