1.4. 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 4.0.5 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).

nel management interface.
•
RPM Repository — package repository for Red Hat RPM packages and custom RPM
