linux 下的 oracle 自动备份脚本

作者佚名技术来源 Linux系统浏览发布时间 2012-03-25

这个脚本比较简单：周天对数据库进行全备,周一到周六进行归档日志备份. [oracle@T10 ~]$ cat backup.sh
#!/bin/bash
#oracle backup script
btime=`date %A`
export ORACLE_SID=snzo
export ORACLE_HOME=/u01/oracle/product/10g/db
if [ $btime = "Sunday" ] ; then
/u01/oracle/product/10g/db/bin/rman target / cmdfile=/home/oracle/datafile.sql log=/home/oracle`date %Y-%m-%d`_dbf.log
else
/u01/oracle/product/10g/db/bin/rman target / cmdfile=/home/oracle/archive.sql log=/home/oracle/`date %Y-%m-%d`_arc.log
fi 备份数据库的数据库脚本：
[oracle@T10 ~]$ cat datafile.sql
run
{
allocate channel ch1 type disk;
allocate channel ch2 type disk;
backup database format ''/u01/oracle/backup/%U_%T.dbf''; backup archivelog all delete input format ''/u01/oracle/backup/%U_%T.arc'';
release channel ch1;
release channel ch2;
}
exit 备份归档日志的脚本：
[oracle@T10 ~]$ cat archive.sql
run
{
allocate channel ch1 type disk;
backup archivelog all delete input format ''/u01/oracle/backup/%U_%T.arc'';
release channel ch1;
}
exit 设置crontab： [oracle@T10 ~]$ crontab -l
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/u01/orace/product/10g/db/bin
HOME=/home/oracle
*/5 * * * * /home/oracle/backup.sh 此处为测试,没5分钟进行一次备份.

查看备份结果： [oracle@T10 ~]$ cat 2011-10-19_arc.log Recovery Manager: Release 10.2.0.4.0 - Production on Wed Oct 19 16:55:01 2011 Copyright (c) 1982, 2007, Oracle. All rights reserved. connected to target database: SNZO (DBID=2088621957) RMAN> run
