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.
If you have already paid your Oracle Database Extended Support fees, you may be eligible to receive a credit that Oracle will apply against your Oracle account.
Oracle E-Business Suite General Manager Cliff Godwin officially shared the info during his presentation at OAUG COLLABORATE19 event in San Antonio,TX.
