Mainframe Training : Job Control Language (JCL) And z/OS Utilities

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
