我没有两个可用的数据库，所以我将尝试在我的本地 11gXE 上进行。
首先，以特权用户 (SYS) 身份连接，检查我拥有哪些目录并向我将导出和导入的用户授予所需的权限：
SQL> connect sys as sysdba
Enter password:
Connected.
SQL> desc dba_directories
Name Null? Type
----------------------------------------- -------- ----------------------------
OWNER NOT NULL VARCHAR2(30)
DIRECTORY_NAME NOT NULL VARCHAR2(30)
DIRECTORY_PATH VARCHAR2(4000)
SQL> col directory_name format a15
SQL> col directory_path format a60
SQL> select directory_name, directory_path from dba_directories;
DIRECTORY_NAME DIRECTORY_PATH

SQL> grant read, write on directory ext_dir to scott;
Grant succeeded.
SQL> grant read, write on directory ext_dir to mike;

如果我没有任何目录，我会将其创建为
SQL> create directory brisime_dir as 'c:\temp';
Directory created.
SQL> grant read, write on directory brisime_Dir to scott;
Grant succeeded.

并继续...
