It seems Oracle has changed their OCP program for EBS Dba's
At the end of 2006 we were able to participate in the beta program of EBS OCP for dba's. I completed two exams, the Oracle 11i Install Patch and Maintain Applications beta exam and the Oracle 11i System Administration beta exam.
Now Oracle has changed the OCP program and added two new exams to the list. They also deleted two exams, the Oracle 11i System Administration and Implement Oracle Workflow 11i were removed out of the OCP program and they added Applications DBA Fundamentals I and II. Also, when you are already an OCP 9i or 10g, you only have to pass the 1Z0-233 Oracle 11i Install Patch and Maintain Applications exam to become a certified EBS Dba professional.
Also, the results of the beta exams are supposed to be known in April...
