Oracle Linux Repositories
When you create an instance using the Oracle Linux platform image, certain yum channels, or repositories, are automatically enabled by default on the instance. These enabled repositories provide access to important security updates and bug fixes for the instance.
If you choose to register the instance with OS Management Hub at a later time, you can specify these enabled repositories (software sources) in your OS Management Hub registration profile. For more information about registering an instance with OS Management Hub, see Registering an OCI Instance.
