This can beany directory specifiable at backup time.Table 2-1. Stand-Alone Database and Embedded Database Satellite Hardware RequirementsThe following hardware configuration is required for the Stand-Alone Database:• Two processors• 2 GB of memorySee Section 2.3 Database Requirements for instructions on estimating the tablespace of the databaseand setting its environment variables.Keep in mind, the frequency in which client systems connect to the Satellite is directly related to loadon the Apache HTTP Server and the database. If you do reduce the default interval of four hours (or240 minutes), as set in the /etc/sysconfig/rhn/rhnsd configuration file of the client systems,you will increase the load on those components significantly.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 othercomponents. The space requirements depend on the number of packages that will be stored. DefaultRed Hat channels contain approximately 3 GB of packages each, and that size grows with eachsynchronization; customers must also account for the space requirements of packages in their ownprivate channels. Whatever storage solution the customer chooses, its mount point may be definedduring the installation process.If you are installing RHN Satellite Server with Embedded Database, skip to Section 2.4 AdditionalRequirements.2.3. Database RequirementsThis section applies only to RHN Satellite Server with Stand-Alone Database as the requirementsfor the Embedded Database are included in the Satellite machine’s hardware requirements. Red Hatsupports RHN Satellite Server 3.7 installations in conjunction with Oracle 9i R2. The Stand-AloneDatabase 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 possiblefor many customers to function with a smaller tablespace. An experienced Oracle database admin-
