-25353: Specified maximum number of LONG data files for column '<column_name>' exceeded 

Explanation:

Error executing the Loader command for exporting data.

In the command, you can set the export_lobcolumn_spec in the syntax element for columns of data type LONG so that each value exported is written in a single data stream (Exporting LONG Values). Placeholders in the data stream name ('#') determine the maximum number of data streams that can be generated. For example, <name>### would mean that 1000 data streams can be generated.

This error occurs if the table contains more data records than the number of data streams that can be generated.

User Response:

Correct the command and then re-execute it.
