Sometimes things go wrong during configuration, and it is often difficult to figure out how to fix them. To help with these situations, Nucleus is able to display messages about the configuration process. Normally, Nucleus only displays messages when there are errors or warnings, but Nucleus can also be instructed to display informative or debugging messages as well. This is controlled by the top-level Nucleus.properties configuration file.
If you recall, this top-level configuration file is where you defined the initialServiceName that is used to specify the first component that Nucleus is supposed to create. Inside this file, you can also define the settings of the logging levels. For example:
initialServiceName=/Initial loggingError=true loggingWarning=true loggingInfo=false loggingDebug=false
This tells Nucleus that it should output error and warning messages, but not informational or debugging messages. This is the default setting in the Nucleus.properties configuration file. If you are having trouble with configuration, set info and/or debug to true and see if the resulting messages are of any help.
You can also change these settings at runtime through the ATG Control Center Components window, by changing the property values of the / component.
Note that these settings apply only to Nucleus, and do not affect the logging settings of other components.
For more information about using the logging system in the ATG platform, see the Dynamo Logging section of the Logging and Data Collection chapter.
