If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
In the left pane
of the Console, expand Environment and select
Coherence Servers.
The Coherence servers table displays all the Coherence servers
defined in the domain.
Select the check box next to the name of the server you want to
delete and click Delete.
The selected server is removed from the Summary of Coherence
Servers 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).
