Chapter 1. What is Red Hat Network?
1.3. Enterprise
In addition to the features offered in the RHN Demo and Basic subscription levels, the RHN Enterprise
subscription service allows you to manage your network of Red Hat Linux systems, users, and system
groups through its System Set Manager interface.
RHN Enterprise is based upon the concept of an organization. Each Enterprise-level Red Hat cus-
tomer is assigned a Red Hat Customer Number. A Red Hat Network organization can be established
for each Red Hat Customer Number. Each Red Hat Network organization contains users who have
administration privileges to system groups. An Organization Administrator has overall control over
each Red Hat Network organization with the ability to add and remove systems and users. When users
other than the Organization Administrator log into the Red Hat Network website, they see only the
systems they have permission to administer.
To create an account that can be used to entitle systems to RHN Enterprise, go to
https://rhn.redhat.com/ and click on the Create Account link under the Sign In fields. On the Sign
Up for Red Hat Network page, click Create a new corporate account. After creating a corporate
account, you may add users within your organization to it.
The Red Hat Network features available to you depend on the subscription level for each Red Hat
Linux system. With each Enterprise subscription, you receive the functionality provided to Demo and
Basic users, plus:
Package Profile Comparison — Compare the package set on a system with the package sets of
•
similar systems with one click.
Search Systems — Search through systems based on a number of criteria: packages, networking
•
information, even hardware asset tags.
System Grouping — Web servers, database servers, workstations and other workload-focused sys-
•
tems may be grouped so that each set can be administered in common ways.
Multiple Administrators — Administrators may be given rights to particular system groups, easing
•
the burden of system management over very large organizations.
System Set Manager — You may now apply actions to sets of systems instead of single systems.
•
Work with members of a predefined system group, or work with an ad-hoc collection of systems.
Install a single package to each, subscribe them all to a new channel, or apply all errata to them
with a single action.
Massive Scalability — Figuring out a list of outdated packages for a thousand systems would take
•
days for a dedicated sysadmin. Red Hat Network Enterprise Service can do it for you in seconds.
1.4. Errata Notifications and Scheduled Package Installations
You can configure the Red Hat Network to send you email notifications of new and updated software
packages as soon as the packages are available through RHN. You can also schedule package installs
or package updates. The benefits include:
Reduced time and effort required by system administrators to stay on top of the Red Hat Errata list
•
Minimized security vulnerabilities in your network by providing the patches as soon as Red Hat
•
releases them
Filtered list of package updates (packages not relevant to your network are not included)
•
Reliable method of managing multiple systems with similar configurations
