linux 下的 oracle 自动备份脚本
<DIV>这个脚本比较简单：</DIV><DIV>周天对数据库进行全备，周一到周六进行归档日志备份。</DIV>
<DIV>$ cat backup.sh <BR>#!/bin/bash<BR>#oracle backup script<BR>btime=`date +%A`<BR>export ORACLE_SID=snzo<BR>export ORACLE_HOME=/u01/oracle/product/10g/db<BR>if [ $btime = "Sunday" ] ; then<BR> /u01/oracle/product/10g/db/bin/rman target / cmdfile=/home/oracle/datafile.sql log=/home/oracle`date +%Y-%m-%d`_dbf.log<BR>else<BR> /u01/oracle/product/10g/db/bin/rman target / cmdfile=/home/oracle/archive.sql log=/home/oracle/`date +%Y-%m-%d`_arc.log<BR>fi</DIV>
<DIV>备份数据库的数据库脚本：<BR>$ cat datafile.sql <BR>run<BR>{<BR>allocate channel ch1 type disk;<BR>allocate channel ch2 type disk;<BR>backup database format '/u01/oracle/backup/%U_%T.dbf';</DIV>
<DIV>backup archivelog all delete input format '/u01/oracle/backup/%U_%T.arc';<BR>release channel ch1;<BR>release channel ch2;<BR>}<BR>exit</DIV>
<DIV>备份归档日志的脚本：<BR>$ cat archive.sql <BR>run<BR>{<BR>allocate channel ch1 type disk;<BR>backup archivelog all delete input format '/u01/oracle/backup/%U_%T.arc';<BR>release channel ch1;<BR>}<BR>exit</DIV>
<DIV>设置crontab：</DIV>
<DIV>$ crontab -l<BR>SHELL=/bin/bash<BR>PATH=/sbin:/bin:/usr/sbin:/usr/bin:/u01/orace/product/10g/db/bin<BR>HOME=/home/oracle<BR>*/5 * * * * /home/oracle/backup.sh</DIV>
<DIV>此处为测试，没5分钟进行一次备份。</DIV>
<DIV>最后查看备份结果：</DIV>
<DIV>$ cat 2011-10-19_arc.log </DIV>
