Oracle released the first version of its 11g database in 2007, and then the software giant began to offer Oracle 11gR2 in 2009. Still, many users have not upgraded from Oracle Database 10g, as they don’t have the time or resources to do so, especially in a down economy. According to’s Challenges and Priorities Survey 2010, Oracle 10g tops the list of Oracle database platforms -- with 85% using the database -- despite the fact that 11g has been out for three years. 

Oracle 11g and 11gR2 offer a variety of new features. In Oracle 11g, one of the most notable of these features is the Real Application Testing capability, which can dramatically shorten the time of an upgrade.  Other Oracle 11g features include automatic SQL and memory tuning and Database Replay and SQL Replay capabilities.  Included in the new features of Oracle 11gR2 is a new version of Oracle RAC called RAC One Node, which allows IT shops to RAC-enable a database on a single machine that is inside a grid. Also, read this list of top Oracle 11g features from an Oracle executive.
