Implementing Security for DFSMS › DFP 3.0 and DFSMS › DFP Components

DFP Components

The components of DFP Version 3 provide:

• A z/OS subsystem honoring standard subsystem interfaces for communication, and the System Authorization Facility (SAF) for all security controls. (This makes SMS information fully accessible by other system software components.)
• A real‑time handler of data set classification (from a storage, not a security, perspective) and new data set allocations on SMS controlled volumes.
• A DASD device grouping facility.
• A facility that stores additional information in the ICF catalog, the VVDS, and in the VTOC entries of SMS controlled data sets.
• A facility that can help reduce JCL coding requirements.
• A facility to define performance preferences for allocations.
• A source of information for system programs that request it.

SMS brings new information about DASD data sets that it manages and provides new services to programs and systems that are prepared to use that information.
