This screen is displayed only if you included Coherence in the WebLogic Server installation. It lists the Coherence cluster that is automatically added to the domain.
When including a Coherence cluster in a domain:
All Managed Servers and clusters that you configure in the domain during future Configuration Wizard sessions are automatically added to the Coherence cluster.
Servers and clusters that already exist in the domain before you add a Coherence cluster to the domain are not automatically assigned to the Coherence cluster. If desired, you can manually assign them to the Coherence cluster via a WLST script or the Administration Console.
When creating a domain via the Configuration Wizard, if the domain contains only an Administration Server and no Managed Servers, the Administration Server is automatically assigned to the Coherence cluster. If, however, at least one Managed Server is added to the domain during domain creation, the Administration Server is not assigned to the Coherence cluster.
If there are multiple Coherence clusters in the domain (for example, you added a second Coherence cluster via WLST or the Administration Console), any servers or clusters that you subsequently add to the domain via the Configuration Wizard are automatically assigned to the first Coherence cluster that is listed on the Coherence Clusters screen.
