In a previous post I covered a few useful yum commands. One of these is repoquery, a tool for querying yum repositories in a similar way to using rpm queries. repoquery works directly against the Oracle Linux yum server.
Whereas the following works against yum.oracle.com:
$ sudo repoquery --list vim-minimal
When using, ULN you must use the --plugins flag for the repoquery command to return anything
$ sudo repoquery --plugins --list vim-minimal
