Xiaomao,

Congratulations!

I'm taking that exam (not the Beta anymore) next week, and since it's a new exam there is not too much information about it. Actually I'm focusing my study on the following:

- OTN article (top-20 new features):
http://www.oracle.com/technology/pub...k1_10gdba.html

- Notes from Tim Hall on Oracle-Base, along with the references pointed by him:
http://www.oracle-base.com/articles/10g/Articles10g.php

- Official documentation: http://tahiti.oracle.com (obviously I'm not reading EVERYTHING, only the most relevant topics IMO)

- Oracle 10g - New Features from Oracle Press

- A test environment

Since you already took the exam, can you tell what your sources were and confirm if the above are enough?

From what I've seen until now, the new features stuff seems much easier now and I believe that the Oracle approach may change on the OCP exams.
