DPA is not supported for Db2 11.5. It is released by IBM more than a year ago. Db2 10.5 is already out of support. Db2 11.1 will be out of support in 1.5 years. Please work on supporting Db2 11.5
FYI, @ramkaza I was just looking at the Admin Guide for the new 2020.4 RC. It now mentions monitoring for Db2 11.5 (and 11.1) is supported.
Whether there's any attempt to use new Db2 monitoring features, I don't know.
Db2 11.5 is now supported in the DPA 2021.1 release made generally available January 20, 2021
