5 WebLogic Server Machines
Node Manager is a WebLogic Server utility that enables you to start, shut down, and restart Administration Server and Managed Server instances from a remote location. Although Node Manager is optional, Oracle recommends using it if your WebLogic Server environment hosts applications with high availability requirements because Node Manager allows you to control the running state of distributed server instances from a centralized location.
The Java implementation of Node Manager is configured by default to control all server instances belonging to the same domain, a per domain Node Manager. The server instances need not reside on the same machine. For more information about Node Manager, see Administering Node Manager for Oracle WebLogic Server.
Note:
If you are logged into a domain partition, navigate from the Domain Partition menu. Note that WebLogic Server Multitenant domain partitions, resource groups, resource group templates, and virtual targets are deprecated in WebLogic Server 12.2.1.4.0 and will be removed in the next release.
