A key objective of DFSMSdfp is to offer products that provide workstations with both record- and stream-oriented data access to z/OS® data. Workstations accessing z/OS data must have the capability of creating, reading, and writing data to the z/OS system-managed external storage. DFM is a DFSMSdfp client/server product that enables remote clients in your network to access data on z/OS systems.
