Oracle Certification Program
The Oracle Certification Program is a professional certification program by Oracle Corporation. Three levels of certification are offered in several disciplines, namely: Oracle Certified Associate (OCA), Oracle Certified Professional (OCP), and Oracle Certified Master (OCM).
You may also want to invest in some Oracle Training courses to help you to prepare for the certification exams. The following certifications are available:
 Database Certifications
 Oracle Database Certified Associate (OCA)
The OCA tier was designed to provide for an entry-level DBA certification designation for the Oracle platform. Information Technology professionals with little or no Oracle experience can obtain the knowledge and skills necessary to break into the highly lucrative and challenging Oracle profession. The skills obtained from completing this certification track will allow the candidate to participate on Oracle-related projects acting as junior-level DBAs. Typically, a senior-level DBA will work closely to assign appropriate DBA tasks to strengthen existing skills, and challenge them to learn slightly more advanced procedures.
 Oracle Database Certified Professional (OCP)
This certification was designed for mid to senior-level DBAs with one or more years of focused Oracle DBA experience. The knowledge and skills obtained from completing this tier of the certification program prepare the DBA to provide the full assortment of DBA-related tasks - from Database Design and Development to production tasks such as Network configuration, Performance Tuning and Backup & Recovery.
 Oracle Database Certified Master (OCM)
There is a third tier to the Oracle DBA Certification Track, the OCM. This track is targeted at very senior level DBAs and Oracle consultants. If you have less than 5 years of serious Oracle work experience; and if you have not spent many hours working with and testing advanced Oracle features, you should not even consider this tier as an option.
 Oracle Database Certified Expert (OCE)
This is a stand-alone tier that grants credentials that recognize your expertise in specific technologies, architectures or domains not covered in the traditional hierarchy-based Certified Associate and Certified Professional certifications. These certifications are niche oriented – based upon specific products or technologies rather than broad job roles. Expert-level competencies range from foundational skills to mastery of advanced technologies.

 Oracle Database Certified Specialist (OCS)
This is a stand-alone tier that grants credentials that are typically foundation-level implementation-oriented certifications. While these certifications are available to all candidates, becoming an OCS is ideal for employees of current Oracle partners, employees of integrators seeking to become Oracle partners and individuals who plan to apply for work with Oracle-authorized partners.
