Installing Oracle 11g RAC
This section describes the steps required to install Oracle 11g RAC, which involves
installing CRS and installing the Oracle Database 11g software. Dell recommends
that you create a seed database to verify that the cluster works correctly before you
deploy it in a production environment.
Before You Begin
The following sections describe activities that you should complete before installing
Oracle 11g RAC.
Download the Enterprise Linux and Dell Automation Scripts
Before you install the Oracle RAC software on your system:
• Download the
Red Hat CD images from www.rhn.redhat.com . The Oracle
Enterprise Linux CD images can be downloaded from
www.oracle.com/linux .
• Locate your Oracle CD kit.
• Download the
Dell automation scripts that are appropriate for the solution
being installed from the Dell|Oracle Tested and Validated Configurations
website at
dell.com/oracle .
Configure the System Clock Settings for All Nodes
To prevent failures during the installation procedure, configure all the nodes with
identical system clock settings.
Synchronize your node system clock with a Network Time Protocol (NTP) server.
If you cannot access an NTP server, perform one of the following procedures:
• Ensure that the system clock on the Oracle Database software installation
node is set to a later time than the remaining nodes.
• Configure one of your nodes as an NTP server to synchronize the remaining
nodes in the cluster.
