January 18th marks the 6th anniversary of the Oracle Critical Patch Update (CPU) in its current form as a quarterly patch. In the past 6 years, CPUs have brought a steady stream of security patches to the Oracle Database. Starting in 2010, Oracle has significantly decreased the number of patches in the database with only 32 fixes reported. The trend continues in the first release of 2011 with only 6 database fixes out of 66 total fixes. The bulk of the other 60 fixes are in Oracle Fusion Middleware, PeopleSoft and Solaris.
