In this WebLogic Server domain topology, there is a WebLogic Administration server and a Coherence cluster. In the Coherence cluster is a WebLogic Server cluster. In the WebLogic Server cluster, one of the servers is storage-disabled (the WebLogic Server Coherence client tier) and two are storage-enabled (WebLogic Server Coherence server tier). In case of failover, one server can be used as backup for the other. There are no managed Coherence servers or clusters.
