CICS Socket Interface - Tips and Techniques - Appendix

IBMLink ASKQ Library Item RTA000086732, which discusses the DELAYACKS PORT or GATEWAY option.
NERDC CICS assembler application program DCNEIP00 used to check and/or restart the CICS socket interface via an INQUIRE TASK looking for the supplied CSKL listener. This program utilizes a LINK to IBM supplied program EZACIC20. We run this program in all local CICS regions containing the CICS socket interface via "NEIP CHECK\" (without the quotes) in a sequential terminal at CICS startup, and "NEIP CANCEL\" at shutdown. The REGS register equates macro used in this program is also available.
NERDC CICS assembler sample security exit program EZACICSE used by the CICS Socket Interface via the SECEXIT configuration option. This is a "stripped down" version of our program, but should at least be a good starting point.
NERDC CICS Check CICS Socket Interface AIX CGI programs cksock.c and sockets.c based upon the IBM sample programs supplied in the IBM Redbook "Accessing CICS Business Applications from the World Wide Web", SG24-4547, and NERDC CICS socket assembler program DCSOKT00 invoked via the cksock.exe CGI program. The programs cksock.c and sockets.c are compiled to build the cksock.exe CGI program with these commands on AIX:
```
cc -c sockets.c

cc -o cksock.exe cksock.c sockets.o
```
You'll need to move cksock.exe to a valid directory accessible and executable from your Web server, after a successful compile. The SOKT transaction identifier will need to be defined to the CICS PCT to invoke DCSOKT00, which needs to be defined in the CICS PPT, and assembled as a CICS socket application program, by adding a SYSLIB DD for DSN=hlq.SEZATCP to your linkedit step with an INCLUDE SYSLIB(EZACICAL) to your linkedit SYSIN DD. Note that all of the above programs "need work" - but at least they're "free" and "open source". To see these programs in action, try URL:
