RE: Best suggestions to become an Orac1e C0re D.B.A

Quite a religious question. But still every religion can be tested by practice.
 
OK, first there are many fields to learn even for DBA. Security, performance, 
robustness(aka High Availability)
Then there is a philosophy. 
You may take a black box approach: learn what Oracle says kind of "if number X 
is high then increase this parameter"
Alternatively you may learn how rdbms work in principle. "The Red Book" 
(http://redbook.cs.berkeley.edu/) supplemented with Oracle internals knowledge 
is a good start. 
In practice you need both approaches. When there is no time then you have to 
take a black box approach: find a recipe(solution) and apply it quickly. When 
there is time or you have now ready recipe then you can deduce how things work 
and what is wrong if you know principles. If you do not then you can only 
ask(i.e. google or so)
 
Basically just like a doctor you have to know and remember a lot. Just like a 
doctor you will have to make decisions based on science or on experiment and 
experience only w/o understanding what's really going on.  This is may be one 
of the biggest differencies from a developer: developer usually has a time to 
think about design. If he/she thinks is another question but in principle it is 
so. DBA often has to react quickly. It helps to collect basic recipes "what to 
do if..." The last item could be "look for another job" or so
