+ Guide to use a Mainframe on Windows Operating System
5 lectures 14:20

We need three things to work on a Mainframe Computer. We need a Mainframe Computer Hardware. Then we need an Operating System to install on it and then we need a Terminal to connect to the Mainframe. The Mainframe Hardware can be emulated using the Hercules Emulator. Hercules Emulator is a Software that behaves like a Mainframe. Then we can use the OS/VS2 operating system which is a FREE operating system for Mainframes. For a Terminal we can use a 3270 Terminal Emulator.

In this lecture the full procedure to download the softwares required to work on a Mainframe is explained. The software MVS Turnkey 3.8j system is also explained. All the material required to take this course is explained as well.

Preview 04:29

The full process to install the softwares to work on a Mainframe is explained in this lecture. The procedure is extremely simple. The cryptoTerm can be easily installed by just launching the installer. The MVS Turnkey system just needs to be extracted and the console mode should be switched on.

Installation of the software
01:08

Since the softwares are now installed we can boot the MVS up and use it. The act of booting up MVS is called Initial Program Load (IPL) on Mainframes. The full process of IPL is explained in detail in this lecture.

After the IPL is over we will connect to it using CryptoTerm Terminal emulator. Once the login screen arrives we will logon to the TSO environment. TSO stands for Time sharing Option. The username for MVS is HERC01 and password is cul8tr.

Sometimes the Login screeen does not appear. You will see the turnkey symbol without the login option. In that case you can just click on anywhere on the screen and press the enter key. Then enter the username HERC01. It will then ask you for a password. Enter CUL8TR and press enter key again. You will then be logged on to the MVS. This procedure is also explained in this lecture.

Booting up MVS and logging on to TSO
04:28

Once the work we need to do on a Mainframe is complete we can logoff from the system. We can use the logoff command to accomplish this. The logoff command is entered on the READY prompt.

To shutdown the system we have to enter shutdown on the READY prompt and then press enter. This will submit the shutdown job which will shutdown the system. After submitting this job we should ideally logoff from the system using the logoff command. The shutdown process will start and it will automatically close the MVS command prompt once it is over.

Logoff from TSO and shutting down the MVS
02:09

The previous lectures demonstrated how you can run a Mainframe on your own personal computer. When you work for a company then you will be provided with an IP address and a port number to connect to a Mainframe. You will also be given a username and a password to logon after connecting to it.

In that case you just need a Terminal Emulator to connect to a Mainframe. You have to enter the IP address and port number to connect to the mainframe. Once you are connected you can enter the username and password to logon to the TSO environment.

This article explain in detail the entire process to connect to a Company's Mainframe.

+ Guide to use a Mainframe on Ubuntu
2 lectures 06:13

In this lecture, I will show you how you can Install and use MVS Turnkey system on Ubuntu. MVS Turnkey system can be just extracted and run on Ubuntu. We can then connect to it using c3270 emulator. This lecture explains the whole procedure in detail.

Install and use MVS Turnkey system on Ubuntu
03:55

In this lecture i will show you, how you can connect to a Mainframe using c3270. In Ubuntu you can install c3270 using the command "sudo apt-get install c3270". For connecting to your Mainframe give command "c3270 ip address : port number". You will then be connected to your Mainframe.

Preview 05:11

To login to your mainframe, you need to have a username and an initial password. This initial password has to be changed during the first login. Once you login you will be faced with a READY prompt. Some systems have automatically enabled the ISPF command while login. So you will get an ISPF panel after logging in. This lecture explains the login process in detail.

Preview 02:09

Either you interact with it directly or you can interact with it using batch mode. The batch mode will use JCL to execute TSO commands. To interact with TSO directly you can use either


  1. Line by line mode

  2. Full-screen mode


In line by line mode, you will enter a command and TSO will return the result back to you.

In full-screen mode, you will enter a command such as ISPF and OMVS that will start a fullscreen application. You will then use these apps to interact with TSO.


This lecture is a white screen animation video that will explain to you in detail all these modes along with examples.
