ORA-39001: invalid argument value
ORA-01775: looping chain of synonyms


FIX:


SQL> Select owner, object_name, object_type, status   from dba_objects  where object_name like '%SYS_EXPORT%';

OWNER
--------------------------------------------------------------------------------
OBJECT_NAME
--------------------------------------------------------------------------------
OBJECT_TYPE             STATUS
----------------------- -------
PUBLIC
SYS_EXPORT_SCHEMA_01
SYNONYM                 VALID

SYSTEM
SYS_EXPORT_TABLE_01
TABLE                   VALID

connect / as sysdba
drop public synonym sys_export_schema_01;

Now rerun export again

(OR)

If you dont want to drop the table now then give some job name ( job_name=<JOB_NAME>" ) and run the export
