3.7 Configuring an Oracle Linux 5 System to Use yum with ULN

If your Oracle Linux 5 system is registered with ULN, you can use yum instead of up2date to download and install packages. If you have installed a full update since Oracle Linux 5 Update 6 was released on January 20, 2010, your system should already be able to use yum with ULN.

To enable yum support:

  1. Install yum-rhn-plugin.

    # up2date --install yum-rhn-plugin
  2. If your organization uses a proxy server as an intermediary for Internet access, specify the enableProxy and httpProxy settings in /etc/sysconfig/rhn/up2date as shown in this example.


    If the proxy server requires authentication, additionally specify the enableProxyAuth, proxyUser, and proxyPassword settings:


    All yum users require read access to /etc/sysconfig/rhn/up2date. If this file must be world-readable, do not use a password that is the same as any user's login password, and especially not root's password.

With the plugin installed, you can immediately start to use yum instead of up2date.
