Service Packs and Quick Fix Enhancements (QFE)
PeopleSoft always runs certifications on the latest SQL Server service packs as they become available. Service packs contain large number of improvements and have been tested extensively by Microsoft.
A QFE is a fix intended to solve a specific problem that's usually documented in a Microsoft Knowledge Base (KB) article. PeopleSoft doesn't run certification tests for any particular SQL Server QFE, but considers them to be supported when they're recommended by Microsoft to solve specific problems. However, to install a QFE, PeopleSoft recommends appropriate testing before applying it to a production environment. It's important to take into consideration that a QFE is an enhancement targeted to solve a specific problem. “Secondary effects” as a result of its installation can be determined only with proper testing.
PeopleSoft does not distribute SQL Server QFE software; please contact Microsoft to determine if a QFE is required, and for instructions on how to download the software.
