Errata

Red Hat releases Errata Alerts in three categories: Security Alerts, Bug Fix Alerts, and Enhancement Alerts. Each Errata Alert is comprised of a summary of the problem and the solution, including the RPM packages required to fix the problem. The Errata category allows you to view all released Errata Alerts, to view only Errata Alerts applicable to your systems, to search Errata Alerts, and to apply Errata Updates to one or more of your systems.

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 use one of these methods to apply Errata Updates:

  1. To apply all applicable Errata Updates to a system, click on Systems => System List on the left navigation bar. Click on the name of an entitled system, and click the Update This System button on the Details tabbed page. This action will apply all available Errata Updates on the system. To view a list of the Errata, click the Errata tab on the System Details page for the system.

  2. To apply a specific Errata Update to one or more systems, click on Errata on the left navigation bar and use the All Errata, Applicable Errata, or Errata Search page to find the Errata Update that you want to apply. From the Errata List, click on the Synopsis for the Errata Alert to display a summary of it. Click on the Systems Affected tab, and select the systems that you want to apply this update to. Click Update Selected Systems to apply the Errata Update to all selected systems, or click Update All Affected Entitled Systems to apply the update to all the affected systems listed.

  3. To apply more than one Errata Update to one or more systems, select the systems from the Systems => System List page. Click the System Set Manager link in the System Set Manager. Go to the System List tab to make sure these are the systems the ones that you want to apply the Errata to. Go to the Errata Updates tab, select the Errata Updates to apply, and click Apply Selected Errata. You can select to apply the Errata as soon as possible (the next time the Red Hat Network Daemon on the client systems connect to RHN) or schedule a date and time for the Errata Updates to occur. If you schedule the updates, the next time the Red Hat Network Daemon on the client systems connect to RHN after the selected date and time, the updates will be applied. Click Schedule Errata Update(s). You can follow the progress of the Errata Updates from the Scheduled Actions list.

ImportantImportant
 

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 7 for more details.

The following rules apply to Errata Updates:

  1. Each package is a member of one or more channels. If a selected system is not subscribed to the channel that the selected package is a member of, the package will not be installed on that system.

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

  3. If an older version of the package is installed, the package will be upgraded.

The packages will be updated by the RHN Daemon. You must have the RHN Daemon enabled on your systems. Refer to Chapter 7 for more details.

Errata Details

If you click on the synopsis of an Errata Alert, the Errata Details page for the Errata Alert will appear. This page is further divided into two tabbed pages: Details and Systems Affected.

The Details page provides the Errata Report issued by Red Hat. It describes what channels the Errata Alert affects, its problem and solution, MD5 verification for each of the packages, and the packages required for the Errata Update. Clicking on the RPM package name displays the Package Details page for the package. Refer to the Section called Package Details for more information.

The Systems Affected page shows a list of systems affected by the Errata Alert.
