Publisher: O'Reilly Media
Released: July 2000
Pages: 414

CICS is an application server that delivers industrial-strength, online transaction management for critical enterprise applications. Proven in the market for over 30 years with many of the world's leading businesses, CICS enables today's customers to modernize and extend their applications to take advantage of the opportunities provided by e-business while maximizing the benefits of their existing investments.

Designing and Programming CICS Applications will benefit a diverse audience. It introduces new users of IBM's mainframe (OS/390) to CICS features. It shows experienced users how to integrate existing mainframe systems with newer technologies, including the Web, CORBA, Java, CICS clients, and Visual Basic; as well as how to link MQSeries and CICS.

Each part of Designing and Programming CICS Applications addresses the design requirements for specific components and gives a step-by-step approach to developing a simple application. The book reviews the basic concepts of a business application and the way CICS meets these requirements. It then covers a wide range of application development technologies, including VisualAge for Java, WebSphere Studio, and Visual Basic. Users learn not only how to design and write their programs but also how to deploy their applications.

Designing and Programming CICS Applications shows how to:

  • Develop and modify existing COBOL applications
  • Become familiar with the CICS Java environment and write a simple Java wrapper for a COBOL application
  • Develop a web front end using servlets, JSP and JavaBeans.
  • Link the web front end to an existing COBOL application using CORBA
  • Write a Visual Basic application to develop a customer GUI
  • Link an existing COBOL application using a CICS Client ECI call
  • Develop a Java application using Swing as an MQSeries Client
  • Use the MQSeries-CICS bridge to access an existing COBOL application

Whether for working with thousands of terminals or for a client/server environment with workstations and LANs exploiting modern technology such as graphical interfaces or multimedia, Designing and Programming CICS Applications delivers the power to create, modernize and extend CICS applications.

Designing and Programming CICS Applications Review

By Axel Schwarzer

from Undisclosed

Comments about O'Reilly Media Designing and Programming CICS Applications:

If you are new to Java(Script) and that kind of programming this book won't help. It is limited to descriptions like "do a click here and one there and you're done": the backgrounds became not clearer to me. Instead of explaining pull down lists which change with every release the book would have benefitted from diagrams which show the relationship between the java parts.

Some parts were superfluous: handing over a clear error message with description to the user doesn't need to be mentioned at all, it's quite normal and doesn't need to be stressed more than once.

Although I knew that IBM was involved writing this book I was astonished about the frequency their products were mentioned. If it is essential for my programming success to use Version x.y.z.a.b.c because x.y.z.a.b.d won't work then I will continue searching for other solutions.

I found two or three minor typos i some illustrations. If you are new to the theme it is difficult to distinguish between the illustration and the text: which is the right one?

Designing and Programming CICS Applications Review

By Jim Gillard

Comments about O'Reilly Media Designing and Programming CICS Applications:

The book offers a reasonably good introduction to CICS programming on the mainframe. There are better and more complete guides.

The JAVA and VB WEB interfaces appear to be functional and can probably be used as templates for coding server side interfaces. There is a good section on setting up the Web Server components.

What I missed, and have been unable to find anywhere, was a presentation of using native CICS WEB or DOCUMENT calls. I guess I'm forced to examine the support packs which have limited explanations of what they are doing. Another missing piece is an example of modifying generated HTML from BMS maps to tailor the GUI generated into a more acceptable format. I've looked at the samples from the IBM seminars and they are too simplistic for most applications.

So, if you have an existing CICS app on which you want to quickly put on a GUI interface (customized), this book won't help and I don't know where you can find one.
