Oracle DMP备份文件导入(impdp)导出(expdp)步骤

Oracle DMP备份文件导入(impdp)导出(expdp)方法
一  impdp 导入

     --删除用户若用户已经存在（可以使用Oracle自带的sqlplus进行连接）
SQL> drop user USER_NAME cascade
SQL> /
SQL> drop tablespace USER_TABLESPACE including contents and datafiles
SQL> /

     --创建表空间
SQL> CREATE TABLESPACE USER_TABLESPACE DATAFILE 'USER_tablespace.DBF' SIZE 200M AUTOEXTEND ON NEXT 50M MAXSIZE UNLIMITED PERMANENT DEFAULT STORAGE(INITIAL 64K MINEXTENTS 1 MAXEXTENTS 2147483645) MINIMUM EXTENT 64K LOGGING ONLINE
SQL> /

     --创建用户
SQL> CREATE USER USER_NAME IDENTIFIED BY user_password DEFAULT TABLESPACE USER_TABLESPACE TEMPORARY TABLESPACE TEMP PROFILE DEFAULT
SQL> /
     --创建用户目录
SQL> CREATE DIRECTORY directory_name  as 'filePath' 
SQL> /
      --示例 my_dir as 'D:/db_dir'
    
     --为用户授权
SQL> GRANT CONNECT TO USER_NAME WITH ADMIN OPTION
SQL> /
SQL> GRANT DBA TO USER_NAME WITH ADMIN OPTION
SQL> /
SQL> GRANT UNLIMITED TABLESPACE TO USER_NAME WITH ADMIN OPTION
SQL> /
SQL> GRANT read, write ON DIRECTORY directory_name TO USER_NAME
SQL> /

     --执行导入（退出sqlplus在CMD执行导入语句）
impdp USER_NAME/user_password@SID_NAME directory=directory_name dumpfile=USER_NAME.DMP schemas=USER_NAME logfile=USER_NAME.log;
pause;

二 expdp 导出

expdp USER_NAME/user_password@SID_NAME directory=directory_name dumpfile=USER_NAME.DMP schemas=USER_NAME logfile=USER_NAME.log;
pause;
