Following the first reboot after installing Oracle Linux 6, you are
prompted to register your system with ULN. If you did not
configure your network during the installation, the
registration process to ULN cannot succeed. To register your
system, log in as the root
user, configure
the system's network manually, and run the
uln_register command.
