Configuring a secure predefined IPIC connection (SC02)

Edit online

You can configure a secure predefined IPCONN for your IPIC connection between CICS® TG and CICS TS.

A predefined IPCONN provides a more secure environment and can prevent unwanted IPCONN autoinstall requests. To configure a secure predefined IPCONN for your IPIC connection between CICS TG and CICS TS, follow the instructions in this scenario.

Figure 1. Topology used in scenario SC02
This figure shows Windows Java client connecting to CTG over TCP/IP and CTG connecting to CICS TS over IPIC.
Note: This scenario uses CICS Transaction Gateway connecting to CICS Transaction Server 5.3 over IPIC in remote mode. You can run this scenario with other versions, but the illustrations and samples might vary. For the minimum requirements, see Prerequisites.

This scenario uses the default name ctg.ini for the configuration file.

Table 1. Values used in this scenario

CICS TG Server name IPICSERVER section of ctg.ini CICSA  
CICS TG Hostname IPICSERVER section of ctg.ini cicssrv2.company.com  
CICS TG Port  3  IPICSERVER section of ctg.ini 50889 This value must be the same as  5 
CICS TS TCPIPService  4  TCPIPService definition SRV50889 This value must be the same as  8 
CICS TS Portnumber  5  TCPIPService definition 50889 This value must be the same as  3 
CICS TS APPLID  6  IPCONN definition MYAPPL This value must be the same as 1 
CICS TS Network ID  7  IPCONN definition MYQUAL This value must be the same as  2 
CICS TS TCPIPService  8  IPCONN definition SRV50889 This value must be the same as  4 
RACF® User ID for link security IPCONN definition in CICS TS LINKUSER
