Currently Oracle GoldenGate supports 6 topologies to enable data replication and integration across different environments, they are as below:
◾ Undirectional Replication
◾ Bidirectional (Active - Active) Replication
◾ Peer-to-Peer (Multi-Master) Replication
◾ Broadcast (Hub-and-Spoke) Replication
◾ Consolidation (N-to-1) Replication
◾ Cascading Replication
