If a newer version of the package is already on the system, the package will not be installed on that

4.5.2.2. Errata Details
If you click on the Advisory of an Errata Alert in the Relevant or All pages, its Errata Details page
appears. This page is further divided into three tabs:
•
The Details tab provides the Errata Report issued by Red Hat. It describes the problem and solution
and lists the channels it affects. Clicking on a channel name displays the
Packages
tab of the
Channel Details
page. Refer to Section 4.6.1.3 Channel Details for more information.
•
The Packages tab provides links to each of the updated RPMs broken down by channel. Clicking
on the name of a package displays its
Package Details
page. Refer to Section 4.6.5.3 Package
Details for more information.
•
The
Affected Systems
tab shows a list of systems affected by the Errata Alert. Clicking on the
name of a system takes you to its System Details page. Refer to Section 4.4.1.5 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.
4.6. 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.
