如果尝试创建比较，则会出现Oracle SQL错误

Question

如果我试图跑：

BEGIN
  DBMS_COMPARISON.CREATE_COMPARISON(
    comparison_name => 'compare_docdestruct',
    schema_name     => 'DOCDES',
    object_name     => 'KVT_DOCDESTRUCT',    
    remote_schema_name => 'DOCDES2',    
    remote_object_name => 'KVT_DOCDESTRUCT');
END;

我收到以下错误：

ORA-06550: line 2, column 3:
PLS-00306: wrong number or types of arguments in call to 'CREATE_COMPARISON'
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored
06550. 00000 -  "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.

我不明白问题是什么。你能帮忙吗？
