In the past it was difficult to get access to a Mainframe. However, today you can connect to a real Mainframe free of cost. In this post, I will list out multiple ways to get a Mainframe access – FREE and PAID both. So let’s start.
1. FREE – Get a Free Mainframe access
1.1 Master the Mainframe 2020 Contest – The BEST option !!!
Every year IBM organizes Master the Mainframe contest. This contest starts in September and ends in December. However, you can complete the contest year around. To complete the contest you get access to a Mainframe. You have to connect to that Mainframe and complete all the challenges. There are two ways to register for the event and get a Mainframe access. One is to Register as a student and second is to register as a Learner. Both, the ways are listed below in detail.
Register as a Student
To register go to the link: https://masterthemainframe.com/
There you can click the button called “Get Started”. It will take you to a new tab. In that tab, you have to create a new IBM ID. This ID will help you in participating in the 2020 contest. You will get an IP address to connect to your Mainframe. Plus, you will get a username and password as well.
If you are not a student then do not worry, IBM has got you covered. IBM provides you with what they call a Learning system.
Learning System on Master the Mainframe contest
If you want to learn about Mainframes, then this option is for you. Anyone can register for this Mainframe.
Go to the following link: https://www.ibm.com/it-infrastructure/z/education/master-the-mainframe
Here click on the button called “Get Started”.
It will take you to a new tab where you have to create an IBM ID. You will participate in the MTM contest using this IBM ID.
After creating the ID you can go to the below link to start your Master the Mainframe contest:
You will be presented with different challenges. In Level 1.2 challenge, you will get your Username and password to connect to the mainframe.
For the 2020 contest the Mainframe system details are:
IP Address: 18.104.22.168 Port: 623
Below is the login screen for this system:
Difference between Registering as a student and Learning system
There is literally no difference between the two. Both will give you access to the same system. The IP address will be the same as well, because it is the same mainframe that you are connecting to. Only the registration process is different. That is because, only students are eligible to win prizes. So students have to register separately. All non-students can register and solve the same contest, but they will not be awarded any prizes for this contest.
I have also created a series of posts on Master the Mainframe contest. You can find the full solution of Master the Mainframe 2019 contest in these posts. Visit the below link to read these posts:
1.2 Coursera Courses – Courses that provide you with a Mainframe Access
IBM has also released some Mainframe courses on Coursera website. The instructor for these courses is Jeff Bisti. These courses also give you Mainframe access. I have listed the courses below.
1.2.1 COBOL Programming with VS Code
This is an Introductory COBOL course. It is FREE of cost. You will need to pay only if you want a certificate for this course. The course gives you Mainframe access. Go to this link to enroll for this course: https://www.coursera.org/learn/cobol-programming-vscode
To get Mainframe access to this course you need to fill up a form at this link: https://www-01.ibm.com/events/wwe/ast/mtm/cobolvscode.nsf/enrollall
Once submitted you will receive an email with IP address and your username for the system.
The Mainframe system details for this course are:
IP Address: 22.214.171.124 Port: 623
Generate Password for the system
You will not receive password for your userid. For generating your password, you have to login to this Slack Channel. Use the below link to join the slack channel.
After logging in you will see an app called ‘zih’. Click on it and say anything you want such as ‘hello’. It will then ask your email address and the userid that you have received. Enter these details and then you will get your password.
Login via 3270 Emulator
Here is how the login screen looks like on this Mainframe:
Login via Visual Studio Code
You can also connect to this Mainframe using VSCode extension. For that you have to use the below URL on VSCode.
If you are not aware about ZOWE on Visual Studio Code then follow the below steps to connect using Visual Studio Code.
ZOWE Explorer extension on Visual Studio Code
Install extensions first – Zowe and IBM Z Open Editor
First install Visual Studio Code if you do not have it installed already. After that you have to install an extension called Zowe Explorer.
Also, install another extension called IBM Z Open editor.
After installation, you will see an icon on the left sidebar, saying Z. Click on it.
Create a new connection profile
You will then see 3 columns saying DATA SETS, UNIX SYSTEM SERVICES (USS) and JOBS.
Click on DATA SETS and then click on the + icon to connect to your mainframe
Give any name and then press the ENTER key.
I am naming my connection as “cobol course mainframe connection”. You can name it anything you want. Now again press the ENTER key. It will ask for the profile type. Give zosmf and press ENTER again.
In the next screen it will ask for the URL of the connection. Give the below URL:
In the next screen give the username that you received in your email. My username is z81812, hence i have entered that.
You will now see a new connection called ‘cobol course mainframe connection’ under DATA SETS. You are now connected to your mainframe using Visual Studio Code.
Dataset operations using ZOWE
All the major operations on a Mainframe are possible using VSCode. You can create a new dataset, edit a dataset, and delete a dataset as well. Also, you can submit JCLs and the resulting Job details in spool can also be seen.
To do DATASET Operations click on DATA SETS and then click on the ‘search’ icon on your connection name.
Now I can edit any of these datasets by clicking on them.
Submit a JOB using ZOWE
To submit a JCL I can just go to the JCL dataset, right-click on it and select the Submit Job option. In the below image I have a JCL that compiles a COBOL program. I am going to submit this JCL.
On the right bottom corner, it will confirm that the JOB has been submitted and will display the JOBID as well.
Now to see the Job output just click on the JOBS options in the left sidebar.
Here also you have to follow the same procedure. Just click on + icon and then click on the connection name that you have created before. It will then list all your JOBS in SPOOL. You can see the JESJCL, JESMSGLG, and other details using this option.
These are just a few options out of many that are available using ZOWE. I hope this section was informative for you. If you face any issues then please comment about it in the comment section.
1.2.2 IBM z/OS practitioner course
This course is also available on Coursera. It is a collection of 3 courses. You will not get real Mainframe access but an IBM Remote Lab Platform access. You will also need to create an IBM ID before you can access this environment.
To create an IBM ID go to this Link first:
After you create your IBM ID go to the below link and register for the course.
You will see 3 courses in this one course:
1. Introduction to Enterprise Computing
2. Getting Started on Mainframe with z/OS commands and Panels
3. Basic System Programming on IBM Z
In the second course titled “Getting Started on Mainframe with z/OS Commands and Panels” you will find a lecture called “Course Kit / Exercise guide – Required Download for Lab Exercises”. This lecture contains your Lab details.
After reading that lecture you can go to the next lecture called “Exercise 1: System familiarization“. There you can click on “Launch Lab” and a new window will open which will have your Lab.
Get your Userid and Password details for the Mainframe access
Now to get your user id and password details, click on the top left corner called “Course Lab kit”. It will open a new window which will have your username and password.
You will get TSO userid and password. Also you will get a password for logging into the Windows account of the Lab.
Click on MVS1 and then enter your TSO userid and password to login
This Mainframe will only work for 80 hours or 15 days, whichever is earlier. IBM does this to save their resources.
1.3 Older Mainframe system – Fandezhi system
Few years ago there used to be this system called Fandezhi Mainframe system. It was totally free for anyone to use. However, it was only meant for experienced users. So, you were not allowed to use this system for learning mainframes or training anyone. This is how the login screen looked like:
Users were able to generate their own TSO userid using the self help option.
This system is now closed forever. I have just included this option here for the sake of completion.
2. PAID – pay to get a Mainframe Access
2.1 Get Mainframe ID on rent
The title is self-explanatory. You can google search for “Mainframe Access for rent”. Once you search this you will get a list of vendors selling Mainframe IDs on rent. The average rate is around $50 per month. The biggest advantage of this option is that you will get access to CICS as well because none of the FREE options have CICS enabled.
2.2 ADCD System from IBM
ADCD is a short form for Application Developer Controlled Distribution. This system was designed by IBM for Application Developers. ADCD is a fully functioning z/OS that runs on your PC. It has an annual fee of $900. So, you have to pay IBM to get these files. Once you get these files you can run them using Hercules Emulator. This way you can run a fully-featured z/OS on your own Personal computer. Every single subsystem is available on this system. To know about it click on the below link.
I once messaged IBM support to get this system, but got no response from their side. The login screen of this system look like this:
3.1 MVS Turnkey System
MVS Turnkey is a ready to run Mainframe system for your Personal Computer. It has an older operating system called MVS 3.8j. Also, no installation is required for this system. So, you can just download the system and run it directly, no installation is required. The system can be downloaded from the below link:
You should download the latest version given at the end of the page, titled “tk4-_v1.00_current.zip“
After downloading just extract and run the file called “mvs.bat” and then connect to it using your 3270 emulator.
This system has a lot of disadvantages. First is that there is no ISPF on this system. Second, there is no DB2. Third there is no CICS as well. This is because all these are licensed softwares, hence none of these are available on this system. However if you have no other option then this will be helpful in learning about datasets and running COBOL programs.
3.2 Hercules Emulator
Hercules Emulator can emulate z/Architecture on your Personal Computer. It can also emulate older architecture such as s/370 or s/390. The Emulator can also run z/OS using ADCD files from IBM. MVS Turnkey system uses this emulator only to run MVS 3.8j. You can download this software from the below link:
This emulator will only emulate the architecture. You will need an Operating system which will be installed on top of this emulator.
In my opinion, the best option is to get a Mainframe ID on rent. This way you will have access to all the subsystems such as DB2 and CICS. You will also be able to run COBOL-DB2 programs on these Mainframes.
However, if you do not require these subsystems and only want to run COBOL programs, then Master the Mainframe System is the clear winner. This system provides you with the latest z/OS which has TSO, ISPF, COBOL, VSAM and DB2. You can run DB2 SQL queries on this system. However, you will not be able to run COBOL-DB2 program. There is no CICS access on this system.
I hope this post was helpful to you. If you enjoyed this post, I’d be very grateful if you’d help it spread by emailing it to a friend or sharing it on Twitter or Facebook. It may be helpful for them as well.
As a thank you for my efforts, you can also consider buying my course on Udemy, which is around $10 only. You will get 19+ hours of Mainframe tutorial which will teach you TSO, ISPF, JCL, COBOL, CICS, Unix System Services, and VSAM. You can follow this referral link to buy my course.
