Distributed FileManager/MVS

Distributed FileManager/MVS uses the Distributed Data Management (DDM) and Advanced Program to Program Communication (APPC) protocols. DDM enables like and unlike computer systems to share file systems across a network. APPC manages peer-to-peer network conversations between application programs.

Distributed FileManager/MVS enables your z/OS system to act as a server to remote client systems. Distributed FileManager/MVS is designed to work with operating system platforms that support DDM client requests.

With Distributed FileManager/MVS, you can remotely access data on z/OS systems from the following IBM® systems, or their equivalent:

Workstations running the OS/2 operating system. Distributed FileManager/MVS on the OS/2 is called DFM/2.
AS/400® midrange computers running the OS/400® operating system. Distributed FileManager/MVS on the OS/400 is called Source OS/400 DDM.
Computers running the AIX® operating system.
