The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
        Oracle supports Spacewalk servers that are running on Oracle
        Linux 6 (x86_64) or Oracle Linux 7
        (x86_64). Oracle recommends that you update
        Oracle Linux with the latest packages that are available on the
        Oracle Linux yum server.
      
Do not register a Spacewalk server or client with ULN. You can register a Spacewalk server as a client of itself to receive updates.
        You should install Oracle Linux 6 or Oracle Linux 7 by using
        either the Minimal
        or Basic Server software set.
        If you select additional package groups during installation,
        remove the jta package before installing
        Spacewalk, as this package causes Spacewalk services to fail to
        start.
      
Install Spacewalk by using only the packages that are provided by Oracle from the Oracle Linux yum server at https://yum.oracle.com.
No third-party package repositories are required to install Spacewalk on Oracle Linux 6 or Oracle Linux 7. All of the required packages are available in the Spacewalk repositories on the Oracle Linux yum server.
