Starting the CONNX CICS/VSAM TCP/IP Listener
The listener process waits for and verifies connections with client machines.
1. After logging on to the CICS region, enter nx01 start, and press <Enter>.
The CONNX TCP/IP Listener starts.
2. Verify start by typing CEMT INQ TA. Press <Enter>. The screen displays a list of transactions currently running. Verify that Tas(0000xxx) Tra(NX00) is listed as one of the transactions.
3. For CICS/VSE 2.3 and below installations, starting and stopping the CONNX CICS/VSAM TCP/IP Listener requires a dedicated terminal for the CNXSIGN external security interface program.
For example, if NX01 START is issued from a CICS/VSE 2.3 terminal session, followed by a CEMT INQ TA, the terminal will lock until the CONNX Listener transaction is stopped with the NX01 STOP command.
Alternatively, the CONNX CICS TCP/IP Listener can be started from the VSE console and stopped from a CICS/VSE 2.3 session.
