1) Brain Dumps are considered cheating by Oracle. If you are suspected of using brain dumps you can be disqualified from the OCP program. As such, posting on a forum for access to dump is not a great idea.
2) Study materials are typically available from book stores. You can see a list of the necessary books here (http://www.oracle-base.com/misc/ocp-certification.php

3) Your first stop for any question related to oracle certification should be this website. (http://education.oracle.com/pls/web_pro ... page_id=39
). it will tell you everything you need to know about each type of certification, included instructor lead training in your region.
