I'm a "kind of" DBA, but not the real deal (yet). I do things from the application perspective which all you real DBAs laugh at (stop it).
I like competition, it's good for the soul. I've begun wondering who the best DBA in the world would be. As far as I know, there is no such competition.
A good place to start though would be the Oracle Certified Masters. Based on the curriculum to achieve said credential, I'd say these people would rank among the best right?
What about those that choose not to take it, but are more than worthy? Would it be those that blog? How could I ever know? (No Howard, it doesn't really matter, it's just curiousity).
Anyway, my DBA got mentioned by one of the better known DBAs out there, Tanel Poder. I'd say that's pretty cool.
Miladin Modrakovic is his name, Oraclue is his game. (Corny, I know).
Joking aside, I like (love?) working with this guy. If there is something I don't understand I can pass it along without fear of him not knowing. That hasn't always been my experience. My first "DBA" gig I was the only one there...I knew everything, or had to. It's such a relief to know that I don't have to know everything.
So if you like that real DBA stuff, internals, diagnostics, etc., check out his site. It's well worth the read.
