CP-CP Session Activation

The CP-CP session activation user exit, UACP, determines if a TPF processor is allowed to start CP-CP sessions. When no TPF processor in the loosely coupled complex has CP-CP sessions, UACP is called during cycle-up and when an APPN-capable link is activated while the TPF system is in NORM state.

Note:
If this user exit is coded to not allow CP-CP sessions on a processor, you can still start CP-CP sessions on that processor by issuing the ZNETW ACT command.

Input

CE1CPD
CPU ID of this processor (the processor that wants to start CP-CP sessions)
