Abstract for z/VM: Connectivity

This topic collection provides an introduction to the facilities of IBM® z/VM® that allow z/VM systems, application programs, and guests to establish logical connections to other systems, application programs, and guests. It describes the following z/VM connectivity facilities:
  • Advanced Program-to-Program Communications / Virtual Machine (APPC/VM)
  • APPC/VM Virtual Telecommunications Access Method (VTAM®) Support (AVS)
  • Inter-System Facility for Communications (ISFCISFC)
  • Transmission Control Protocol/Internet Protocol (TCP/IP) for z/VM
  • Transparent Services Access Facility (TSAF)
  • z/VM virtual networks (guest LANs and virtual switches).
If you are: Refer to:
Responsible for planning and implementing networks for z/VM
An application programmer who uses APPC to write programs or a system administrator in charge of setting up virtual machines in which APPC applications will run
An application programmer who uses APPC to write programs The z/VM: CMS Application Development Guide, for information about:
  • The APPC/VM programming interface
  • The programming interface of Common Programming Interface Communications (CPI Communications), which is the communication element of the Systems Applications Architecture (SAA) CPI
A system operator or system administrator in charge of running the TSAF virtual machine
A system operator or system administrator in charge of running the AVS virtual machine
A system operator or system administrator in charge of planning and running ISFCISFC

Intended audience

This information is for anyone responsible for planning, setting up, running, and maintaining z/VM connectivity facilities.

You need to have a general knowledge of the z/VM system and a basic knowledge of application programming. Knowledge of Systems Network Architecture (SNA), TCP/IP, and VTAM concepts is also helpful.
