Every Oracle DBA dreams to get this message from Oracle and one day become an Oracle Certified Master. But when it comes to the preparation, it seems to be hard as there s no book available in the market for OCM 19c exam.

This Study Guide contains the following information:

• In the beginning of each topic, a reference from Oracle documentation and metalink notes is provided to get more information on a specific subject.
• Each topic is explained in a practical examples using both graphic user and command line interfaces.
