2 more cents...
Like Mark Bobak right said, i think the ideal way to be a DBA is to work
through the ranks as a Developer and then become a DBA over time. this is
the best way for someone to learn the fundamentals really well and then
perform exceedingly well as a DBA.
at the same time, you really need to know your OS very well (as someone
mentioned). you just cannot be an effective DBA without being half a 'UNIX
System Administrator' yourself. you don't need to kick your friendly
sysadmin in his stomach but there is no doubt that you have to be very adept
with the OS. Sorry, there are no Windoze administrators according to me :)
when you starting becoming a specialist DBA, then certain skills really
matter. for ex, Performance DBAs. if you are good at application
development, design and programming languages such as 'C' , 'C++' or PL/SQL
then you know the kind of mistake programmers are bound to make and you can
correct them.
as many DBAs might have found out by know, a good chunk of your problems
come from the code and not always those elixir like init.ora / spfile
parameters or some config stuff at OS or SAN.
Without being a programmer you cannot possibly understand array fetching,
cursor handling, etc, very easily. somebody with that knowledge can
diagnose, troubleshoot and solve these problems quickly when compared to a
DBA who doesn't have the experience of using these programming techniques.
at the same time, certain types of DBAs (Production Support, Backup and
Recovery) need not come from a development background simply because the
work they do doesn't need those skills all the time.
yes, today's DBAs need a lot of specialised skills but a good, seasoned DBA
generally comes from a very humble background.

Gurus,
We all hearabout Oracle books and manuals that we should read. What about
non Oracle things we need to know to be a DBA? For eg couple of days ago
David Litchfield posted a link to an Oracle paper on log buffer internals.
The paper had lots of C code in it. Do I have to learn C to become a good
DBA? What is the best place to start?
Orlando.
