In an INET environment, no action is necessary. In a CINET environment, for the command to communicate with a particular stack, the TCPIPjobname should be set in the appropriate resolver configuration file or data set. Make sure that the TCPIPjobname statement in the appropriate resolver configuration file or data set is correct and resubmit the command. For more information about the search order for locating the resolver configuration file or data set, see the z/OS Communications Server: IP Configuration Guide. The DISPLAY TCPIP operator command can be used to display all started TCP/IP instances and their jobnames. The TCP/-a command options can be used to explicitly select a TCP/IP instance by specifying its jobname.
