4.5.2.1. Apply Errata Updates
Errata Alerts include a list of updated packages that are required to apply the Errata Update. To apply
Errata Updates to a system, the system must be entitled.
You can apply all applicable Errata Updates to a system by clicking on Systems => Systems in the
top and left navigation bars. Click on the name of an entitled system, and click the Errata tab of the
resulting System Details page. When the Relevant Errata list appears, click Select All then the Apply
Errata button on the bottom right-hand corner of the page.
In addition, Enterprise-level users can apply Errata Updates using two other methods:
To apply a specific Errata Update to one or more Enterprise-level systems, find the update within
•
the Errata lists or by searching. In the table, click on the number of systems affected, which will
take you to the Affected Systems tab of the Errata Details page. Then, individually select the
systems to be updated and click the Apply Errata.
To apply more than one Errata Update to one or more systems, select the systems from a Systems
•
list and click the Update button. Click the System Set Manager link in the left navigation bar, then
click the Systems tab. After ensuring the appropriate systems are selected, click the Errata tab, se-
lect the Errata Updates to apply, and click the Apply Errata button. You can select to apply the
Errata as soon as possible (the next time the Red Hat Network Daemon on the client systems con-
nect to RHN) or schedule a date and time for the Errata Updates to occur. Then click the Schedule
Updates button. You can follow the progress of the Errata Updates through the Pending Actions
list. Refer to Section 4.7 for more details.
Important
If you choose to apply Errata Updates automatically, the packages will be installed via the RHN
Daemon. You must have the RHN Daemon enabled on your systems. Refer to Chapter 5 for more
details.
The following rules apply to Errata Updates:
Each package is a member of one or more channels. If a selected system is not subscribed to a
•
channel containing the package, the package will not be installed on that system.
If a newer version of the package is already on the system, the package will not be installed on that
•
system.
If an older version of the package is installed, the package will be upgraded.
