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

5.1.2 Definitions checklist
84 CICS Transaction Gateway V5
The definitions we used to configure this scenario are summarized in Table 5-2.
Before you configure the products, we recommend that you decide on definitions
for each parameter listed. Reference keys shown in the Key column are assigned
to definitions that should contain the same value in more than one product. The
Example column shows the values we used in our configuration.

In addition, we also had to deploy our CICS COBOL application EC01 and
configure a DFHCNV data conversion template in CICS for use by this program.
Refer to Appendix A, “DFHCNV and CICS data conversion” on page 329 for
more details.

To configure a CICS TCP/IP listener to handle ECI requests, we first had to
confirm the following definitions were installed into CICS:
► SIT parameter: TCPIP=YES
► CICS-supplied Transient Date queue CIEO, in group DFHDCTG
► Transaction CIEP in group DFHIPECI
► Program DFHIEP in group DFHIPECI
All of these definitions are included in the list DFHLIST and so were activated in
our CICS region. The SIT parameter ISC=YES is not required for operation of
ECI over TCP/IP.
