I installed the spacewalk 2.7 client software (from the Spacewalk project, not from Oracle) on a ULN6 and ULN7 test machine using the instructions at https://github.com/spacewalkproject/spacewalk/wiki/RegisteringClients.

This should work, but ULN is the name of our update service, not our distribution so this was a very confusing email for me. :) FYI, ULN is the equivalent of RHN so for future reference, I’d suggest referring to Oracle Linux or OL instead of ULN. :)

Also, installing the Spacewalk 2.7 client from the Spacewalk project is not recommended. We released our build of Spacewalk 2.7 a couple of days ago, so I suggest syncing and installing our Spacewalk client instead.

If your production servers are registered to ULN than those messages are unsurprising, because replacing the default client means that ULN-CA-CERT was removed, but the ULN configuration expected it. If you never register your clients with ULN, you would not see this message.

Note that the default client on Oracle Linux 6 Update 9 and Oracle Linux 7 Update 3 (or higher) supports registration direct to either ULN or Spacewalk out of the box. There is no need to install the Spacewalk client for registration, though we do recommend installing it anyway for additional functionality like rhncfg or osad.

You will not get support for the Spacewalk components, because those are not provided by Oracle. You won't invalidate your entire support though. Again, this is why I recommend using our build of Spacewalk and our client packages: you get support for Spacewalk included in your Oracle Linux support subscription.

It’s a side-effect of switching from ULN to Spacewalk and if your clients are working after a forced re-registration, I wouldn’t worry too much about it (because it shouldn’t reoccur after the registration anyway).
