Issue/Introduction

Is  the CACHE parameter required in the GSO MUSASS definition ACF2/CICS or ACF2/IMS are also being used?

Environment

Release : 16.0

Component : CA ACF2 for z/OS

Resolution

The musass CACHE should only be used if you are not using a MUSASS interface like ACF2/CICS or ACF2/IMS.
Both interfaces provide cache processing internally to the interface.
Running a MUSASS that doesn't have a formal interface may provide faster resource validations if Musass cache is active.
It will provide previously accessed permissions without going through the full validation.
