WLST -I : Weblogic Useful WLST Commands

WLST ( Weblogic Scripting Tool )


How to invoke WLST 


Go to your_domain/bin and run below command

D:\Oracle\Middleware\user_projects\domains\base_domain\bin>java weblogic.WLST

What if you are getting below error just after invoking WLST

Exception in thread "main" java.lang.NoClassDefFoundError: weblogic/WLST

Caused by: java.lang.ClassNotFoundException: weblogic.WLST

Run D:\Oracle\Middleware\user_projects\domains\base_domain\bin>setDomainEnv.cmd

Now you would able to connect with java weblogic.WLST command

Start Node Manager

startNodeManager(verbose="true",NodeManagerHome="D:/Oracle/Middleware/wlserver_10.3/common/nodemanager",ListenPort="5557",ListenAddress="localhost")

where -

Node Manager Home - D:/Oracle/Middleware/wlserver_10.3/common/nodemanager

Node Manager Host host - localhost

Node Manager port - 5557

Connect with node manager

nmConnect("weblogic","webl0gic","localhost","5557","base_domain","D:/Oracle/Middleware/user_projects/domains/base_domain","plain")

To check if you already connect with node manager or not

nm()

Output

wls:/JJTU_Domain1/serverConfig> nm()
Currently connected to Node Manager to monitor the domain JJTU_Domain1.

Start Admin server using node manager

nmStart("AdminServer")

where "AdminServer" is the name of your admin server.

Check Admin Server Status unsing nodemanager

nmServerStatus('AdminServer')

where "AdminServer" is the name of your admin server.

Connect to Admin Server

connect("weblogic","webl0gic","localhost:7001")

where -

admin user - weblogic

admin password=webl0gic

weblogic host - localhost

admin port - 7001

Start Managed Server using nodemanager

nmStart('server_name')


Output
wls:/JJTU_Domain1/serverConfig> nmStart('C_Server1')
Starting server C_Server1 ...
Successfully started server C_Server1 ...

Start Managed Server 

Start(“MS1”) 

Where MS1 is the name of your managed server

To kill server using node manager

nmKill('server_name')

Output

wls:/JJTU_Domain1/serverConfig> nmKill('C_Server1')
Killing server C_Server1 ...
Successfully killed server C_Server1 ...


To check node manager status

nmVersion()

Output

wls:/JJTU_Domain1/serverConfig> nmVersion()
The Node Manager version that you are currently connected to is 10.3.


Domain enrollment with nmEnroll()

nmEnroll()

NmEnroll is used to enroll a machine or you can say to enroll a domain with the node manager because if you have multiple domains ( of different installer ) running on a host then you can handle all with a single node manager but you have have to enroll each domain with the same node manager. 

This is applicable if you have domains from different oracle_home or you can say from different installer on same host ( means you have more than one installation of weblogic on same host with each installer having its different host ).

If you are creating multiple domains from single installer then no need to enroll because it will enroll automatically. 

So to enroll a machine or domain with a particular node manager, follow below steps

1. Start Admin server of domain which you want to enroll with node manager

2. Go to wlst prompt ( go to your_domain, run setDomainEnv and then "java weblogic.WLST")

3. Connect with admin server
    connect("user","password","host:admin_port")

4. Run nmEnroll command
    nmEnroll('C:/Oracle/Middleware/wlserver_12.1/common/nodemanager')

   Where "C:/Oracle/Middleware/wlserver_12.1/common/nodemanager" is the node manager    
   home of node manager with which you want to enroll your domain

5. Update nodemanager.domains under node manager home and add your domain path in     
    same format as earlier domains path there, like below i have added domain in red

     JJTU_Domain1=C\:\\Oracle\\Middleware2\\user_projects\\domains\\JJTU_Domain1
     base_domain=C\:\\Oracle\\Middleware2\\user_projects\\domains\\base_domain   

6. Update node manager password ( username also if not correct there ) from admin console
    ( login to admin console > click on your domain name on left hand side > click on security tab  
     on right hand side > click on Advance link > update node manager password ( username 
     also if not correct there )


Now you can able to connect with node manager


wls:/base_domain/serverConfig> nmConnect("weblogic","weblogic123","localhost","40046","base_domain","C:/Oracle/Middleware2/user_projects/domains/base_domain","plain")
Connecting to Node Manager ...
Successfully Connected to Node Manager.


Note 1 - 

If you are getting below error during connect with node manager, then it means you haven't changed username,password for nodemanager from admin console ( above step 6 )

WLSTException: Error occured while performing nmConnect : Cannot connect to Node Manager. : Access to domain 'base_domain' for user 'weblogic' denied

Note 2 - 

If you are getting below error during connect of node manager then it mean you haven't followed above defined steps OR haven't added your domain on nodemanager.domains


WLSTException: Error occured while performing nmConnect : Cannot connect to Node Manager. : Configuration error while reading domain directory

Disconnect from node manager

nmDisconnect() 

Output()

wls:/JJTU_Domain1/serverConfig> nmDisconnect()
Successfully disconnected from Node Manager.


Stop Node Manager

stopNodeManager()

Output

wls:/JJTU_Domain1/serverConfig> stopNodeManager()
Stopped NodeManager successfully

Important Note :

In order to stop the Node Manager process, Node Manager must have been started with the property QuitEnabled=true. You can configure this property in $WLS_HOME/common/nodemanager.properties. This allows you to connect to the Node Manager to shut it down.

Deleting MDS Artifacts

Use WLST scripts
The WLST script is located at:
(UNIX) MIDDLEWARE_HOME/ORACLE_SOA1/common/bin/wlst.sh(Windows) MIDDLEWARE_HOME\Oracle_SOA1\common\bin\wlst.cmd

Once the scripting tool is initialized, Connect to the server

offline>connect(‘username,’pwd’, ‘hostname:7001’)

For running deleteMetada function you need a minimum of 3 inputs
- application - since we are deleting from shared artifacts of soa-infra, the value should be soa-infra
- server - value should be ‘soa_server1’ or the server u use for SOA other than admin server.
- docs – the folder path or artifact which you want to delete.
wls:/GEO_domain/serverConfig> deleteMetadata(application='soa-infra',server='soa
_server1',docs='/apps/dvm/oracle/dvm/*')

Executing operation: deleteMetadata.

Operation "deleteMetadata" completed. Summary of "deleteMetadata" operation is:

List of documents successfully deleted:
/apps/dvm/oracle/dvm/GeoXRef.dvm

Hope this helps :)
