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.

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.

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 Red Hat Enterprise

Linux AS 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

RHN as a separate role to certain customers, gives them the ability to create and manage their own

custom channels.

Channels can be further broken down by their relevance to your systems. Two such lists emerge:

Relevant and All.

4.6.1.1. Relevant Channels

As shown in Figure 4-6, the Relevant Channels page is shown by default when you click Channels

in the left navigation bar. It displays a list of channels now associated with your systems. Links within

this list go to different tabs of the Channel Details page. Clicking on a channel name takes you to

the Details tab. Clicking on the packages number takes you to the Packages tab. And clicking on the

systems number takes you to the Subscribed Systems tab. Refer to Section 4.6.1.3 Channel Details

for details.
