Oracle DBA topics for PL/SQL developers
===

Sorry for asking a non programming question here. 

I'm a PL/SQL developer. My manager is arranging a DBA training for me. Just asked for some DBA topics I would be interseted in.

So if anybody can help me out with the DBA topics that would help a pl/sql developer or should be compulsorily known to a PL/SQL developer.

Many thanks in advance.
