Amazon RDS for Oracle now supports July 2026 Release Update

Amazon RDS for Oracle July 2026 Release Update

Amazon RDS for Oracle now supports the July 2026 Release Update (RU) for Oracle Database versions 19c, 21c, and 26ai. We recommend upgrading to the July 2026 RU as it includes security updates for Oracle database products.

Naming Format Change

Starting with July 2026 releases, the naming format for an RU in Oracle Database 19c changes to .ru-.mrp-.r. For example, the RDS for Oracle July 2026 quarterly RU for Oracle Database 19c is named 19.0.0.0.ru-2026-07.mrp-2026-07.r1. Oracle Database 21c RUs retain their existing naming format.

Monthly Critical Security Patch Update (CSPU)

For Oracle Database 19c and 26ai, Amazon RDS will make the monthly CSPU available as an MRP version that bundles the CSPU with additional Oracle-recommended fixes.

What to do

• Apply the July 2026 RU from the Amazon RDS Management Console, or by using the AWS SDK or CLI.
• Enable Automatic Minor Version Upgrade to automatically apply updates during your maintenance window.
• Use AWS Organizations upgrade rollout policy to stagger automatic minor version upgrades for your Amazon RDS database instances.
