Configuring Connections to Oracle RAC Sources for High Availability
Configuring Connections to Oracle RAC Sources for High Availability
For Oracle RAC sources that have multiple database and ASM instances, configure Data Replication support of failover to provide high availability of replicated data.
If you enable failover and a particular instance becomes unavailable for a Data Replication replication component, such as the Extractor or Data Replication Console, the replication component can connect to another instance.
For Data Replication to support failover of an Oracle RAC source, either use custom connection strings that provide connection information for all of the cluster instances or use a virtual IP address that is routed to an active cluster node to connect to the Oracle RAC.
