Amazon Relational Database Service (Amazon RDS) for Oracle now supports the Oracle April 2026 Release Update (RU) for Oracle Database versions 19c and 21c, and the corresponding Supplemental Patch Bundle for Oracle Database version 19c. We recommend upgrading to the April 2026 RU as it includes security updates for Oracle database products.
Starting with April 2026 releases, the Oracle Spatial Patch Bundle has been renamed to Supplemental Patch Bundle (SPB). The SPB includes additional database patches recommended by Oracle for specific use cases, such as Oracle Spatial, Oracle Data Pump, and Oracle GoldenGate.
You can apply the April 2026 RU from the Amazon RDS Management Console, or by using the AWS SDK or CLI. To automatically apply updates to your database instance during your maintenance window, enable Automatic Minor Version Upgrade. You can apply the Supplemental Patch Bundle update for new database instances, or upgrade existing instances to engine version ‘19.0.0.0.ru-2026-04.spb-1.r1’ by selecting the “Supplemental Patch Bundle Engine Versions” checkbox in the AWS Console.
You can also use AWS Organizations upgrade rollout policy to stagger automatic minor version upgrades for your Amazon RDS database instances. This feature allows you to automatically apply updates to non-production environments, validate the updates, and then automatically apply the same update to production environments. For additional details about using AWS Organizations upgrade rollout policy for automatic minor version upgrades, refer to Amazon RDS for Oracle documentation .
