If you Title Oracle Developer (Pl/Sql) please check step exam:
Oracle Database SQL Expert | 1Z0-047
Oracle Database 11g: SQL Fundamentals I | 1Z0-051
Oracle Database 11g Release 2: SQL Tuning | 1Z0-117
Oracle Database 11g: Program with PL/SQL | 1Z0-144
Oracle Database 11g: Advanced PL/SQL | 1Z0-146
Program with PL/SQL | 1Z0-147
Based on your statement 'I have 6 years epx in SQL/PL SQL.' -- my first inclination would be to suggest 1Z0-144: Oracle Database 11g: Program with PL/SQL. It is the standard exam for PL/SQL developers to start with and passing this (in conjunction with your 1Z0-007 score) will earn you the Oracle PL/SQL Developer Certified Associate credential. 1Z0-047 is an older version of the PL/SQL exam. I generally recommend 1Z0-144 over 1Z0-147:
If you pass 1Z0-144, you might then consider pursuing 1Z0-146: Oracle Database 11g: Advanced PL/SQL. Passing this exam after earning the OCA will make you an Oracle Advanced PL/SQL Developer Certified Professional.

You are welcome!
Thankyou,Please tell me which Book or Materials need to be considered for the preparation of 1Z0-144?
