    This is a discussion about database performance. Certain things are so obvious as to need not to be explicitly restated.

    How would your management measure the peformance of the servers and applications you're responsible for?

    The fact that RAC scales well, or scales better than a big NUMA box is NOT obvious. The cluster software has to prove itself first. Mangement of the cluster itself can overwhelm the associated hardware. Any poorly written SQL query is a good example of this sort of problem.
