  以下是oracle冷备份及恢复自动产生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:

  --v$logfile v$datafile and v$controlfile data
  --dictionary views belonging to SYS to run this program

  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';
