How will the twentysomething know when OEM is misdirecting him? From the help window that tells him to target a hit ratio? From the tablespace map that shows fragmentation in LMT's? Do such tools ever tell anyone to make a parameter smaller?

I think a big limitation of all GUI's I've seen has been there is no documentation of their limits or how to know when to think rather than print pretty pictures. They necessarily have an abstraction layer which can generate their own myths and superstitions.

They have their place. They _can_ be good for visualizing things that are too abstract as a columnar report. They are often good for quickly changing something, or propagating somet things. But when they claim expertise, that is far, far over the line. Claiming the ability to fully control things is pushing it, too.

On the other hand, Oracle taking over functions of a crappy OS can be a good thing.
