ORACLE APPS : APPS DBA vs ORACLE DBA

What the difference between an Oracle APPS dba and a regular Oracle dba?

From my point of view an APPS dba is an Oracle dba +. That means as an APPS dba , I believe you are an Oracle dba, but with additional tasks.

From OTN applications forum I found the following, which I believe is a correct summary of what an APPS dba should be capable of performing

1)Oracle DBA
2)Oracle Applications Concepts (Manual Available in oracle.com)
3)Concurrent Processing Architecture ( Use www.dbatoolbox.com or medallions if you have one)
4)Web and Forms Server Architecture (9iAS Doc's)
5)Using AD utilities and AD procedures (Manual available)
6)Installing and Upgrading Applications (manual available )
7)Cloning Oracle Applications(White paper)
