Overview
This document applies to Oracle Database 11g R2 running on Red Hat
Enterprise Linux 5.x AS x86_64 or Oracle Enterprise Linux 5.x AS x86_64.
Before You Begin
Hardware Requirements
• Oracle requires 1.5 gigabytes (GB) of physical memory.
• Swap space must be equal to the amount of RAM allocated to the system.
• Oracle's temporary space (/tmp) must be at least 1 GB in size.
• A monitor that supports resolution of 1024 x 768 to correctly display the
Oracle Universal Installer (OUI).
• For Dell-supported hardware configurations, see the Software Deliverable
List (SDL) for each Dell Validated Component at
dell.com/oracle .
Table 1-1 describes the disk space required for an Oracle installation.
Network Requirements
• It is recommended that you ensure each node contains at least three
network interface cards (NICs). One NIC for public network and two
NICs for private network to ensure high availability of the Oracle Real
Application Clusters (RAC).
• Public and private interface names must be the same on all nodes. For
example, if
eth0 is used as the public interface on node one, all other nodes
require
eth0 as the public interface.
