Beatriz,
I wanted to update you on the progress of our MQ V9 certification. We have completed the certification testing on CA Gen z/OS, and are now finishing up the distributed CA Gen platforms (Windows, Unix, etc.).
We won't announce the formal certification until all components are complete. Since there are several versions each of Unix and Windows, it takes a bit longer to run through all the testing there.
We have not seen any issues so far with MQ V9.
I'll update you again once we announce the full certification. In the meantime, rest assured you are supported on the current version of MQ.
Regards,
Rob Thompson
Product Owner, CA Gen
