I have few years of experience with Oracle 7.x and 8. Now I want to take the DBA certifiaction exam, but I don't have a clue as to how to prepare for the exam. Could you please help me with this. I tried to find out the info from posts from other users, but I don't understand so many things like for eg. 'STS'. Could someone please give me an idea about preparation for the exam. I will appreciate ur help.

Thanks in advance
