APPC: Dependent LU Session Type Data Screen
The “APPC: Dependent LU Session Type Data” screen, shown in Figure
4-9, is used to configure session types for dependent LUs. Dependent
LUs can communicate only with other dependent LUs on a host
(Type 5) node. They always function as secondary LUs; that is, they
cannot initiate a session by sending a BIND. When a dependent LU
wants a session, it must send an INIT_SELF request to solicit a BIND
from the remote LU, or it must be configured to accept unsolicited
BINDs.
A dependent LU can participate in only one APPC session at a time, so
you must configure at least as many dependent LUs as you will have
active dependent LU sessions. After you enter the data into the “APPC:
Dependent LU Session Type Data” screen, press
[f6] (Save Data), and
then press
[f1] (Go To LULIST) to get to the “APPC: Dependent LU List
Data” screen.
