Setup Multiple TCP/IP Address Spaces

If your z/OS environment has multiple TCP/IP stacks and you want to ensure that CCITCP or CCITCPGW only binds to one of the stacks, you should use the PROTOCOL statement to define which TCP/IP stack to bind to. This is done by using *tcpip-job-name in the netdata parameter of the protocol. If your TCP/IP jobname is TCPIP1, your protocol statements should be coded as follows:

PROTOCOL(TCPIPGW,*TCPIP1:7000,01,CCISYSA)
PROTOCOL(TCPIP,*TCPIP1:1202)
