Install, Configure, and Run - Oracle WebLogic Server 12c Advanced Administration - page 10

Getting ready
The Node Manager is already installed with WebLogic Server 12 c . There are two versions of
the Node Manager: a Java version and a script version. This recipe will cover the Java version.
The Java version is the most commonly used version, and it is more complete and more
secure than the script version.
How to do it...
1. Log in as a wls user on the first machine prod01 and navigate to the folder:
[wls@prod01]$ cd $WL_HOME/server/bin
2. Start the Node Manager in the background. Since it's the first time you are
starting it, the $WL_HOME/common/nodemanager/nodemanager.properties
file will be created.
[wls@prod01]$ nohup ./startNodeManager.sh &
[1] <PID>
nohup: appending output to `nohup.out'
3. Do the same on the prod02 machine and on all the machines of the
WebLogic domain.
How it works...
You can leave the default values created for nodemanager.properties .
The Node Manager has started and is listening to port 5556 . The <PID> value is the number
of the newly created process.
Since the prod01 and prod02 machines were configured when you created the WebLogic
domain PROD_DOMAIN , the Node Manager should be reachable and able to receive start and
stop commands from the Administration Console.

In this section, we will see how to shut down the Node Manager:
Shutting down the Node Manager
There is no formal command to shut down the Node Manager, so you'll have to do it manually,
killing the process:
