The copy of Liberty that comes with z/OS is intended (read supported) for use with IBM products like z/OSMF. Your z/OS license allows you to use it for "non production purposes". There's a whole paragraph in the terms and conditions that tries to define what that means.
There's a blog post here that tries to explain it all: https://community.ibm.com/community/user/wasdevops/blogs/david-follis/2021/04/14/can-i-run-open-liberty-on-zos?CommunityKey=2878fdb3-1d66-40b6-b9ed-0cfff8979b7d David Follis IBM WebSphere z/OS ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
