ORA-01403: no data found
ORA-06512: at "SYS.DBMS_AQ_IMPORT_INTERNAL", line 77

EXP-00000: Export terminated unsuccessfully

This is what the documentation says:
// *Cause: Backtrace message as the stack is unwound by unhandled
// exceptions.
// *Action: Fix the problem causing the exception or write an exception
// handler for this condition. Or you may need to contact your
// application administrator or DBA.



I don't understand it???
