Table 2.1. Stand-Alone Database and Embedded Database Satellite Hardware Requirements
The following hardware configuration is required for the Stand-Alone Database:
• Two processors
• 2 GB of memory
See
Section 2.3, “Database Requirements”
for instructions on estimating the tablespace of the
database and setting its environment variables.
Keep in mind, the frequency with which client systems connect to the Satellite is directly related to
load on the Apache Web server and the database. Reducing the default interval of four hours (or
240 minutes) as set in the
/etc/sysconfig/rhn/rhnsd
configuration file of the client systems
significantly increases the load on those components.
Additional hardware requirements include:
• The Stand-Alone Database must not run on the same server as the RHN Satellite Server.
• The package repository may be any large storage device easily and securely accessed by the
other components. The space requirements depend on the number of packages that will be stored.
Default Red Hat channels contain approximately 3 GB of packages each, and that size grows with
each synchronization; customers must also account for the space requirements of packages in their
own private channels. Whatever storage solution the customer chooses, its mount point may be
defined during the installation process.

Requirements”
