I tried to start the AdminServer with the node manager using the nmStart('AdminServer') command but got the following error:
Error starting server AdminServer: weblogic.nodemanager.NMException: Exception while starting server 'AdminServer': java.io.IOException: Server failed to start up. See server output log for more details.
As I investigate further, I found the following error message in the AdminServer.log file:
####<Dec 22, 2010 2:58:58 PM GMT+08:00> <Critical> <WebLogicServer> <Alpha002> <AdminServer> <main> <<WLS Kernel>> <1293001138031> <BEA-000386> <Server subsystem failed. Reason: weblogic.security.SecurityInitializationException: Authentication for user denied

Did you check if you have a boot.properties file in this location:
/u0/app/oracle/product/middleware/user_projects/domains/ClassicDomain/servers/AdminServer/data/nodemanager folder ?
If not create a plain text file called boot.properties with contents:
Check if this resolves your issue
I think you need a valid boot.properties under
Node manager should be able to detect boot.properties under any of these folders.

My nm_properties.properties only contains a hashed value similar to the one below:
Is it correct if I simply add:
to it? And also, will it be stored as a clear text? If so, that might pose another problem, security wise.
Besides that, I have also created a boot.properties file at the location that you suggested with the username and password but that did not resolve the problem. Any other suggestions?

Please take a back up of your current m_properties.properties file
Once done, please enter your credentials in plain text
restart Node Manager in order for the changes to take effect.
You will see that the credential will be encrypted. There are no security issues in this.
Let me know if this works for you or not.
If not, kindly upload the NodeManger.properties file and the config.xml

It works! Anyway, I think the reason that it did not work previously is because I did not stop the adminserver before I started it again with the nodemanager...my mistake. Anyway, I also noticed that modifying the nm_password.properties file may not required. I replaced the edited version of the nm_password.properties file with the original one (without username and password) and that still works.
Once again, thanks for your help. Really appreciate it.
