SYSTEM 2000 Web Interface to CICS
SYSTEM 2000 is taking advantage of IBM's CICS Web Enablement to provide Web access to SYSTEM 2000 databases through CICS. With the new SYSTEM 2000 Web interface you have direct access to SYSTEM 2000 databases from an internet Web browser. S2OP, S2KU and, in Version 1, all other CICS transactions are Web-aware, meaning they use the new EXEC CICS commands that allow communication with Web browsers. Anything that these transactions can do within CICS they can also do from a Web browser.
Features of the Web Interface
These are some of the reasons users are finding it so easy to use CICS on the Web:
You need to be running Version 1 or Release 12.1 of SYSTEM 2000 software, and CICS Transaction Server 1.3 (or above) with a minimum put level of 0008.
For Your Existing CICS PLEX Applications
There are two ways to provide CICS transactions on the Web: you can use the 3270 Bridge, or you can write web-aware transactions.
3270 Bridge Transactions
The 3270 Bridge is the quickest and easiest to implement.
Simply, it takes the 3270 formatted output and presents the "screen" to the browser.
Non-BMS screens mainly use the HTML tags <PRE> ...text... </PRE>.
BMS maps must first be processed with a utility program to create the HTML
template members for each map used in the Web environment.
The primary advantage of the 3270 Bridge is that minimal
changes to your existing 3270 applications are required.
Web-Aware Transactions
Web-aware applications are more powerful and flexible than the 3270 Bridge. They know they are communicating with a Web browser and not a 3270-type terminal. In CICS TS 1.3 the new EXEC CICS commands in the API handle all communication with the browser. New and existing applications that already have their presentation logic separate from their business logic are good candidates for taking advantage of the new API.
