Learn how to use modern DevOps tools to accelerate z Systems innovation At the heart of DevOps is making sure you have everything properly versioned, and many distributed teams have moved to using Git for this purpose. It’s such an easy software configuration manager (SCM) that people are using it everywhere and for everything – from version management to simple task management. Meanwhile, your z/OS code is sitting in an old SCM that new developers don’t know and don’t want to use. If you’re using Git for the rest of your development, why not use it for z Systems as well?

What is Git?
• Open Source source code management
capability built to manage Linux development
• Distributed Source Code Management
• Full copy of the repository locally for
each user their own private copy on their
own machine
• Uses a commit ID instead of a version
• SHA-1 hash based on the code,
what came before it, who made the
commit, when they made it, and
other metadata
• Forking the repository is normal

More on Git
• More info https://en.wikipedia.org/wiki/Git
• Git is available via https://git-scm.com
• Git for z/OS is provided by Rocket Software
• http://www.rocketsoftware.com/zos-open-source/tools
• Part of ported tools
• Provides the ability to run Git on z/OS
• Writes files to zFS
• Supports tagging files for EBDCIC, ASCII, UTF-8
• Adding a tag file to Git repository to indicate which files should be in which code page
• Configuration to say what code page should be used for repo

Jenkins
• Jenkins Slave already runs on z/OS
• Allows running tasks on z/OS
• With Rocket Git port can use existing Git plugins to pull code to z/OS for build

User Steps using ISPF
• Load files using Git pull
• Loads files to zFS
• Edit the files with standard ISPF editors
• Compile out of zFS or copy to PDSE as first build
step
• Commit back to Git when successful compile or
wanting to save state
• Push to central Git with successful test

User Steps using IDz
• Git pull using eclipse git plugin
• All IDz local project function available
• Push file to z/OS to do JCL build
• Commit to Git when wanting to save state
• Push to central Git when ready to share with others
