Well, it depends. RAC could be very cost effective using Oracle 10G on
Linux, but not everyone wants to move to 10G yet. Using 9i and AIX,
RAC would be more costly because you still need to pay for HACMP as a
cluster software and you need to pay 50% for RAC Option. Because of
Oracle prices, the higher cost of HW (that can't be utilised on 100%
because of active-passive HACMP setup) is usually less important than
the Oracle related costs.
