以下是oracle导出备份和导入恢复自动产生sql源代码各变量含义为:
      EXP_BACK_DIR:  导出ORACLE数据库的DMP文件所放目录
      SCRIPT_FILE: 此代码所生成的批处理文件路径及文件名称
      LOG_FILE: 导出日志文件存放路径及文件名称
      INT_USER:导出的ORACLE数据库的用户名
      INT_PWD: 导出的ORACLE数据库的用户的口令
      以下代码存成sql文件后
      可以通过COMMAND :sqlplus internal/oracle@sqcdb @产生备份SQL代码的原文件名 <参数> 来运行。

  EXP导出备份SQL源文件

  --You must have select privileges on the v$parameter
  --v$logfile v$datafile and v$controlfile data
  --dictionary views belonging to SYS to run this program

  define EXP_BACK_DIR = e:oradbexpbackups

  set feedback off
  set heading off
  set pagesize 0
  set linesize 128
  set verify off
  set echo off
  col a new_value b
  col c new_value d
  select value a,to_char(sysdate, 'YYYY-MM-DD HH24:MI:SS') c from v$parameter where name ='db_name';

  spool &SCRIPT_FILE
  prompt rem ***** EXP ORACLE DATABASE FOR &INT_USER USER of &b ON WINDOWS NT ON &d*****

  IMP整个用户导入的SQL源文件

  IMP单个表导入的SQL源文件

  --You must have select privileges on the v$parameter
