I started working with Mainframe when I was 18 years old, I decided to create this course due to the lack of material there is and the large amount of knowledge and information that is lost as the years go by.
This course will teach us everything related to z/OS and how to work with the system. It is not necessary to have prior knowledge since we will start from 0. Still, I assure you that it will be interesting from the beginning for everyone even if you know Mainframe, since we will be polishing already acquired concepts. We will properly understand what the Mainframe is, how it works, and what it’s composed of.
We will see how important the Mainframe is for our economy and how heavily used it is today for corporations. I will tell you how to get free and legal access to a Mainframe with z/OS so that you can access it from your personal computer. So if you cannot try at work what we do in the course, you can try it in this environment. I will guide you to access this IBM system and how to install the tool to connect to z/OS. It also has the latest version of z/OS, no old versions where we do not have all the options and tools available.
Then we will see the most important components and how to work with them:
- Sysplex: By seeing the resources and components of a z/OS, we will see in detail what a Sysplex is and how information is shared.
- TSO: We will see what it is and how to execute commands.
- ISPF: We will see this tool in depth since it is very important. We will analyze the most important configurations and options, specially, we will go deeply into option 3. Utilities, where we will see how to create datasets, the primary and line commands when listing and editing datasets, option 3.4 DSList, etc.
- SDSF: We will also cover this tool in depth since it is used daily and it is becoming more important. We will analyze each panel and see all kinds of commands that we can execute, we will also see the logs and how to understand the information they show us.
- JCL: We will analyze the key scripting language used in z/OS, which is used by jobs, users, and tasks to handle and use system resources and execute programs.
I hope you enjoy it and this course helps you.
I will be available and respond quickly to emails, you can contact me if you have any need.
Thank you so much!
All the best!!!
