and found the following
[b]Recommended Training and Preparation
The exam that will be in effect through October 31, 2006 has been validated against Oracle Database 10g and Oracle Database 10g R2 and is compatible with both. Classroom training, practice and experience on either release is suitable preparation. Starting November 1, 2006 the focus of the exam will be solely on Oracle Database 10g R2, and new topics will be introduced. The new topics are footnoted in the Exam Objectives [/b]
So it looks like I have to get new books which are written for 10gR2. Please check ....
