The expertise of Oracle database administrators (DBAs) is integral to the success of today’s increasingly complex system environments. The best DBAs operate primarily behind the scenes. They are on watch for ways to fine-tune day-to-day performance and to prevent unscheduled crises, such as a crashed database or hours of expensive downtime. This critical work requires a broad understanding of the architecture and processes of the Oracle database, as well as plenty of hands-on experience solving problems.
