Updated: 19th October 2015
Extended Support for Database Release 11.2 is now available through December 2020.
Oracle Database 11gR2 (11.2) has entered the Extended Support phase as of 1st February 2015. This would normally mean that an additional Extended Support contract would be required in order to continue to receive bug fixes and proactive security patches. However the Extended Support fee has been waived from February 2015 to end of May 2017 for all customers. Customers do not need to do anything to take advantage of this waiver. Bug fixing and patching will continue as per normal during this period.
For further information please review
As a general recommendation when moving to DB12c, customers should upgrade to the Multitenant architecture as non-CDB architecture is deprecated in Oracle Database 12c, and may be desupported and unavailable in a later Oracle Database release.
