View all updatesEmuframe is a blog about IBM Mainframe (IBM Z) that I started in 2015. It focuses on the z/OS operating system.
Although the blog has evolved over time, the main goal was to teach how to perform tasks within z/OS.
Nowadays, I believe that focusing solely on z/OS while ignoring other technologies is “too limiting”.
In addition to teaching z/OS, I will research and teach how to use other technologies (Docker, Ansible, Python, etc.) and connect them with z/OS.

Description
This website contains documentation with the steps I follow to perform specific tasks. This does not replace the official documentation for each product. It is an additional resource to help make tasks easier to accomplish.
With the goal of having a resource repository, I will also include JCLs or REXX scripts that have helped me in the past.
Additionally, if I develop any web tools myself that I find interesting to include, I will do so.
This website does not store or distribute third-party software.

Software I Use
To emulate the Mainframe architecture, I use IBM Z Development and Test Environment Personal Edition on Ubuntu.
I use z/OS 3.1, specifically the ADCD z/OS V3R1 May Edition of 2024: ADCD z/OS V3R1 May Edition of 2024
