    Assuming you want to expand your Oracle application development skills (and not your DBA skills) you could look at gaining the 1Z0-047 Oracle Database SQL Expert certification. A good study guide for this is OCA Oracle Database SQL Expert Exam Guide: Exam 1Z0-047. I used this in combination with the Oracle 11g SQL Reference to pass 1Z0-047.

    Working with Oracle in production for a couple of years will also help you to expand your Oracle skills.

    As an introduction to essential Oracle concepts and techniques have a look at Expert Oracle Database Architecture: 9i and 10g Programming Techniques and Solutions by Tom Kyte.
