ORA-39001: invalid argument value
ORA-01775: looping chain of synonyms
解决方法：删除SYS_EXPORT_SCHEMA_* 相关的同义词。
SQL> select owner, object_name, object_type, status from dba_objects where object_name like '%SYS_EXPORT_SCHEMA_%' and
OBJECT_TYPE='SYNONYM';
OWNER OBJECT_NAME OBJECT_TYPE STATUS
------------------------------ -------------------- ------------------- -------
PUBLIC SYS_EXPORT_SCHEMA_01 SYNONYM VALID
PUBLIC SYS_EXPORT_SCHEMA_02 SYNONYM INVALID
PUBLIC SYS_EXPORT_SCHEMA_03 SYNONYM INVALID
SQL> drop public synonym SYS_EXPORT_SCHEMA_01;
Synonym dropped.
SQL> drop public synonym SYS_EXPORT_SCHEMA_02;
Synonym dropped.
SQL> drop public synonym SYS_EXPORT_SCHEMA_03 ;
Synonym dropped.
再去导出，就可以了。
