An LU-LU session must be established before data can pass between a TPF
application and a logical unit.
The following list different ways to establish a session:
- A secondary LU is defined as permanently in session with a TPF application
(VTAM AUTOLOG facility).
- A remote LU requests a session with a TPF application from its control
point.
- The TPF operator requests a session be established using the ZNETW ACT
command. (This is valid only for APPL to APPL sessions.)
- A TPF/APPC session is activated with an ALLOCATE request. See TPF Advanced Program-to-Program Communications for more information about TPF/APPC.
