Subject:      CICS EXCI Interface / Connector
Content-Type: text/plain

We have successfully web enabled CICS applications with 3270 logic and can
utilize both TN3270 or a browser for the applications. Now we want to
develop a proof of concept application to displace a Windows NT web server
application by utilizing the S/390 for the web presentation. Our S/390
configuration is OS/390 2.5 (CICS TS and Domino Go Webserver). I would like
to locate a SME or reference who has successfully implemented a solution for
building and serving dynamic HTML pages with DGW as the presentation layer
for CICS business logic. IBM has been unsuccessful in locating a resource.
The CICS application does NOT include any 3270 business logic.

My initial proof of concept design is to use the CICS EXCI interface to /
from CICS passing a commarea which contains the data elements for the
dynamic HTML pages. The EXCI interface appears to be simple with six basic
commands but we have no expertise with the EXCI interface on staff. Some
initial concerns include capable throughput, CICS  dynamic transaction
backout and security. The programming language for the EXCI interface
program could be COBOL or REXX.

Do you have any experiences the EXCI interface?

Do you have a better solution for dynamic HTML and CICS on S/390?
