Oracle教程：crontab+RMAN 日期备份脚本

新接手了几个客户的数据库，数据库真是一团糟糕，什么分区，索引，表空间都十分的乱，最重要的是归档都没有开，竟然还是生产库，更别说什么备份脚本了，最近一直在做备份恢复的整理工作，该归档的停机归档，该建立脚本的建立备份脚本，以前库少，现在库多了，管理多个库不能那么空闲了，现在的库之前做了CRONTAB+RMAN的备份，做了些修改，记录如下：

2011-06-21修改RMAN参数以及备份脚本，实现7天后自动删除失效备份集，同时添加定时任务的执行结果到监控邮件。
1：修改RMAN参数修改RMAN失效日期为7天，同时修改自动备份控制脚本参数为开启状态。

4：修改归档脚本修改脚本，添加按日期产生文件夹，
[Oracle@localhost rman]$ vi archback.sh

# user env
source ~/.bash_profile

export BACK_DATE=`date +%Y%m%d`
export BACKUP_PATH=/sdb/opt/rman

echo `mkdir -p ${BACKUP_PATH}/archivelog/${BACK_DATE}`

rman target / nocatalog msglog=$BACKUP_PATH/archivelog/${BACK_DATE}/arch_0_$BACK_DATE.log << EOF

# need a user and tablespace to create catalog
#connect catalog rman/rman@$Oracle_SID;

# resync catalog with target
#resync catalog;

run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
sql 'alter system archive log current';
backup filesperset 3 format '$BACKUP_PATH/archivelog/${BACK_DATE}/arch_level_0_%d_%T_%s_%U' archivelog all delete input;
release channel c1;
release channel c2;
release channel c3;
}

crosscheck backup;
delete noprompt expired backup;
crosscheck archivelog all;
delete noprompt archivelog until time 'sysdate - 1'  all ;
report obsolete;
delete noprompt obsolete;

exit

EOF

# end

5：修改数据备份脚本[Oracle@localhost rman]$ vi fullback.sh

# user env
source ~/.bash_profile

export BACK_DATE=`date +%Y%m%d`
export BACKUP_PATH=/sdb/opt/rman

echo `mkdir -p ${BACKUP_PATH}/rman/${BACK_DATE}`

rman target / nocatalog msglog=$BACKUP_PATH/rman/${BACK_DATE}/bak_0_$BACK_DATE.log << EOF

# need a user and tablespace to create catalog
#connect catalog rman/rman@$Oracle_SID;

# resync catalog with target
#resync catalog;

run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup full database include current controlfile tag 'dbk_level_0' format '$BACKUP_PATH/rman/${BACK_DATE}/df_level_0_%d_%T_%s_%U';
sql 'alter system archive log current';
backup filesperset 3 format '$BACKUP_PATH/rman/${BACK_DATE}/arch_level_0_%d_%T_%s_%U' archivelog all delete input;
release channel c1;
release channel c2;
release channel c3;
}

crosscheck backup;
delete noprompt expired backup;
crosscheck archivelog all;
delete noprompt archivelog until time 'sysdate'  all ;
report obsolete;
delete noprompt obsolete;

exit

EOF
6：修改Crontab任务修改如下，增加定时任务失败日志：
[Oracle@localhost monitor_client]$ crontab -l
30 01 * * 0 "/usr/app/rman/fullback.sh" >/home/Oracle/monitor_client/logs/full_cron.log 2>/home/oracle/monitor_client/logs/full_cron_error.log
00 00 * * 6,1,2,3,4,5 "/usr/app/rman/archback.sh" >/home/Oracle/monitor_client/logs/arch_cron.log 2>/home/oracle/monitor_client/logs/arch_cron_error.log
30 7,15 * * * "/home/Oracle/monitor_client/client_cron.sh" >/home/oracle/monitor_client/client_cron.log 2>/home/oracle/monitor_client/client_cron_error.log
7：邮件监控脚本修改增加传送定时任务错误脚本功能，服务器端接收到数据后解析邮件通知
