EXP-00073: dump file size too small
What triggered the Error:
You specified either the FILESIZE parameter or the VOLSIZE parameter (if your platform supports it), and the value of the parameter is too small to hold the header information for the export file, plus any data.What should we do to fix it:
Increase the value of the FILESIZE or VOLSIZE parameter.
