Installing Oracle 11g R2 Database RAC 7
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:
1 service ntpd stop
2 chkconfig ntpd off
3 mv /etc/ntp.conf /etc/ntp.conf.orig
4 rm /var/run/ntpd.pid
