RE: Oracle RAC cost justification?

Thanks, Tom M. had sent those to me privately also. Those papers were exactly what I was looking for... I was trying to go beyond the hype of RAC and see how people justify the costs of RAC -- apparently there're opinions on both sides on this topic...

Thanks for sharing...=20

Thanks!=20

RAC and a cost effective solution is an oxymoron. Add another node...

If you have'nt seen these papers, they sum it up nicely and accuratly in my opinion:
