考虑到系统是高可用性系统（7×24），因此采用rman来热备份db，具体备份步骤部署如下：
把db改为归档模式，2个节点的归档日志分别放在各自的/orabak/archlog目录下
把db的备份文件放在2个节点各自的/orabak/dbbak目录下，每次备份的文件会分布在2个节点上，这样做的目的对2个节点来说相对都能节约一些空间，因为/orabak目前暂时挂载在rootvg下了，由于datavg里已经没有了空间
备份脚本存放在节点1的/orabak/script里面
A．具体os层面的备份脚本是/orabak/script/dbbak.sh，内容如下：
--环境变量设置，最简单的办法就是把oracle用户的环境变量文件.profile的内容全部拿过来即可
PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:.
export PATH
if [ -s "$MAIL" ] # This is at Shell startup. In normal
then echo "$MAILMSG" # operation, the Shell checks

rman target / cmdfile='/orabak/script/dbbak.sql' log='/orabak/script/dbbak.log' append < B．os层面的备份脚本/orabak/script/dbbak.sh调用的db层面的脚本/orabak/script/dbbak.sql内容如下： run{ allocate channel c1 device type disk connect sys/system@racdb1; allocate channel c2 device type disk connect sys/system@racdb2; backup as compressed backupset database format='/orabak/dbbak/racdb_%T_%U.bak'; delete noprompt obsolete; crosscheck backup; crosscheck archivelog all; delete noprompt expired backup; delete noprompt expired archivelog all; backup as compressed backupset archivelog all format='/orabak/dbbak/archlog_%T_%U.bak'; } exit; EOF 每天晚上11：30系统自动备份db，具体实现脚本如下： 30 23 * * * /orabak/script/dbbak.sh 5．受到/orabak目录所在的rootvg的空间限制，我们制定了备份保留3天的策略，db的备份和归档以及归档日志的备份保留3天之后自动删除，具体备份策略如下： $ rman target / Recovery Manager: Release 11.1.0.6.0 - Production on Wed Jun 9 16:24:41 2010 Copyright (c) 1982, 2007, Oracle.

大哥 那个ibm R＆Ｒ软件“把C:IBMSHARE下的文件ibmpwhp.pyc请空，不要删除” 我吧文件删除了 怎么再生成一个呢？
