Explanation
 The operator entered a SET command to define session
values, but the logical unit (LU) for which the session values are
being defined is not in the Advanced Program-to-Program Communication
(APPC) configuration.
 The LMADD and LMDEL statements in the
APPCPMxx member are no longer valid.  Session-limit values can be
changed by entering the VTAM® MODIFY
CNOS and MODIFY DEFINE operator commands, or by modifying the VTAM APPL definition statement
and then restarting APPC/MVS. The VTAM MODIFY
CNOS and MODIFY DEFINE operator commands are available in VTAM Version 3 Release 4 for MVS/ESA.

Operator response

the active LUs. Then enter the SET command to define session values
for a defined LU.

System programmer response
 Check the LMADD statement in the
APPCPMxx parmlib member to make sure that the ACBNAME specified is
already in the APPC configuration.
