Loader Log file: Loader logs its export and import actions in the log file loader_<timestamp>.log or loader.log.

Loader Transformation History: When working in transport mode, the loader creates a transformation history transport.log in addition to the log file.

Additional Log Functions (package_spec): You can obtain a detailed log of a single Loader command using the syntax element package_spec.

Loader System Tables: Depending on the data volume, transporting data can take a considerable amount of time. Loader can restart the action if it is interrupted by evaluating the information in the system tables.
