Oracle’s 9i OCP (Oracle Certified Professional) DBA (Database Administrator) certification is a mid-level certification for IT professionals who manage large-scale databases or develop applications that are used enterprise-wide. The Oracle 9i OCP was introduced in late 2001 and will likely stay very popular until the arrival of the Oracle 10G certification. There is no specific prerequisite for this certification; however, by starting your Oracle certification journey on the 9i path, you will achieve the OCA (Oracle Certified Associate) certification along the way.
