Funny. I can say exactly the opposite.
But then again, I've been a dba for a LOT longer than 3 years.

That, I agree.
Having said that, I'll also mention that anyone who has been a dba for 10 or more years PROBABLY has a little bit more commitment to the job and the type of work than a newb freshly painted with a "certification"?

Might be just me, but someone who shows a track record in a given profession is at the very least showing a willingness to stick to the job and learn about it.

Of course: some might classify a long time dba as someone who has become stale?   I've got news for those: it *is* a stale job. How many different "innovative" ways can one manage space allocation?

Yeah sure: nowadays you might look at a nice flash graphic - that essentially shows you nothing above the basic numbers. A dba trained in more traditional fashion might actually have looked at said numbers and tried to make some sense of them over time. Like: detect trends, capacity plan, find abnormal patterns of growth, etc. Something you simply cannot do looking at graphics.

Don't expect anyone with little experience to do it anytime soon, though.

And there is a LOT more about the dba job than simply "taking Oracle apart".
