Yes – this sounds crazy. Let me break it down.
- zPDT is a product from IBM that allows me to run system 390 application on my laptop. I am running z/OS 2.4, and MQ 9.1.3. For normal editing and running MQ – it feels as fast as when I had my own real hardware at IBM.
- z/OS 2.4 can run docker images in a special z/OS address space called zCX.
- I can run MQ distributed in docker.
Stringing these together I can run MQ distributed in a docker environment. The docked environment runs on z/OS. The z/OS runs runs on my laptop! To learn more about running this scenario on real z/OS hardware…
- Matt Lemming has a blog post called Use cases for MQ in z/OS Container Extensions.
- Tony Sharkey has written a document (MQ for z/OS Performance Report -Use cases with z/OS Container Extensions) about his measurements and the costs of running the scenarios that Matt describes.
20 years ago, someone was enthusiastically telling me how you could partition distributed servers using a product called VMWare. They kept saying how good it was, and asking why wasn’t I excited about it. I said that when I joined IBM – 20 years before the discussion (so 40 years ago), the development platform was multiple VS1 (an early MVS) running on VM/360. Someone had VM/360 running under VM/360 with VS1 running on that! Now that was impressive!
Now if only I could get z/OS to run in docker….
One thought on “Should I run MQ for Linux, on z/OS on my Linux?”
