You might be able to. You really want to visit www.oaktable.net, click the Files link, and check out James Morle's paper there called 'Unbreakable'. It contains, at its end, some deep, dark instructions on making a RAC work on a laptop -which must mean he got both instances to see the same raw partition, and that raw partition was physically installed within one machine.
>If yes, how many NICs are needed in both machines?
You only ever *need* one NIC in each machine, regardless of whether you are RAcing on Linux, Windows, or planet Pluto. However, commonsense dictates at least two, because you have obviously implemented RAC for the sake of redundancy, and having only one is a potential single point of failure.
Typically, one is used to handle 'public' networking messages (ie, client connects etc), whilst one is used to handle inter-instance communications only.
I've even heard of three being used per box: one for the public traffic, and two for the inter-instance stuff (one of these being a redundant failover device just in case).
