The "CICS for System Programmer " is geared towards technical staff new to the CICS environment. In this course, the participant will learn how a CICS system is put together: resource definitions, system utilities both online and offline, System Initialization tables, CICS JCL, system datasets are subjects covered in depth in this course. We also discuss CICS storage management, CICS communications and CICS customization. At the end of this class, the attendee will have been exposed to almost everything that goes on in a CICS address space.

Mainframe Training Course outline

Module 1 - CICS Overview This module describe transaction processing within CICS; how is a transaction triggered, the various CICS components involved, the main CICS resources that are needed in order to make this process happen are all subjects covered by this module. It also discusses some of the software processing involved in making transactions work in CICS; CICS domains and TCB's are introduced in this chapter. Module 2 - Resource definition. This chapter discusses the entire process of defining resources in CICS using both the online and offline utilities. Performance issues are discussed when we cover the SIT table. Module 3 - CICS System Preparation. This chapter is about CICS system data sets and their use. This is also the place where the participant will learn how to define CICS system logs and MVS logstreams. Module 4 - Initialization & Shutdown. In this module, we discuss initialization and shutdown processes, the various types of START parameters, the DFHRMUTL utility used to modify the type of startup CICS will be doing Module 5 - CICS Storage. This module discusses storage management in CICS, the various page pools (DSA's), the storage protection facility and transaction isolation. Module 6 - CICS Communication. This module discusses the various communications facilities available in CICS. MRO, ISC, DEC support, WEB interface, 320 bridge are all introduced here in an attemp to provide a total picture of what CICS can do. Module 7 - Online tools. This chapter introduces the system programmer to the various online tools available in CICS. CEMT, CECI, CMAC, CEDF, CEDX are just a few of the transactions discussed in this chapter. Module 8 - CICS Offline Utilities. All CICS utilities will be presented here with an opportunity to try most of them. Focus will be on the following utilities: DFHSTUP, DFHJUP, DFHLGCNV, DFHMNDUP, DFHCSDUP, DFHTU620, DFHDU620, DFHEISUP, DFHBMSUP, transaction Isolation & Storage Protection, and more. Time will also be spent on some CICS on-line utilities like CETR, CEDX, CIND and more. Module 9 - CICS Customization An introduction to the various ways to customize CICS; User-Replaceable Modules, Global User Exits and Task-Level Global exits are covered in this chapter.
