Enable update Oracle linux

This system is not registered with ULN / RHN

One of the features of WordPress is the ability to see search terms which are taking viewers to your blog. One of the all-time highest searches bringing traffic to my site is “This system is not registered with ULN”… and sure enough if I search for that phrase on Google my site is one of the top links, taking people to one of my Violin Memory array Installation Cookbooks.

So I guess it’s only fair that I give these passers by some sort of advice on what to do if you see this message…

1. Don’t Panic

Chances are you have built a new Linux system using Red Hat Enterprise Linux or its twin sister Oracle Linux. You are probably now trying to use yum to install software packages, but every time you do so you see something similar to this:

# yum install oracle-validated -y
Loaded plugins: rhnplugin, security
This system is not registered with ULN.
ULN support will be disabled.

--> Running transaction check
---> Package oracle-validated.x86_64 0:1.1.0-14.el5 set to be updated
...

Here’s an example of how to set it up for OL6:
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ol6.repo


#yum check update
