Both yum repositories and ULN channels are directories of packages, along with their relevant metadata, which are accessed by clients using the dnf or yum command line tools. However, the packages follow a different naming scheme:

• Yum repositories are named based on the Oracle Linux release and software stream. For example, ol10_appstream or ol10_baseos_latest provide the minimum required packages for Oracle Linux 10.

• ULN channels include the platform architecture in their name, for example the ol10_x86_64_appstream and ol10_aarch64_baseos_latest channels provide the minimum required packages for Oracle Linux 10 on systems with x86_64 architectures. For aarch64 systems, the ol10_aarch64_appstream and ol10_aarch64_baseos_latest channels provide the minimum required packages for Oracle Linux 10.
