Installation of Oracle TimesTen and Clusterware

The installation and configuration tasks for both Oracle Clusterware and TimesTen are distinct and different.
This section describes how to install Oracle Clusterware and TimesTen.

Install Oracle Clusterware 11.1.0.7 on the cluster nodes

1.	Configure a Time Synchronization Mechanism	Active Standby Pairs managed by Oracle Clusterware should be supported by a clock synchronization protocol such as NTP. The Active Standby Pair clock skew on all nodes in the replication scheme should be within 250 milli-seconds for the cluster to be effective.
2.	Install Oracle Clusterware 11.1.0.6	Install Oracle Clusterware according to the instructions in the installation guide for the platform you are using.
3.	Verify all of the steps	Make sure that the Cluster Verify Utility is used to confirm that all nodes are properly configured for Oracle Clusterware during the pre and post installation steps. If Oracle Clusterware is not installed and configured correctly, then the TimesTen ttCWAdmin -create utility will not work correctly. If a time synchronization mechanism such as NTP is not installed and configured correctly, the TimesTen Replication will be disabled if the clock skew is above 250ms. Note Oracle Clusterware starts automatically after a successful installation.
4.	Upgrade to 11.1.0.7 patch	Apply the patch to your working Clusterware 11.1.0.6 installation and re-run the Cluster Verify Utility.

Install TimesTen 11.2.1 on the cluster nodes

1.	Install TimesTen on each node	Use the TimesTen installer to install TimesTen on each node where Oracle Clusterware was installed
2.	Use same config on each node	Install TimesTen as the same O/S user and in the same location on each node. Although you do not need to install TimesTen as the same O/S as Oracle Clusterware it will simplify the administration.
3.	Add clusterware specific parameters	When Timesten is to be used with Oracle Clusterware , the following Oracle Clusterware specific parameters must to be added either as part of the install or via ttModinstall: TCP Port (the port used by the TimesTen Cluster Agent) crsHome (the absolute path where Oracle Clusterware was installed) hosts (the list of hosts to be managed by Oracle Clusterware) Note TimesTen starts automatically after a successful installation.
