Defining VTAM Resources for Systems Using SNA

You are required to configure VTAM resources only if your environment uses SNA.

To set up the environment for SNA, you have to define a VTAM APPLID. This enables mainframe to mainframe communications through SNA.
SNA communication is supported for the following cases:
  • Platform Server for z/OS to Platform Server for z/OS file transfers
  • ISPF communication to the Platform Server for z/OS started task
  • Batch communication to the Platform Server for z/OS started task
