linux 下的 oracle 自动备份脚本

usharkp

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。

最后查看备份结果：

[oracle@T10 ~]$ cat 2011-10-19_arc.log
