We want to use the "atop" program, which happens to be contained in the "ol7_x86_64_developer_EPEL" repository, which corresponds to the "EPEL Packages for creating test and development environments for Oracle Linux 7" channel in ULN. On a CentOS system the atop program is in the EPEL repository, and the EPEL repository can be configured by issuing the "yum install epel.release".
Under Oracle Linux ULN, many of the software channels do have a "xxx.release" yum package, which when installed will configure the repository ... once you know the ULN channel name to repository package name mapping.
In the case of the "ol7_x86_64_developer_EPEL" repo, there does not seem to be a "xxx.release" package.
It is also interesting to note, that the "atop" program is contained in the ol7_x86_64_developer_EPEL repository and NOT the normal oracle-epel-release-el7 repository.
Here are all the yum packages that contain the word "release"
# yum list "*release*"
Loaded plugins: rhnplugin, ulninfo
This system is receiving updates from ULN.

Which one, if any, would configure the ol7_x86_64_developer_EPEL repository.
Thank you.
