(转载)Linux环境下rman备份的实例脚本

背景：目标数据库192.168.1.172   Redhat Linux AS 3.0   Oracle 9.2.0.6
          恢复目录数据库 192.168.1.244   Windows2000   Oracle 9.2.0.1 rman/rman

1、配置catalog恢复目录
    create tablespace ts_rman datafile='d:oratestrman.dbf' size=100M;
    create user rman identified by rman default tablespace ts_rman;
    grant connect ,resource , RECOVERY_CATALOG_OWNER to rman;
   
    连接到目标数据库和CATALOG数据库
    rman target / catalog
   
    创建CATALOG用户的表,登记目标数据库
    rman> create catalog
    rman> register database
   
    配置参数
    rman> configure controlfile autobackup on;
    rman> configure backup optimization on;

2、rman备份方案
    每周日晚做一次零级备份，周一到周六做一次一级备份
   
************************************************************************
***                           rman_bk_L0.sh                            ***
************************************************************************
#!/bin/sh

source /home/oracle/.bash_profile

cd $ORACLE_HOME/bin

./rman target / catalog msglog=/home/oracle/work/log/rman_bk_L0_`date '+%Y%m%d%H%M%S'`.log <

run {
allocate channel c1 type disk;
backup incremental level 0 filesperset 5 tag 'dbL0' format '/mnt/raid/rman_bk/ora_o_%d_%t%s%p%u' database skip readonly;
sql 'alter system archive log current' ;
backup(archivelog all format '/mnt/raid/rman_bk/ora_a_%d_%t%s%p%u');
release channel c1;
}

list backup;
exit;

EOF

************************************************************************
***                           rman_bk_L1.sh                            ***
************************************************************************
#!/bin/sh

source /home/oracle/.bash_profile

cd $ORACLE_HOME/bin

./rman target / catalog msglog=/home/oracle/work/log/rman_bk_L1_`date '+%Y%m%d%H%M%S'`.log <

run {
allocate channel c1 type disk;
backup incremental level 1 filesperset 5 tag 'dbL1' format '/mnt/raid/rman_bk/ora_o_%d_%t%s%p%u' database skip readonly;
sql 'alter system archive log current' ;
backup(archivelog all format '/mnt/raid/rman_bk/ora_a_%d_%t%s%p%u');
release channel c1;
}

list backup;
exit;

EOF

然后使用crontab命令在linux上安排job如下：

00 02 * * 0 /home/oracle/work/bin/rman_bk_L0.sh
00 02 * * 1,2,3,4,5,6 /home/oracle/work/bin/rman_bk_L1.sh

注意：每周一要将冗余的备份手工清除掉
rman> report obsolete;
rman> delete obsolete;
