and

radio buttons and then clicking the

button alters your

•
Receive Notifications of Updates/Errata
— This setting keeps you abreast of all advisories per-
taining to your systems. Anytime an update is produced and released for a system under your
supervision, a notification is sent via email.
•
Include system in Daily Summary — This setting includes the selected systems in a daily sum-
mary of system events. (By default, all Management and Provisioning systems are included in the
summary.) These are actions affecting packages, such as scheduled Errata Updates, and system re-
boots or failures to check in. In addition to including the systems here, you must choose to receive
email notifications in the Your Preferences page of the Your RHN category. Refer to Section 6.3.2
Your Preferences for instructions. Note that RHN will send these summaries only to verified email
addresses.
•
Automatic application of relevant Errata
— This setting allows you have all Errata Updates au-
tomatically applied to systems. This means packages associated with Errata will be updated without
any user intervention. Customers should note that Red Hat does not recommend the use of the auto-
update feature for production systems because conflicts between packages and environments can
cause system failures.
6.4.5. System Entitlements
To use all of the features of RHN, your systems must be entitled — subscribed to an RHN service
level. Use the System Entitlements page to configure which systems are entitled to which service
offerings. There are three primary types of entitlements:
•
Update
— should be used to manage a single Red Hat Enterprise Linux system. It includes Errata
Alerts, Scheduled Errata Updates, Package Installation, and the Red Hat Update Agent .
•
Management
— should be used to manage multiple systems with multiple system administrators.
In addition to the features of the Update offering, it includes system group management, user man-
agement, and the
System Set Manager
interface to quickly perform actions on multiple systems.
•
Provisioning — offers the highest level of functionality. It should be used to provision multiple sys-
tems that will need to be re-installed and reconfigured regularly. The Provisioning offering provides
tools for kickstarting machines, managing their configuration files, conducting snapshot rollbacks,
and inputting searchable custom system information, as well as all of the functionality included in
the Management service level.
The
System Entitlements
page allows you to view and promote the entitlements for your registered
systems. Only increases in entitlement levels are allowed. Systems cannot be re-entitled to a lower
entitlement level. For instance, a system entitled to the Update service level can be promoted to the
Management level, but this action cannot be reversed.
To change an individual entitlement, select the entitlement from the system’s pulldown menu and
click the
Update Entitlements
button on the bottom right-hand corner of the page. Click the name of
a system to see details about it. If no drop-down menu exists for your Update-level system, you may
need to purchase a Management entitlement. Do this through the Buy Now link at the left of the page.
