Cannot connect to Node Manager. : Access to domain for user ‘weblogic’ denied

January 15, 2012 2 comments

If you’ve hit this error you are probably trying to control your Weblogic servers via WLST, but you are unable to connect to the Node Manager.

Connecting to Node Manager …
Traceback (innermost last):
File “”, line 1, in ?
File “”, line 123, in nmConnect
File “”, line 648, in raiseWLSTException
WLSTException: Error occured while performing nmConnect : Cannot connect to Node Manager. : Access to domain ‘FMW_XPS’ for user ‘weblogic’ denied.

Assuming you’ve already made sure all the parameters in the nmConnect command are correct and the NM process is up and running, there is actually one more thing to check: has your domain been set up in Production Mode? If so, then the Node Manager credentials have been generated by the Configuration Wizard at domain creation time. While the AdminServer will be aware of these credentials by default (you are able to connect to the NM via de admin console, after all), you will not be able to connect via WLST since you have to provide this random username and password. The solution is to reset the credentials in the Administration Console.

What’s new in Oracle Weblogic Server 12c

December 2, 2011 Leave a comment

On December 1st, Oracle has held an online event to launch the new Weblogic Server 12c, the foundation for the future generation of Fusion Middleware products. Along with 200 new features, this release brings cloud computing capabilities, hence the “c” in 12c, an even tighter integration with the Oracle Database and integration with some new Oracle products, that have just been announced.

Below you will find some of the new features that were mentioned during the live launch event:

  • Oracle Traffic Director, is a new released product, that will offer HTTP requests caching, a reverse proxy function and load-balancing based on other algorithms than just round-robin. It will completely replace Oracle WebCache, and while it will also eliminate the need for the Weblogic web server plugins for fronting a Weblogic cluster, the plugins will still be supported by Oracle for integrating with third party web servers such as Apache, IIS etc. However, the Oracle Traffic Director will initially be available only on the Exalogic platform!!
