Global Repository for Mainframe developers
How to start with mainframe devops
Recently our team has been working closely on the processes of automating software development, testing and maintenance on mainframes. And we want to share the results with you. We hope they will help you to do DevOps on your mainframes.
Meet the GRMD
A Home for All Things Mainframe
The GRMD is a 100% open-source repository that includes useful, tested, and searchable mainframe solutions. It includes commands, scenarios, and templates to solve common mainframe problems and modernize the discipline.
We developed the repository to solve the biggest challenge that mainframe professionals encounter every day — finding ad hoc solutions to ad hoc mainframe problems.
Modernizing Mainframe
Ending the Ad Hoc Search for Solutions
Historically, mainframe has been a very siloed discipline. Everyone has created their own solutions, and kept their solutions to themselves.
The result: When you run into a problem you can’t solve, you have to perform a long, winding, ad hoc search for a solution.
- You will look through your own notes.
- You will ask your experienced colleagues.
- You will read tons of boring documentation.
- You will browse decades of complex forum posts.
- Ultimately, you will still have to make your own stopgap fix.
The whole process is slow, frustrating and ineffective.
And we built our repository so you never have to perform searches again.
