In the left pane
of the Console, expand Environment and select
Coherence Clusters.
The Summary of Coherence Clusters page
displays the Coherence cluster configurations that have been created
in this domain.
Select the check box next to the name of the cluster
configuration you want to delete.
Click
Delete.
The cluster configuration is removed from the Coherence
Clusters table.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
