ECDA 15.0 and earlier supports replication into an Oracle instance, even if that instance is a node in a Real Application Cluster (RAC) system. However, if the configured node fails, ECDA 15.0 and earlier does not support automatically failing over to another node in the RAC system.
As of ECDA 15.0 ESD #1, automatic failover
when replicating into a RAC system
is supported.
Workaround: When the node that the ECDA service is connected to fails, reconfigure the ECDA service to use a different node in the RAC system.
