<Error> <NodeManager> <BEA-300033> <Could not execute command “getVersion” on the node manager. Reason: “Access to domain ‘Test_Domain’ for user ‘DTXezFTI’ denied”.>

Resolution Steps:

By default node manager log level is Info .
First we have to set the log level to Finest.(if you configured the logging as finest... you will get more information in logs) 

We have few other log levels available for Node Manager :

SEVERE          
WARNING
INFO                
CONFIG
FINE
FINER
FINEST             

After  changes restart the Node Manager and check for the log file error message again.

Solution :

1 : Log on to the Admin console ( http://AdminserverIP:Port/console )

2 : click on  Domain Name (Test_Domain) in my case >>>>> Then to security >>>>

3 : Click on the Advance Option for change the username & password values to use nodemanager.

Let's an example

username is : weblogic 

password is : welcome123

4 : save the changes.

Then we have to edit the nodemanager properties of each remote host(with in domain):

·         Navigate to the folder %DOMAINHOME%\config\nodemanager

·         Edit the file: nm_password.properties with updated credentials

·         username=weblogic

·         password=welcome123

·         Save

·         Restart the Weblogic Node Manager

5 : Then navigate to the Test_Domain/servers/mannaged_server/data/nodemanager/ dir.

6 : open the boot.properties file and enter the below values :

username=weblogi & password= welcome123

7: Restart the your Admin Server.

8 : Now run the nmEnroll() wlst command for all the machines that has the Managed server.

wlst>connect(‘username’,'password’,'t3://admin_host:admin_port’)

online>>nmEnroll(‘Domain_dir_path’,'NodeManager_Home_Path’)

online>>exit()

Now you can check the node manager status from Admin Console .

left panel >> Machines >> Machine1 >> Monitoring >>

The Status should be reachable.
