Build a foundation in Mainframe with this tutorial for beginners.

You will Learn:

  • What a JCL is.
  • The various Statements and how to code them in a JCL Program.
  • Running and diagnosing JCL programs on a Mainframe
  • Procedures used in JCL
  • Different utilities of JCL

A Powerful Skill at Your Fingertips  Mainframe is extensively used in large corporations which deal with huge amount of data every day. Over 70% of the global Fortune 500 companies use Mainframe to run their business for everything from cloud to mobile to big data and analytics. Now, there are 1.1 million customer transactions per second on Mainframes compared with just 40,000 searches on Google per second. IBM is the leading manufacturer of the Mainframe Systems.

Content and Overview  Through this course, you’ll learn about the JOB Control Language on the Mainframe system.

Starting with an overview of the JCL, this course will take you through the types of statements, Procedures and Utilities used in JCL.

With these basics mastered, the course will take you through the different operation that you can do on a dataset, will introduce the GDG and its use in the Mainframe systems.

Upon completion you will be literate in JOB Control Language, understand how a JCL program is coded and executed on a Mainframe.

NOTE: This is a JCL Programming course. It does not cover Programming in COBOL. However, execution of Cobol programs using JCL is covered in this course.

Who is the target audience?
  • IT professionals who want to make a career in Mainframes.
  • Mainframe Professionals who want to brush up their knowledge about JCL.
  • JCL revision before your interview
