We are excited to announce that we released CA IMS database management solutions for IMS for z/OS r20 (link to our documentation here).We worked hard to announce IBM IMS DB version 15 support from day 1 and we made it. We know you would like to take advantage of our features that were delivered before and we heard you when you said that you would like us to simplify the install/post-install process. Well, we made it too. We hope that you will find simplified process more convenient. You can read about it here.
If you ask yourself what we support, check current support matrix which can be found here.
