Installing Oracle 11g R2 Grid Infrastructure 29

Installing Oracle 11g R2 Grid

Infrastructure

This section gives you the installation information for Oracle 11g R2 grid

infrastructure for a cluster.

Before You Begin

Before you install the Oracle 11g R2 RAC software on your system:

• Ensure that you have already configured your operating system, network,

and storage based on the steps from the previous sections within this

document.

• Locate your Oracle 11g R2 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

daemon (ntpd) service using the commands in the following order:

1 service ntpd stop

2 chkconfig ntpd off

3 mv /etc/ntp.conf /etc/ntp.conf.orig

4 rm /var/run/ntpd.pid
