• Release Update (RU) patches are cumulative patches for EBS R12.2.x environments.

• They include:

  • Security fixes

  • Performance improvements

  • Stability updates

• The latest July 2025 RU can be applied on top of your existing R12.2.x environment to stay current with Oracle support requirements.

🔹 3. Oracle Java Virtual Machine (OJVM) Patches

• Oracle also released OJVM patches as part of July 2025 CPU.

🔹 4. Best Practices for Applying July 2025 Patches

1. Review Readme Documents

   • Always read the patch README for pre-requisites, compatibility, and post-install steps.

2. Use Latest AD/TXK Delta

   • Ensure that you are on the latest AD and TXK delta levels before applying RU/CPU patches.

3. Apply in Non-Production First

   • Test patches in cloned environments to validate impact on customizations, interfaces, and performance.

4. Coordinate with Business Users

   • Schedule downtime with business users as patching requires appsTier & dbTier shutdowns.

5. Run ETCC (EBS Technology Codelevel Checker)

   • Use ETCC to confirm required database and system patches before applying CPU/RU/OJVM.
