This is an example of the posts which convinced me that dispensing advice
for newbies is not a smart thing to do. The advice for newbies in any
kind of profession was given a long time ago. It reads "ora et labora".
One needs to work and read and then work some more. The "ora" part is not
as necessary as the "labora" part. If I ever gave an advice to a newbie and
he came back with a question like this one, I'd have to cover my face with burka
because I'd feel so ashamed that I would never want to show my face again. I
strongly advise against "introducing Oracle to newbies". If you have a competent
engineer, train him, if you have an incompetent, fire him. Good computer engineer
must be capable of reading documentation. Messing things up and then asking not so
bright questions is a sign of a hopeless soul who would be better off by driving a
taxi or giving opinions on te Fox News Network then working with Oracle RDBMS. If
any trainee of mine ever asked a question like this,
Lately, Oracle Corp. is stressing ease of use and its new mantra is the one about the
obsolescence not only of a DBA but any qualified technical professional. The message reads
like this: "It's easy, you don't have to know anything, just buy the stuff and everything
will work". Unfortunately, artificial intelligence still cannot replace the one produced by
the mother nature. Computers in a professional environments are not to be managed by amateurs
or chaos will ensue. Unfortunately, Oracle Corp. has contributed to such situation as it has
been dispensing OCP certificates to guys asking questions like this. Therefore, the best advice
I can dispense is still "close your eyes and think of England".
