I don't agree. After being an instructor for oracle courses for the past
3 years, I can say very confidently that the years of experience count
for nothing when it comes down to really knowing how oracle works.
Funny. I can say exactly the opposite.
But then again, I've been a dba for a LOT longer than 3 years.
There's people that "use" oracle and there's people that use oracle. How
long you do it doesn't really mean much. Its all about how curious you
are, and how much effort you put into it.
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.
Especially nowadays, you can be a full-time full-GUI DBA using nothing
but enterprise manager (I'm not saying this is good, mind you) -- but
you see it more and more. And I honestly believe someone that works like
this for 3 or 4 years has a far less good knowledge about oracle than
someone taking it apart for 6 months, doing so passionately.
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".
