As a muscle memory check from things 33 years ago, I wanted to know how much the #ibm #mainframe under #zOS has changed from /370 back then.   Yes, we are now at #JES3 - and the new things for me were PDSEs and USS - feels weird calling #OMVS and having a #Linux environment #shell on the mainframe. Ah yes, we did not have #FICON either back then to define CHPIDs but the 3380 and 3390 were actually huge boxes connected via #bus and #tag cables. And of course #TSOE - with #ISPF. The TSO commands however look still very familiar. Same with procedures/modules in SYS1.PROCLIB, even with the #IEFBR14 "do nothing" program still very useful in #JCL. The University of Konstanz still had a #Comparex IBM compatible mainframe running, and I wrote a better version of the existing IRC client in REXX. I added the file transfer functions and fixed the EBCDIC-ASCII conversion. Those were the times.

Thrilled to announce that I've earned the IBM Z Xplore – Advanced badge! Through this program, I tackled complex mainframe challenges by applying critical thinking and leveraging diverse resources. I honed my skills in orchestrating system activities using Ansible and Zowe while working in Docker containerized environments. Along the way, I developed and debugged code in REXX, COBOL, Linux, and JCL, gaining a deeper understanding of enterprise computing. #IBMXplore #IBMZ #Mainframe

Starting my IBM z/OS Mainframe Practitioner Professional Certificate by the completion of 2nd course "Getting Started on Mainframe with z/OS Commands and Panels" from IBM through Coursera. This course helped me gain knowledge on: - Navigate through ISPF/PDF dialogs and use the basic ISPF/PDF functions and the ISPF Editor. - Use ISPF/PDF to allocate data sets and edit data sets using the ISPF Editor primary and line commands.

🚀 Excited to announce that I have earned the IBM Z Xplore - All Star Badge! This credential signifies a broad and deep understanding of IBM Z, showcasing my ability to think critically across various IBM Z skills. Achieving this badge involved earning the IBM Z Xplore Concepts and Advanced badges, and navigating system activities using tools like VS Code, Zowe, 3270 terminal, and LinuxONE environments. Key skills demonstrated include: - TSO (Time Sharing Option) - JCL (Job Control Language) - RACF (Resource Access Control Facility) - SDSF (System Display and Search Facility) - DFSMS (Data Facility Storage Management Subsystem) - SMP/E (System Modification Program/Extended) - Db2 (Database Management System) - Linux Additionally, I have developed expertise in: - 3270 Terminal Operations - Ansible Automation - Database Management - System Development - Node.js Programming - Security Protocols - System Operations - Go Programming - System Administration This achievement not only enhances my technical proficiency but also reinforces my problem-solving capabilities and understanding of enterprise-level infrastructure. A huge thank you to the IBM Z community and mentors for their support and guidance throughout this journey. I am eager to apply these skills to contribute to innovative projects and drive technological advancements in the field of enterprise computing.

I just finished the first course in Coursera's IBM #Mainframe specialization. IBM's z/OS is a very different environment than a desktop or server OS, and it's been a fun couple of weeks. Did you know that on a mainframe, applications see RAM, disk storage, and auxiliary flash as homogeneous? The OS makes no distinctions. A very interesting thought! Up next, COBOL!
