The 11g OCP certification should be available this year. You can register for the production exam 1Z0-050 New Features on Prometrics and pass the exam on Mon Feb 18th or later, the OCA exams 1Z1-051 SQL Fundamentals and 1Z1-052 Admin I are in beta and the OCP exam 1Z1-053 Admin II is planned for early 2008 (well, the OCA exams are planned for late 2007, so do not rely on this timeframe).
