Oracle's Lifetime Support policy has three phases: Premier Support, Extended Support, and Sustaining Support. For details about coverage during each phase, see:
You can purchase a support plan for your licensed products to obtain Premier Support. There is an additional fee for Extended Support.
Due to the certification timing of Oracle E-Business Suite with Oracle Database versions beyond 12.1, Oracle has waived Extended Support fees for Oracle Database 12.1 and 11.2 for Oracle Database licenses used for Oracle E-Business Suite through December 2020.
