Totally incorrect. You would of course have at least two NICs on a production RAC. But it's not a requirement.

Read again, I think. James' paper uses raw partitions. You can't install Oracle onto raw partitions. Therefore, he had two Oracle installs (one on the genuine PC, and one on the virtual PC). There is no requirement, even with a cluster file system, to have a shared Oracle install, and in fact I find things a great deal more workable, predictable and stable when Oracle *isn't* installed onto the shared device.

Lord. Who said it was realistic?? James doesn't even make that claim himself. It was a testbed environment in which to test specific things. It means all of us can learn RAC, despite pathetic single PC home setups. Give him some credit!!
