updates here. (See Section 4.5.2.1 Apply Errata Updates.) Clicking on the name of a system takes
you to its System Details page. Refer to Section 4.4.2.6 System Details for more information.
To help users determine whether an update has been scheduled, a Status column exists within the
affected systems table. Possible values are: None, Pending, Picked Up, Completed, and Failed. This
column identifies only the latest action related to an Errata. For instance, if an action fails and you
reschedule it, this column will show the status of the Errata as Pending only (with no mention of
the previous failure). Clicking a status other than None takes you to the Action Details page. This
column corresponds to one on the Errata tab of the System Details page.

4.5.3. Advanced Search

The Advanced Search page allows you to search through Errata according to specific criteria, such
as summary, advisory, and package name. Type your keyword, select the criterion to search by, and
click the Search button. The results appear at the bottom of the page.

4.5.4. Manage Errata

The Manage Errata page enables RHN Enterprise customers who have their own private channel to
issue Errata Alerts for their packages. Refer to the RHN Channel Management Guide for instructions
on obtaining and using this ability.

4.6. Software

If you click the Software tab on the top navigation bar, the Software category and links appear. The
pages in the Software category enable you to view and manage the channels and packages associated
with your systems. In addition, you can obtain ISO images here.

4.6.1. Channels

The Channels page is the first to appear in the Software category. A channel is a list of Red Hat
Linux packages grouped by use. Channels are used to choose packages to be installed on a system.
There are two types of channels: base channels and child channels. A base channel consists of a list of
packages based on a specific architecture and Red Hat Linux release. For example, all the packages in
Red Hat Linux 7.1 for the x86 architecture is a base channel. The list of packages in Red Hat Linux 7.1
for the Itanium architecture is a different base channel. A child channel is a channel associated with
a base channel but contains extra packages. For example, an organization can create a child channel
associated with Red Hat Linux 7.1 for the x86 architecture that contains extra packages needed only
for the organization, such as a custom engineering application.
A system must be subscribed to one base channel only. This base channel is assigned automatically
during registration based upon the Red Hat Linux release and system architecture selected. In the case
of public free channels (RHL 6.2, 7.x, 8.0), the action will succeed. In the case of Advanced Server
and other paid base channels, this action will fail if an associated entitlement doesn't exist.
A system can be subscribed to multiple child channels of its base channel. Only packages included in
a system's subscribed channels can be installed or updated on that system. Some customers, such as
those using RHN Satellite and Proxy, have channel management authority. This authority, granted by
