---執行過以下腳本
-- 1、建表空間 
CREATE TABLESPACE NNC_DATA01 DATAFILE 'C:\Data\nnc_data01.dbf' SIZE 3G AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K ;
 
CREATE TABLESPACE NNC_INDEX01 DATAFILE 'C:\Data\nnc_index01.dbf' SIZE 3G AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K ;
 
-- 2、建立用戶 
CREATE USER Chen IDENTIFIED BY Chen123456 DEFAULT TABLESPACE NNC_DATA01 TEMPORARY TABLESPACE temp; 

-- 3、爲新建的用戶授權 
GRANT connect,dba to Chen with admin option ; 

-- 4、建立數據泵對應目錄 
CREATE DIRECTORY my_dir AS 'c:\backup';

-- 5、爲所建用戶賦予虛擬目錄的讀寫權限 
grant read,write on directory my_dir to Chen; 

-- 6、備份，恢復
