On what days during the month does Oracle apply patch updates to fix bugs, apply code optimizations, and add new features?

• A. the third Friday of each month to apply to both TEST and PROD simultaneously
• B. the first and third Friday of each month; first Friday for TEST and third Friday for PROD
• C. the second and fourth Friday of each month; second Friday for Test and fourth Friday for PROD
• D. the first and second Friday of each month; first Friday for TEST and second Friday for PROD

Answer: (B)

The patches follow a two-step monthly cadence: the testing environment is updated on the first Friday of the month, and the production environment is updated on the third Friday. This separation gives customers a window to test bug fixes, code optimizations, and new features in TEST before they go live in PROD, minimizing risk to production operations. Updates are typically applied during off-peak hours to reduce impact.

The other options don’t fit because they either apply patches to TEST and PROD on the same Friday, or use different Fridays (second, fourth, or a combination of first and second) that do not align with the established testing-before-production release process.
