Control Admin Server Using Node Manager and WLST

Control AdminServer with Node manager in WLST

Hey all, here we are going to know about the start and stop of admin server with node manager nm commands using WLST.

Controlling WebLogic Servers with Node Manager using WLST

 Here are the brief steps we are going to follow.

1.    Start Node manager        -  startNodeManager()
2.  Connect to node manger   - nmConnect()
3.Connect and Enroll to admin server    - connect() ,nmEnroll()
4.Start and Stop admin server            - nmStart(),nmKill()
        -

Step 1: Start Node Manager

Start Node Manager using below command. Provide the argument values from “nodemanager.properties” file under node manger home

wls:/offline> startNodeManager(verbose='true', NodeManagerHome='/u01/app/oracle/fmw/demodomain/nodemanager',
ListenPort='5557',ListenAddress='192.168.33.100')

StartNodeManager

Step 2: Connect to node manager using WLST

Connect WLST offline and type help('nmConnect') to get syntax. Syntax:    nmConnect([username, password], [host], [port], [domainName], [domainDir], [nmType], [verbose])

wls:/offline> nmConnect('weblogic','Welcome1','192.168.33.100','5557','demodomain', nmType='plain')
 Connecting to Node Manager ...

Successfully Connected to Node Manager.

nmConnect

Note :- If your node manager not already started nmConenct result following error.

STEP3: Connect to admin server and Enroll(One time activity)

NM connect result will be successful when admin server is running.

3.a. Connect

wls:/nm/demodomain> connect()
Please enter your username :weblogic
Please enter your password :Welcome1
Please enter your server URL [t3://localhost:7001] :t3://192.168.33.100:7001
t3://192.168.33.100:7001
Connecting to t3://192.168.33.100:7001 with userid weblogic ...
Successfully connected to Admin Server "demoadmin" that belongs to domain "demodomain".
Warning: An insecure protocol was used to connect to the server.
To ensure on-the-wire security, the SSL port or Admin port should be used instead.

3.b. Node Manager Enroll
Syntax : nmEnroll('c:/nmdomain')

wls:/demodomain/serverConfig/> nmEnroll('/u01/app/oracle/fmw/demodomain')
Enrolling this machine with the domain directory at /u01/app/oracle/fmw/demodomain ...Successfully
enrolled this machine with the domain directory at /u01/app/oracle/fmw/demodomain.

Step 4: Start and Stop admin server

Start Syntax: - nmStart('<ADMIN SERVER')

Stop Syntax:- nmKill('<ADMIN SERVER')

wls:/nm/demodomain> nmStart('demoadmin')
Starting server demoadmin ...
Successfully started server demoadmin ...

Terminating the admin server using nmKill() command in WLST

wls:/nm/demodomain> nmKill('demoadmin')
Killing server demoadmin...
Successfully killed server demoadmin..

nmStart and nmStop
