Job Control Language (JCL) And z/OS Utilities

Mainframe Training Overview

This course is a combination of lecture, discussion and hands-on lab sessions.

First, an overview of JCL is given which describes the purpose of JCL, its relationship to the operating system, and the format / rules for coding.

Then, the JOB, EXEC and DD statements are covered extensively.

The purpose and use of each statement is described in detail; along with many parameters available to provide information to the operating system.

Procedures and several commonly used IBM utilities are covered in detail.

Recognize, analyze & correct typical ABENDs "caused" by JCL "errors".

Mainframe Training Learning Objectives

Upon successful completion of the course, each student will be able to -

  • Describe z/OS operating system functions
  • Describe Job Control Language statement syntax and format
  • Create and use the JOB statement and its parameters
  • Create and use EXEC statements and its parameters
  • Create and use DD statements and its parameters
  • Describe the need for and use JCL procedures
  • Create and use JCL procedures
  • Analyze and correct typical JCL ABENDs
  • Use the Sort utility and several other IBM utilities
  • Describe the function of JES
Mainframe Training Audience

This course is for entry level programmers or experienced information processing personnel who need an in-depth knowledge of JCL (Job Control Language).

Mainframe Training Prerequisites
