CICS for Applications Programmers (using VSAM)

Case Training
Bristol, Edinburgh, Leeds, London, United Kingdom

Course Format: Classroom | E-learning | Virtual Class | Online | On-site | Blended | Self-paced

Course Description:

'' This course provides the applications programmer with an in-depth knowledge of the CICS development process. It is aimed at programmers who need to code or support CICS application programs written in COBOL or PL1 that access VSAM Files.

Pre-requisites
The delegate should be familiar with the z/OS host environment, together with a working knowledge of either COBOL or PL/I program development using TSO / ISPF.

Course Objectives
The aim of this course is to provide the programmer, unfamiliar with CICS, with the necessary skills required to design, write, code and test both CICS programs and BMS Maps. On completion of this course the student will be able to:

describe the functions of a BMS Map
design, create, build and test a BMS Map
design and write a CICS program in either COBOL or PL1
use common CICS supplied transactions to view and maintain CICS resources
define resources to CICS using CEDA
access VSAM files from CICS programs
describe and use CICS Temporary Storage
describe and use CICS Transient Data
code exceptional condition testing
code programs which handle database backout and recovery
understand the concepts of Multi-Regional Operation
understand the concepts of WebSphere MQ and CICS interaction
