Think of RAC as "OPS v2", or probably more precisely,
"Cache Fusion v2".  Older versions of OPS used to
require carefully partitioning of a anticipated
application across the nodes. In 8.1, this was
lessened to some extent and even more so in 9.  Thus
in 9i, the claim is that you can run a standard
application under this "new" OPS without needing to
worry about the partitioning issues.  Thus you can run
a (R)eal (A)pplication" under the (C)luster
