Installing Oracle RAC 10g
This section describes the steps required to install Oracle RAC 10 g , which involves installing CRS and
installing the Oracle Database 10
g 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
To prevent failures during the installation procedure, configure all cluster nodes with identical system clock
settings.
Synchronize your cluster 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 cluster nodes as an NTP server to synchronize the remaining nodes in the
cluster.
