I run Datacom Server batch utility, SVCOMPR, to stop CA Datacom Server on the mainframe but nothing happens.
It looks like there is a communication issue between my batch job and Datacom Server.
I run SVCOMPR using APPLID= ... ,
SERVERNAME=my Datacom Server jobname ,
EOJ
CA Datacom Server has been started using PROTOCOL=TCP.
Run SVCOMPR using HOSTNAME=value from Datacom Server TCPIP_HOST and
PORT=value from Datacom Server TCPIP_PORT
