I know. Oracle's marketing is doing Oracle no service by mischaracterizing RAC ... and for that matter GRID. They are creating misunderstandings that only hurt the product's acceptance and the very sales they think they are enhancing.

That depends on more things than just the software developer's name. And it depends on why RAC is being purchased because there are three entirely different reasons for buying it.

  1. High availability
  2. Scalability
  3. Failover

The criteria of what will and will not benefit are different.

Once again ... it depends on why you are buying it. Some applications are, as Tom Kyte has called them, RAC killers. They are just not going to ever run on RAC and probably on any similar technology. But for many others it can be a wonderful way to implement tremendous cost savings by building out rather than up.
