12 Installing Oracle 11g R1 Database RAC
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.
