To remove a server instance from a cluster without deleting the
server instance from the domain:
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, select Environment >
Servers.
The Summary of Servers table displays all the server instances
defined in the domain.
In the Servers
table, select the server instance you want to remove from a
cluster.
Select
Configuration>
General.
In
Cluster, select
(Stand-Alone) from the drop-down menu to remove
the server instance from the cluster.
Click Save.
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).
