-25329: The given data file '<file_name>' was not generated using EXPORT in PAGE Format (<error_text>) 

Explanation:

Error in the Loader command for importing data.

The data streams for this command must be binary and contain database structures and special information on executing the subsequent IMPORT command. These data streams are created using the EXPORT command and must not be modified.

The data stream specified in the command was modified after the export was executed or it was not created using the EXPORT command. In the cause of the error section you see which information in the data stream cannot be evaluated.

User Response:

Create the data stream using the EXPORT command and re-execute the command.
