Master the Mainframe 2019 – Part 1 Challenge 1 Solution

What is Master the Mainframe Contest?

Master the Mainframe is an annual contest organized by IBM. In 2019 the contest started in September and ended on December 31. The Contest had over 30 challenges divided into 3 parts. In this series of posts, that I am writing on my blog, I will cover every single challenge in detail. Also, I have created a video for each challenge. So, if you like to watch the video instead then you can go to my YouTube channel called “Mainframe Nation”. The full solution to part 1 challenge 1 is linked below.

Part 1 of the contest covers the basics of a Mainframe. IBM has also made a lot of content for you to learn about Mainframes. It is recommended that you go to the below link and study it before proceeding further.

The above tutorial will teach you topics such as Specialty engines, Virtualization, Operating system, Middleware, ZOWE CLI etc.


Let’s Start Part 1 of Master the Mainframe contest 2019

The first step is to install a 3270 Terminal Emulator on your system. There are many emulators available on the internet. We will use Vista TN3270 emulator since it is the one mentioned on the Master the Mainframe website as well. You can download it from the below link

Download Vista TN3270 Emulator

First, Install and then open the software. You will then be presented with a screen like this:

In the Host IP, you have to enter the IP address of the Mainframe you want to connect to. And in the IP port field, you have to enter the Port number of the mainframe that you want to connect to. Below are the details for Master the Mainframe system:

IP address = 192.86.32.91
Port number = 23

So, enter the details and then click on the Connect button.

You will then be presented with the Logon screen.

Logon to the TSO environment by giving command

logon z51555
Please note that z51555 is my id. You have to enter your own Mainframe Id. 

for e.g. If your id is z52342 then enter "logon z52342" to logon to the Master the Mainframe system.

Going forward in this post, wherever you find z51555, replace it with your id.

Enter your password in the next screen.

Enter the password you received in your email
Enter the password you received in your email

Since this is your first time logging in, It will ask you to reset your password. A new message will be displayed “Your Password has Expired. Please Enter New password”.

It will ask for Verification once again. Enter the new password again and press the Enter key. You will then be logged in.

Reenter the new password again for verification

A new menu will appear which is known as the ISPF Primary Option Menu.

Function Keys

Before proceeding further, you have to remember some keys without which you won’t be able to work on your Mainframe. These are called the Function keys. They generally appear on the topmost line of your keyboard.

Function keys on a Keyboard

Below are the most used Function keys:

  • F7 – Move up
  • F8 – Move down
  • F10 – Move left
  • F11- Move right
  • F3 – Go back

Press these keys one by one and see what happens.

You can see these details at the bottom of the screen as well.

Navigating through the ISPF menus

Before you can proceed further you should know how to navigate through ISPF menus/panels. ISPF is a panel driven interface, what that means is, that you have to navigate through different panels to get your work done. You go to a panel by entering its number on the command line. On the top of the screen you can see “Option ===> _______________”

Command line or the Option line
Command line or the Option line

Here you have to give a number such as 3. Number 3 will take you to an option called Utilities.

0 — will take you to Settings.
1 — will take you to View.
2 — will take you to Edit….. and so on till 11.

There are even more options such as

SD — will take you to SDSF
U — will take you to Unix

You can see all the options listed by pressing the F8 key. Let us enter 3 and press enter.

Enter Option 3 for going to Utilities
Enter Option 3 for going to Utilities
We are now in the Utilities Panel
We are now in the Utilities Panel

So, to allocate, delete, rename data sets we can enter 2 on the option and press enter.
To go back you can press the F3 key. It will again go back to the previous screen. This is how you navigate through the ISPF panels.


Completing Challenge 1 tasks of Master the Mainframe

Submitting TSO job

Enter the following command on the Command line, that is “Option ==> ______________” and then press the ENTER key.

tso submit 'zos.public.jcl(part1)'
Allocate part1 data sets
Allocate part1 data sets
Enter 'a' when it asks you to Enter Jobname character
Enter ‘a’ when it asks you to Enter Jobname character
Job submitted
Job submitted

It will then show you MAXCC=0000. MAXCC stands for the Maximum Condition Code. Remember that a value of 0 means that your job has finished successfully.

MAXCC of 0000 means successful execution
MAXCC of 0000 means successful execution

Verifying that the JOB was successful

Now go to option 3.4 in ISPF.

Give 3.4 in the command line
Give 3.4 in the command line

In 3.4 give your username in front of the Dsname Level …

Give your username in the Dsname Level field
Give your username in the Dsname Level field

You will then see 5 datasets with your userid. This means that the step completed successfully.

Data set list with my userid
Data set list with my userid

Unix Directory List

Now again go to option 3.4 and then give the following in the Dsname Level field: /z/z51555

Find Unix files in option 3.4
Find Unix files in option 3.4

You will then see a list of all your datasets in the Unix environment.

z/OS UNIX Directory List

Unix Shell prompt

Press F3 to return to your 3.4 option. Then press F3 again to come back to ISPF primary option Menu. Here we have to give option ‘U’ on the command line. It will then open the Unix shell prompt.

Enter u to go to Unix Shell Prompt

Give the command “date” and press the ENTER key.

date command in Unix

The below command will copy the date into p1 dataset. So, give the below command and press the ENTER key:

date > p1

The cat command displays the content of the dataset. So, give the below command and press the ENTER key:

cat p1
Output of cat p1
Output of cat p1

The content of the p1 dataset will be displayed on the screen. Now we have to copy this dataset to another dataset using the copy command called cp.

cp p1 '//pds.data(p1)'

After that give the command:

cat '//pds.data(p1)'

Again you will see the content of the dataset ‘pds.data(p1)’. We can now exit the Unix Shell by giving the command exit.

exit
EXIT command to exit the OMVS
EXIT command to exit the OMVS

Verify the successful completion of Copy operation

Let us now confirm whether our Copy operation was successful or not. Go to option 3.4 and enter our dataset name ‘z51555.PDS.DATA’. Give v in front of the dataset to view it. It will then show a list of members. Give v in front of member P1.

View the member P1 inside dataset z51555.PDS.DATA
View the member P1 inside dataset z51555.PDS.DATA

If you see a screen like this, then your challenge was successful.

This is the data inside P1 member of the dataset z51555.PDS.DATA
This is the data inside P1 member of the dataset z51555.PDS.DATA

That is it all the challenges in the Part 1 has been completed. Let us now complete the final step to finish Part 1, which is a quiz.
