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.
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.
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.
Cheers
