Configuring a secure predefined IPIC connection (SC02)
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.
The following figure shows the topology used in this scenario:
Note: This scenario uses CICS Transaction
Gateway connecting to CICS Transaction
Server V5.3 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.
| Component | Parameter | Where set | Example value | Matching values |
|---|---|---|---|---|
| CICS TG | APPLID 1 | PRODUCT section of ctg.ini | MYAPPL | This value must be the same as 6 |
| CICS TG | APPLIDQUALIFIER 2 | PRODUCT section of ctg.ini | MYQUAL | This value must be the same as 7 |
| 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 | |
| RACF | User ID for user security | Client application | USERID | |
| RACF | Password for user security | Client application | PASSWORD |
