The document discusses extending DevOps practices to include mainframe systems, highlighting challenges like accessibility of mainframe data, lack of expertise, and manual processes. It presents a demonstration of creating a basic DevOps pipeline using Jenkins and shell scripts to automate build and test processes for COBOL code changes. The goal is to improve collaboration, application understanding, and operational efficiency while leveraging automation for more effective development cycles.

All data is on the Mainframe – test scripts, source code, build scripts – inaccessible to DevOps tools and frameworks typically used on open systems 2. Lack of Mainframe expertise – green screen interfaces, OS essentials, lack of documentation etc. 3. No self-service but tickets, manual steps and wait times

- 17. Copyright © 2018 CA. All rights reserved. Recap • We created a fully functional, basic DevOps pipeline that extends from distributed to the Mainframe systems using readily available tools: • Jenkins CI • Shell scripts • Gulp framework • CA Brightside Community Edition • We are able to automate all the build and test steps required after each COBOL code change. • All the scripts logic and data remains on the distributed system for easy modification and improvement after each iteration. • z/OS platform is utilized as “just another platform” through Bright commands and command groups. • We now have a solid foundation for automation of more complex scenarios and trigger events.
