Hello,
MQ is officially supported on RHEL, Ubuntu and Suse. So if you want to use something that is officially supported go for Ubuntu which can be installed for free.
Personally I use Centos 7.6 o ...
I would like to test some RDQM on my private side.
But RHEL 7* requires subscription.
But CentOS is "almost" a clone, but for sure IBM RDQM will not work on CentOS?
