Removing a Node
When you remove a node from a domain, it is no longer visible in the Navigator. If the node is running when you remove it, the node shuts down and aborts all application service processes.
Note: To avoid loss of data or metadata when you remove a node, disable all running application service processes in complete mode.
1. In the Administrator tool, click the Manage tab > Services and Nodes view.
2. In the Domain Navigator, select a node.
3. In the Navigator Actions menu, select Delete.
4. In the warning message that appears, click OK.
