local mirror (yum or ULN)?
With the help of this forum I was able to setup a local mirror server running OL7 and it was able to provide updates to OL7 and OL8 servers. Now that we have upgraded it to OL8 it seems things are not working like they used to and it was time to review how things were done and the notes I was pointed to by MOS were different. Like I needed to use dnf-config-manager and then reposync where I didn't have that setup before.
Now as I look at the guide they recommended in more detail https://docs.oracle.com/en/operating-systems/oracle-linux/software-management/sfw-mgmt-UseSoftwareDistributionMirrors.html#local-uln-mirror
