I'd like to step back and suggest some consideration with respect to two things you wrote. The first is the word "push" and the second is the question of "need."

Anyone that lets any salesperson into their office knows the nature of the relationship. So is the word "push" really appropriate? Are CTOs and DBAs that incapable of evaluating the "need" for 7x24?

I see a lot here in this group about the added complexities, etc., of RAC but that is not mirrored in my phone ringing with requests for support. Does that mean that we're that good or that our customers are that lucky? I doubt either. I think RAC is a solid technology when implemented on the right hardware in the right way.

I'm not saying it isn't more complex but from my experience well trained people have stable environments.

You might well be correct but I can only speak from my experience here where I am located.

Speaking of which when one local aerospace firm decided to implement the Oracle grid they requested a quote to train 300 DBAs. And that is not the entire team.

A lot of fathers will appreciate that advise.
