以下是oracle冷备份恢复自动产生sql源代码,各变量含义为:

  COLD_BACK_DIR: 冷备份目录
  SCRIPT_FILE: 此代码所生成的批处理文件路径及文件名称
  LOG_FILE: 备份日志文件存放路径及文件名称
  INT_PWD: internal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。
  
  冷备份SQL源代码如下:

--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 COLD_BACK_DIR = e:\oradb\coldbackups
  define SCRIPT_FILE = e:\back\coldbackup.bat
  define LOG_FILE= e:\back\coldbackup.log
  define INT_PWD = oracle
  set pages 0 feed off echo off time off
  set verify 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 ***** COLDBACKUP ORACLE DATABASE FOR &b ON WINDOWS NT ON &d*****
  prompt
  prompt set ShutDownFile=C:\ShutDown.SQL
  prompt echo connect internal/&INT_PWD > %ShutDownFile%

  prompt exit
  
  spool off
  
  $&SCRIPT_FILE
  $del &SCRIPT_FILE
  exit
