For each type of log file, there is a corresponding data loader component. These components are all of class atg.reporting.datawarehouse.loader.Loader
, and are located in the /atg/reporting/datawarehouse/loaders/
Nucleus folder. The loader components for the Oracle Commerce Platform are:
RegistrationLoader
SiteLoader
SegmentLoader
SiteVisitLoader
UserUpdateLoader
Note that there are data loader components specific to each Oracle Commerce Platform application. Refer to the application documentation for information on these specific components.
