There is this parameter, CPU_COUNT that you *can* set. Although Oracle
doesn't recommend it be changed - does anyone have any practical experience
with it ?

   Your question is one of laws and licenses, not technology.

   Only with "hardware partitioning", a feature that generally appears in
only very high-end (and high-price) servers, are you able to (legally)
license fewer CPUs than are physically installed in the server.  If your
server happens to be an IBM P520, for example, you can do what you
describe.  With most linux hardware, you cannot (yet).

   Note: you need to thoroughly understand the difference between
"hardware partitioning" and "software partitioning" as Oracle defines it.
The dividing line is quite hazy in places.
