How To Start/Stop NodeManager Using WLST?

1) Starting NodeManager using WLST

Syntax:

startNodeManager([verbose], [jvmArgs], [nmProperties])
- verbose = Optional. Boolean value specifying whether WLST starts
 Node Manager in verbose mode. This argument defaults to false, disabling
 verbose mode.

- jvmArgs = Optional. JVM arguments to pass to the NodeManager process.
 Multiple arguments can be specified, separated by commas.

- nmProperties = Optional. Comma-separated list of Node Manager properties,
 specified as name-value pairs. Node Manager properties include, but are not
 limited to, the following: NodeManagerHome, ListenAddress, ListenPort, and
 PropertiesFile.

NOTE: In order to stop the Node Manager process,
you must have either started Node Manager with startNodeManager or
Node Manager must have been started with the property QuitEnabled=true.
You can configure this property in
$DOMAIN_HOME/nodemanager/nodemanager.properties file.
This allows you to connect to the Node Manager and shut it down.

Example: 

startNodeManager(verbose='true',NodeManagerHome='/oracle/Middleware/user_projects/domains/prod_domain/nodemanager',ListenPort='5556',ListenAddress='192.168.145.128',jvmArgs='-Xms24m,-Xmx64m')

2) Stopping NodeManager Using WLST

     a) Connecting To NodeManager

wls:/offline> nmConnect('weblogic','welcome1','192.168.145.128','5556','prod_domain','/oracle/Middleware/user_projects/domains/prod_domain','plain')

    b) Stopping NodeManager

wls:/nm/prod_domain> stopNodeManager()
