Price: $1625.00

Course Code: XP1020


Audience

Application developers, mainframe support staff, and systems programmers.

Description

XPEDITER/CICS is a debugging tool that lets you analyze, test and debug CICS applications running in a CICS environment. You will learn how to view and alter test profiles, interrupt a running program and examine storage, step through a program line-by-line, animate program execution, restart program execution at a different instruction, trace logic flow, bypass unnecessary program code, monitor, display and modify program variable contents, and more.This course uses a variety of CICS COBOL programs to illustrate the debugging of various abends and logic errors, including CICS programs with START, LINK, XCTL, and triggered CICS programs. This course focuses on debugging and analyzing COBOL/CICS applications. It is written for Xpediter/CICS Release 8.2. Earlier releases are also available.Lecture and extensive hands-on workshops reinforce the lectures and demonstrations.

Objectives

Upon successful completion of this course, the student will be able to:

  • Compile programs for use with XPEDITER/CICS
  • Use XPEDITER to analyze and debug CICS programs, ranging from simple ASRA (S0C7) abends to more complicated abends involving LINKed programs, XCTLed programs, non-terminal STARTed tasks and non-terminal triggered programs started from DCT triggers and MQ triggers
  • Use XPEDITER/CICS primary and line commands to: set breakpoints, examine and modify data, alter program logic, troubleshoot program errors, analyze the execution of your programs, and more
  • Use XPED and XPSP transactions to trouble shoot errors and follow program logic
  • Setup and use test scripts

Prerequisites

Students need to be able to use TSO and JCL and write COBOL/CICS applications.
