Defining connections in a generic resource environment

The VTAM® generic resource function can be used to balance session workload for APPC and LUTYPE6.1 connections.

Connections differ from terminal sessions in the following ways:

A connection can have multiple sessions. z/OS Communications Server's generic resource support creates dependencies, or affinities, to ensure that—once the first session is established—subsequent sessions to a generic resource are with the same member as the first session.
Either end of a connection can (in principle) establish the first session. Which end does (in practice) initiate the first session affects how connections should be defined in the generic resource environment.
Connections that fail, and require resynchronization, must be reestablished between the same members. z/OS Communications Server uses affinities to ensure that reconnections are made correctly.
