Database Requirements - Red Hat NETWORK SATELLITE 5.1.1 Installation Manual

Database Requirements

2.3. 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 the
following factors:
• The number of public Red Hat packages imported (typical: 5000)
• The number of private packages to be managed (typical: 500)
• The number of systems to be managed (typical: 1000)
• The number of packages installed on the average system (typical: 500)
Although you should be generous in your database sizing estimates, you must consider that size
affects the time to conduct backups and adds load to other system resources. If the database is
shared, its hardware and spacing are entirely dependent on what else is using it.
Additionally, block sizes must be a minimum of 8 KB for RHN Satellite Server to install properly.
The Oracle database should have a user assigned to RHN Satellite Server with full DDL and DML
access to that user's default tablespace. The user needs standard connection information for the
database at the time of installation.
The precise access levels required by the Oracle user are as follows:
• ALTER SESSION
• CREATE SEQUENCE
• CREATE SYNONYM
• CREATE TABLE
• CREATE VIEW
• CREATE PROCEDURE
• CREATE TRIGGER
