CICS Transaction Gateway V5 The WebSphere ... - IBM Redbooks

z/OS TCP/IP definitions
The TCP/IP address and host name (1) for the z/OS system are defined by
default in the PROFILE.TCPIP and TCPIP.DATA data sets. In our configuration
the data set was TCPIPMVS.SC66.TCPPARMS and it has members TCPPROF
and TCPDATA. These members have a lot of information, but we are only
interested in the HOSTNAME, and DOMAINNAMEORIGIN parameters in the
TCPDATA member and the HOME parameter in the TCPPROF member. In our
configuration, these parameters were as follows:
HOSTNAME wtsc66 is the host name of our z/OS system
DOMAINNAMEORIGIN itso.ibm.com is the domain name
HOME 9.12.6.6 is the TCP/IP address
Tip: You can also use the TSO command HOMETEST to verify the IP
configuration on your z/OS system.
CICS TCP/IP listener
In order to add a TCP/IP listener to CICS, we defined a TCPIPSERVICE called
PJA1TCP in the group PJA1GRP. PJA1GRP was in the startup GRPLIST for our
CICS region, so the listener will start when CICS is started. We used the
following command from a CICS terminal to define the listener (see Figure 5-3).
