z You can choose which software components to install on your system. For a description of

are created only for the installed components.
Note: You must choose Custom installation to install the Web Server Plug-ins.
z You can choose whether to install the WebLogic Server Node Manager as a Windows
Service. See “About Installing Node Manager as a Windows Service” on page 1-19.

1.5.0. For more information, see “BEA JRockit JDK” on page 1-6.
About Installing Node Manager as a Windows Service
When installing your software on a Windows platform, you can optionally install WebLogic
Server Node Manager as a Windows service. The WebLogic Server Node Manager is used to:
z Start and stop server instances—both Administration Servers and Managed Servers—
remotely.
z Monitor the self-reported health of servers and automatically kill server instances whose
health state is “failed.”
z Migrate servers in a WebLogic Server cluster.
z Automatically restart servers that have the “failed” health state, or have shut down
unexpectedly due to a system crash or reboot.
In a multi-machine environment, you must install Node Manager on each machine that hosts
Managed Server and Administration Server instances of WebLogic Server.
Note: You must have Administrator privileges to install Node Manager as a Windows service.
In a custom installation, you can optionally install Node Manager as a Windows service. If you
select Yes, Node Manager is installed as a Windows service to Listen Port 5556. To avoid port
contention, you can specify an alternate Listen Port if desired. If the Listen Port number you
specify is currently being used by a running application, the installation program prompts you to
enter a different Node Manager Listen Port number. At the completion of the installation process,
Node Manager is started using the port specified.
