===== 1.5. Update or errata Management =====





Software packages in Red Hat products are subject to updates, referred to as errata that are released at regular intervals as well as asynchronously. Red Hat Satellite provides tools to inspect and filter errata, allowing for precise update management. This way, you can select relevant updates and propagate them through content views to selected content hosts.


Errata contain advisories that describe the changes introduced by the update. There are three types of advisories (in order of importance):


'''Security Advisory''' describes fixed security issues found in the package. The security impact of the issue can be Low, Moderate, Important, or Critical.


'''Bug Fix Advisory''' describes bug fixes for the package.


'''Product Enhancement Advisory''' describes enhancements and new features added to the package.


In Red Hat Satellite, there are two keywords that describe an erratum's relationship to the available content hosts:


'''Applicable:''' erratum applies to one or more content hosts, which means it updates packages present on the content host. Applicable errata are not yet accessible by the content host.


'''Installable: '''erratum applies to one or more content hosts and it has been made available to the content host. Installable errata are present in the content host’s life cycle environment and content view, but are not yet installed. This way, errata can be installed by users who have permissions to manage content hosts, but are not entitled for errata management at higher levels.


The procedure is to view the errata , inspect and apply .You can configure email notifications for Satellite users . Users can receive a summary of applicable and installable errata, notifications on content view promotion or after synchronizing a repository.
