Note: Mainframe ID will not be provided with the course. You have to arrange your own Mainframe ID.

Welcome to the most detailed and elaborate course about Mainframe on the whole internet. The course offers exclusive content about Mainframe in movies and other media.

The course has been BESTSELLER since its launch in January 2017. It is the top reviewed and most sought-after course about Mainframe on Udemy. I made this course exclusively for UDEMY.  You will not find content like this on the internet.

This course also includes some amazing facts about Mainframes like FIFA world cup brazil used Mainframes to detect whether a goal has been scored or not, and the most recent New Jersey Unemployment department needs COBOL programmers during the COVID-19 corona crisis.


About Me:

I am the original creator of the Mainframe courses on Udemy. I have been creating content since January 2017. After seeing my success many other instructors and Training institutes have started their own courses. Most of these are training institutes that just launch courses to earn more and more money.

I am NOT a Training institute. I am an instructor on Udemy. Training institutes just launch many courses under many different topics to earn more and more money. They also have physical training institutes where they teach. They then create content and launch on Udemy to earn extra income.

I do not do this. I only create content related to Mainframes and Electronics. I create content exclusively for my website and Udemy.

You can go to my YouTube channel and you will find free content and courses worth many hours related to Mainframes.

I had 3 courses in 2017


2. JCL


I had announced that I will release 3 more courses soon


2. DB2 SQL


Other instructors started releasing courses under the same title as mine. They added some extra information to make their courses look better.

I have 8 years of experience in Mainframes. I was also the community partner for IBM Z day which was organized by IBM on Nov 21. More than 300 students from this course joined that event. You can search for IBM Z day and on the landing page of the event you will find “Mainframe Nation”, that is me.

So be rest assured that you are learning from an authentic Udemy Instructor and not from a Training institute.

Mainframe is extensively used in large corporations which deal with huge amounts 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 Mainframe Systems.

Content and Overview  Through this course of over 18 hours of content, you’ll learn about the Mainframes and establish an understanding of the mainframe system.

Starting with an overview of the Mainframes, this course will take you through the types of datasets, Operating systems, and data processing used on mainframes.

With these basics mastered, the course will take you through TSO commands, will introduce you to ISPF commands, allocation of datasets, and then the different operations you can perform on the datasets.

It will then cover JCL, VSAM, COBOL, and CICS.

Upon completion you will be literate in Mainframe terminology, understand how datasets are created, and how you can use commands to operate on the data in these datasets. You will gain enough knowledge to self-learn further Mainframe topics such as CICS.

You can view and review the lecture materials indefinitely, like an on-demand channel.
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
