Change the Oracle Clusterware Configuration for an Instance

This example illustrates how to modify an instance to use TimesTen replication with Oracle Clusterware. Since TimesTen replication with Oracle Clusterware is not supported on Oracle Linux for Arm systems, do not run this example if you are using Oracle Linux for Arm.

After creating an instance, use the ttInstanceModify -crs option to change the TimesTen configuration to use Oracle Clusterware for TimesTen Replication and specify the full path to the Oracle Clusterware installation. As shown in the example, there is a prompt to confirm whether you want to configure TimesTen Replication with Oracle Clusterware and to enter or confirm the directory path to the installation. There must be a valid Oracle Clusterware installation in the specified directory. In this example, the current directory is timesten_home. User entries or defaults that are chosen are shown in bold.

This example provides the path to the Oracle Cluster installation as /u01/app/crs_releasedir/grid, where crs_releasedir is a variable for the CRS release (for example, if the CRS release is 19.1.0, you could substitute, 19.1.0, such that the path would be /u01/app/19.1.0/grid).

NOTE: By default, all of the nodes listed above will be added to the TimesTen
      Replication with Oracle Clusterware configuration. You can also
      specify your own list of nodes based on the list above.
