一、背景：
具体的场景是数据库不是普通的OLTP系统，更像是OLAP系统，数据的更新频率很低，在noarchivelog 模式下运行，实时性要求低，但是数据只有一份不能弄丢，需要应付磁盘损坏等情况。这应该是冷备的一个比较好的应用场景。
二、规划：
将数据库服务器多挂载一块磁盘。查出Oracle datafile,controlfile,spfile,redologfile,tempfile的具体位置，拼凑出bat命令，在sqlplus上执行。通过windows的任务计划定时调度。
三、详细步骤：
1.创建sql脚本：
set feedback off set heading off set verify off set trimspool off set pagesize 0 set linesize 200 define dir = ‘G:\oraclebackup\InstanceNames\LUOYI\coolback‘ define script = ‘G:\oraclebackup\InstanceNames\LUOYI\coolback\coolbak.sql‘ spool &script select ‘ho copy ‘ || name || ‘ &dir‘ from v$controlfile union all select ‘ho copy ‘ || name || ‘ &dir‘ from v$datafile union all select ‘ho copy ‘ || member || ‘ &dir‘ from v$logfile union all select ‘ho copy ‘ || name || ‘ &dir‘ from v$tempfile / create pfile = ‘&dir/initLUOYI.ora‘ from spfile; spool off shutdown immediate start &script startup exit /
2.创建批处理脚本：
@echo *********************** >>G:\oraclebackup\InstanceNames\cool_back.log @echo LUOYI backup is start >>G:\oraclebackup\InstanceNames\cool_back.log @echo %date% >>G:\oraclebackup\InstanceNames\cool_back.log @echo %time% >>G:\oraclebackup\InstanceNames\cool_back.log @echo *********************** >>G:\oraclebackup\InstanceNames\cool_back.log set ORACLE_SID=LUOYI del /S /Q G:\oraclebackup\InstanceNames\LUOYI\coolback sqlplus "/as sysdba" @G:\oraclebackup\InstanceNames\LUOYI\LUOYI_cool_backup.sql >>G:\oraclebackup\InstanceNames\cool_back.log @echo *********************** >>G:\oraclebackup\InstanceNames\cool_back.log @echo LUOYI backup is finished >>G:\oraclebackup\InstanceNames\cool_back.log @echo %date% >>G:\oraclebackup\InstanceNames\cool_back.log @echo %time% >>G:\oraclebackup\InstanceNames\cool_back.log @echo *********************** >>G:\oraclebackup\InstanceNames\cool_back.log @echo ------------------------------------------------------------------------
3.创建任务计划调度。
