This intermediate course has been designed for application developers and analysts who design, code and debug CICS command level applications.
Delegates should have:
- A basic knowledge of CICS fundamentals, as taught in CICS V5 Fundamentals - WM851G.
- A working knowledge of the underlying operating system platforms.
- COBOL or PL/1 application development skills.
- A basic knowledge of application design and programming.
In this five-day, intermediate-level, instructor-led course, delegates learn to design, code and debug command-level CICS application programs for e-business or traditional environments.
The course begins with an overview of the CICS application programming environment and the design of CICS applications. Subsequent topics include debugging, working with CICS queues, front-end programming, basic mapping and event processing. In addition, optional units introduce topics such as CICS Web applications and business transaction services.
Hands-on exercises in COBOL or PL/I enable delegates to gain experience with CICS programming. Skills addressed in the exercises include using the CDEF utility to perform debugging, linking CICS applications to outside applications and writing sample programs.
Course objectives include:
- Design and develop application programs for CICS environments.
- Design applications with separate presentation and business logics.
- Describe the purpose of the CICS Clients.
- Code CICS commands.
- Pass and receive control between program modules.
- Describe and compare the CICS COMMAREA and the CICS channel and container interface.
- Prepare programs and run tests, including problem determination and resolution, using messages and online interactive debugging tools.
- Access and modify Virtual Storage Access Method (VSAM) files, DB2 databases, temporary storage, and transient data queues.
- Respond to normal and exception conditions from CICS commands.
- Send and receive basic mapping support (BMS) maps.
