About DFSMS

The IBM SystemManaged Storage Migration Planning Guide advises RACF be used to control DFSMS functions. The RACF recommendation is there to advise the DFSMS client that only an external security package can be used to restrict DFSMS activity, and an SAF‑compatible external security product (such as CA Top Secret, CA‑ACF2, or RACF) is required to protect DFSMS functions.

CA Top Secret's philosophy of being SAF‑compatible allows this IBM use of SAF classes to be smoothly integrated into it.
