Installation guide

Introduction
This document provides recommendations for running Oracle 10g R2 standalone and RAC databases on Red
Hat Enterprise Linux (RHEL).
The recommendations presented in this document are targeted to the following hardware platforms:
● 64-bit physical system (x86_64) with SAN attached storage for Oracle
● VMware virtual machine (x86_64) with virtualized disks for Oracle
We will present generic tuning recommendations for systems with 1, 4, 8, 16, 32 and 64GB of RAM. These
generic recommendations may require adjustments depending on the Oracle database characteristics and work-
load.
We assume that physical systems have at least two NICs and two HBAs to provide redundant network and SAN
connections.
We present an example of Linux native multipath configuration for EMC CLARiiON and SYMMETRIX stor-
age arrays.
If the database servers need to be installed on multiple target hosts, it is recommended to package the Oracle
software via RPM using RPM Packaging Guide for Oracle 10g on Red Hat Enterprise Linux 5. Then the Oracle
installation can be integrated with software management tools like Red Hat Network Satellite or yum and can be
unattended.
64-bit Architecture
This is the architecture that should be used whenever possible. The 32-bit platform is also supported but for the
large databases, the x86_64 architecture is strongly recommended. For supported system configurations and
limits for Red Hat Enterprise Linux releases, see http://www.redhat.com/rhel/details/limits/.
If you can go with a x86-64 platform ensure that all drivers you need are supported on x86-64 (e.g. proprietary
multipath drivers such as EMC PowerPath, etc.) Furthermore, ensure that all the required applications are sup-
ported on x86-64.
