Important z/VSE 6.2 APARs/PTFs

z/VM Continuous Delivery News

z/VM Development maintains a z/VM Continuous Delivery News web page that describes the various enhancements for z/VM, both the ones in progress and the ones they have shipped. This essentially replaced most of what was done via announce letters in the past. You will find some items that they are just starting to consider as candidates as well as those in various phases of engagement with Sponsor Users. It changes multiple times per quarter so if it interests you, consider being on the notification list by clicking the "Notify me" link on the left hand navigation bar.

z/VM MONWRITE Data and Migrations

The z/VM article MONWRITE Data and Migrations describes what to collect in support of upgrades. But it is a good idea to collect such data weekly or so, and just archive it. You never know when it might come in handy.

50 Years of z/VSE - Voices from the IBM Development Team in Böblingen

In 2015 the VSE development team in the German IBM Lab celebrated 50 years of z/VSE operating system, originating back into the 60’s and the birth of the mainframe computers. Today, the OS is still running in data centers of a significant number of large companies around the world.

On reader request I am republishing the video 50 Years of z/VSE - Voices from the IBM Development Team in Boeblingen in the Library of the z/VSE Topic Group within the IBM Z and LinuxONE Community on IBM Community. Enjoy watching the video from the development team in Böblingen.
