Page: 9 / 84

Red Hat Network organization must have at least one Organization Administrator.
• certificate authority — A Channel Administrator is a user role with full access to channel
management capabilities. Users with this role are capable of creating channels, assigning
packages to channels, cloning channels, and deleting channels. This role can be assigned by
an Organization Administrator through the Users tab of the RHN website.
• Red Hat Update Agent — The Red Hat Update Agent is the Red Hat Network client
application that allows users to retrieve and install new or updated packages for the client
system on which the application is run. For Red Hat Enterprise Linux 5 users, use the
yum
command; for Red Hat Enterprise Linux 4 and lower, use the
up2date
command.
•
Traceback — A traceback is a detailed description of "what went wrong" that is useful for
troubleshooting the RHN Satellite Server. Tracebacks are automatically generated when a
critical error occurs and are mailed to the individual(s) designated in the RHN Satellite
Server's configuration file.
For more detailed explanations of these terms and others, refer to the Red Hat Network
Reference Guide.
4. How it Works
RHN Satellite Server consists of the following components:
• Database — for the Stand-Alone Database, this may be the organization's existing database
or, preferably, a separate machine. RHN Satellite Server supports Oracle 9i R2. For the
Embedded Database, the database comes bundled with RHN Satellite Server and is installed
on the same machine as the Satellite during the installation process.
•
RHN Satellite Server — core "business logic" and entry point for Red Hat Update Agent
running on client systems. The RHN Satellite Server also includes an Apache HTTP Server
(serving XML-RPC requests).
• RHN Satellite Server Web interface — advanced system, system group, user, and channel
management interface.
• RPM Repository — package repository for Red Hat RPM packages and custom RPM
packages identified by the organization.
• Management Tools:
• Database and file system synchronization tools
• RPM importing tools
• Channel maintenance tools (Web-based)
