Installing Oracle 11g R2 Database
RAC
This section describes the steps required to install Oracle 11g R2 Real Application
Clusters (RAC), which involves installing Oracle Grid Infrastructure for a cluster
and the Oracle Database 11g R2 software. It is recommended that you create a
seed database to verify that the cluster works correctly before you deploy it in a
production environment.
Before You Begin
Setting Up the Operating System, Network, and Storage
Before you install the Oracle RAC software on your system:
• Ensure that you have already configured your operating system, network, and
storage based on the steps contained in the documents listed in "Required
Documentation for Deploying the Dell|Oracle 11g R2 Database" on page 5.
• Locate your Oracle media kit.
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 the
Cluster Time Synchronization Service (CTSS) which is built in Oracle 11g R2. To
enable CTSS, disable the operating system network time protocol (OS NTP)
service using the following commands in order:
1 service ntpd stop
2 chkconfig ntpd off
3 mv /etc/ntp.conf /etc/ntp.conf.orig
4 rm /var/run/ntpd.pid
