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.
