Before you begin
Ensure that you have created a cluster and assigned Managed Servers to it.
For information on creating a Managed Server, see Create Managed Servers.
To start Managed Servers in the Standby or Admin mode, see Specify a startup mode.
Node Manager is a stand-alone Java program provided with each WebLogic Server installation. You use it to start, stop, and suspend server instances, and to automatically restart servers that fail. Node Manager must run on each computer that hosts WebLogic Server instances that you want to control with Node Manager. Configure each computer as a machine in WebLogic Server, and assign each server instance that you will control with Node Manager to the machine upon which it runs. See:
For more information about Node Manager, see Administering Node Manager for Oracle WebLogic Server.
Although running Node Manager as an operating system service is recommended, you can also start Node Manager manually at the command prompt or with a script. See Administering Node Manager for Oracle WebLogic Server.
The Summary of Clusters table displays all the clusters defined in the domain.
Node Manager starts the server on the target machine. When Node Manager finishes its start sequence, the server's state is indicated in the State column in the Managed Server Instances in this Cluster table.
When an operation is complete for a Managed Server, TASK COMPLETED appears in the Status column.
