Distributed Data Access with DFSMSdfp

In the distributed computing environment, applications must often access data residing on different computers in a network. Often, the most effective data access services occur when applications can access remote data as if it were local data.

Distributed FileManager/MVS is a DFSMSdfp client/server product that enables remote clients in a network to access data on z/OS® or OS/390® systems. Distributed FileManager/MVS provides workstations with access to z/OS data. Users and applications on heterogeneous client computers in your network can take advantage of system-managed storage on z/OS, data sharing, and data security with RACF®.

You should understand the following terms used in this chapter:

Client/server: A distributed application design model in which the front-end transaction (the one that initiates the conversation) is called the client and controls the course of the conversation. The server receives a request from the client, processes it, and returns the results.
User: Any person or application that issues or receives commands and messages to or from the information processing system.
File: A collection of related data that is stored and retrieved by an assigned name. Data set in z/OS is equivalent to file in other environments.
