The DBA 3.0 Upgrade
In 2008, Harald van Breederode and Joel Goodman wrote a white paper titled "Performing an Oracle DBA 1.0 to Oracle DBA 2.0 Upgrade" in which they suggested DBAs needed to add storage and OS skills to remain relevant in a shifting technical landscape. The role of today's DBA has broadened considerably and with that comes a new set of abilities and concepts to be learned and mastered. DBA 2.0 was written prior to the release of Oracle 11g and 12c, so the Oracle DBA 3.0 upgrade adds Cloud and virtualization to the DBAs repertoire. Their inclusion also demands that DBAs be able to better manage security and compliance challenges that come with hybrid and Cloud environments, the ability to adapt to continuous deployment cycles, and heterogenous and comingled data stores. Most significantly DBA 3.0 signals an emergence of the DBA from a mostly utilitarian and anonymous role to one that is more in the limelight. The growing emphasis and influence of data and data-driven decision making means that the DBA must be a partner and driving force in the business and not simply a custodian of the data. Learn what it will take to build or upgrade your skill set to Oracle DBA 3.0, and how to encourage and mentor a new generation of data professionals into the field.
