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

• 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

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
