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.
6.5.3. 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.
6.6. Channels
If you click the
Channels
tab on the top navigation bar, the
Channels
category and links appear. The
pages in the
Channels
category enable you to view and manage the channels and packages associated
with your systems. In addition, you can obtain ISO images here.
6.6.1. Software Channels
The
Software Channels
page is the first to appear in the
Channels
category. A software channel is a
list of Red Hat Enterprise Linux packages grouped by use. Channels are used to choose packages to
be installed on a system.
There are two types of software channels:
base channels
and
child channels
. A base channel consists
of a list of packages based on a specific architecture and Red Hat Enterprise Linux release. For ex-
ample, all the packages in Red Hat Enterprise Linux 2.1 for the x86 architecture is a base channel.
The list of packages in Red Hat Enterprise Linux 2.1 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 Enterprise Linux 2.1 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 Enterprise Linux release and system architecture selected.
In the case of public free channels, the action will succeed. In the case of 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
.
6.6.1.1. Relevant Channels
As shown in Figure 6-6, the
Relevant Channels
page is shown by default when you click
Software
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
Software Channel Details
page. Clicking on a channel
