Dynamic PU definition (DYNPU operand)

The DYNPU operand enables PUs for type 2.1 peripheral nodes to be created dynamically on the VTAM® host accepting an incoming call. Code DYNPU=YES on the GROUP definition statement in an NCP, external communication adapter (XCA), or channel-attachment (CA) major node.

A switched PU is dynamically created when a calling PU cannot be identified by VTAM during a switched dial-in operation. VTAM uses the model PU definition in the model major node to define the characteristics of the PU.

Note: The DYNPU operand is ignored if a configuration services XID exit routine is active when a dynamic PU is needed. The exit routine determines whether a PU will be dynamically defined.
