Environment

Novell ZENworks 10 Configuration Management

Situation

novell-zenloader service seems to start, but the only thing logged to the loader-messages.log is:
[Loader.DataModelModule] [Logging into the datamodel (try 1)] [Logging into the datamodel (try 1)] [] []
But not:
Successfully logged in

Resolution

For further troubleshooting messages and startup debugging on, do the following:
  1. Stop the novell zenworks services monitor process.
    For Windows: use the Administrative Tools/services.
    For linux: /etc/init.d/novell-zenmntr stop
  2. Stop the novell zenworks loader process.
    For Windows, use the Administrative Tools/services.
    For linux:/etc/init.d/novell-zenloader stop.
  3. From a command line run the loader explicitly:
    For Windows: "%ZENWORKS_HOME%\bin\zenloader.exe".

    For linux:
    login in as zenworks user so that disrupt file permissions are not disrupted:
    su -s /bin/bash zenworks
    /opt/novell/zenworks/bin/zenloader.
  4. This will output any errors that occur prior to the logger to stdout. To capture the screen run with >outfile.

Additional Information

Examples of problems that may be seen only when manually loading the zenloader:
The following is output if zdm.xml is not available:
