• 2 GB of memory

See Section 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.

If you are installing RHN Satellite Server with Embedded Database, skip to Section 4,

“Additional Requirements”.

3. Database Requirements

This section applies only to RHN Satellite Server with Stand-Alone Database as the

requirements for the Embedded Database are included in the Satellite machine's hardware

requirements. Red Hat supports RHN Satellite Server 5.0.0 installations in conjunction with

Oracle 9i R2. The Stand-Alone Database must not run on the same server as the RHN Satellite

Server.

A single 6 GB tablespace is recommended as more than sufficient for most installations. It is

possible for many customers to function with a smaller tablespace. An experienced Oracle

database administrator (DBA) will be necessary to assess sizing issues. The following formula

should be used to determine the required size of your database:

• 192 KB per client system

• 64 MB per channel

For instance, an RHN Satellite Server containing 10 channels serving 10,000 systems would

require 1.92 GB for its clients and 640 MB for its channels. If custom channels are to be

established for testing and staging of packages, they must be included in this formula.

Keep in mind, the database storage needs may grow rapidly, depending upon the variance of
