What are Untested Patches?
Oracle Service Cloud, Product Updates
Untested patches are deployed to individual customer sites when Oracle determines a need to update Oracle Service Cloud in a timely manner outside of the scope and schedule of Maintenance Packs. For more information about updates please see Answer ID 2525: Oracle Service Cloud - Product Release Updates
Untested Patch Contents
Each update includes a small set of code changes to facilitate the resolution of one or more defects a customer has reported to Technical Support. Untested patches do not include new features, schema changes, or changes to customer-facing user interfaces and APIs. Untested patches also will not change the look and feel of your site.
Untested Patch Delivery
As the name suggests, these updates do not undergo comprehensive QA testing and the customer agrees to assume any risk of regression issues caused by the update. The update will be applied to a clone site and the customer is expected to complete testing in a timely manner to mitigate this risk.
Oracle reserves the right to determine when this type of update can be delivered. These updates are reserved for emergency scenarios that are typically resulting in the customer's site being down. When a workaround to the defect has been identified Oracle will not build or deliver an untested patch to customers.
