OCA & OCP Certification Books

OCA & OCP Exam Books
Sybex OCP Oracle 10g Admin I/II	Nice easy reading and good books to get you through the exams
Osbourne OCP Certification all-in-one exam guide	I always like two books on the same subject, so this book compliments the one above.
Advanced Oracle Books
Oracle Database 11g PL/SQL Programming - Michael McLaughlin	This book is more on the development side, it includes lots of the new 11g features and is one of the best books i have read, it explains things clearly without to much waffle (straight to the point).
Apress Expert Oracle Database 10G Administration - Sam.R.Alapati	This book is from the view of a Oracle DBA admin, although a heavy going book, I highly recommend it.
Apress Expert Oracle Database Architecture 9i and 10g programming techniques and solutions - Thomas Kyte	This book is more from the developer side and compliments the above book, this book is the next version of the excellent 'Expert one-to-one' series.
Osbourne Oracle 10g The Complete Reference - Kevin Loney	For a Oracle junior DBA this book is a good book to have on your desktop
Osbourne Oracle database 10g performance tuning Tips and Techniques - Richard Niemiec	This is an excellent book for tuning the database, has a excellent chapter on the mysterious x$ tables (advanced Oracle stuff).
