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：

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。

[oracle@localhost ~]$ rman target /

Recovery Manager: Release 10.2.0.1.0 - Production on Tue Jun 21 13:59:31 2011

connected to target database: GIS (DBID=3650399296)

RMAN> show all;

RMAN configuration parameters are:

CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default

CONFIGURE BACKUP OPTIMIZATION OFF; # default

CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default

CONFIGURE CONTROLFILE AUTOBACKUP OFF;# default

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default

CONFIGURE DEVICE TYPE DISK PARALLELISM 3 BACKUP TYPE TO BACKUPSET;

CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default

CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default

CONFIGURE MAXSETSIZE TO UNLIMITED; # default

CONFIGURE ENCRYPTION FOR DATABASE OFF; # default

CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default

CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default

CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/usr/app/db-server/ora_home/dbs/snapcf_gis.f'; # default

RMAN> CONFIGURE CONTROLFILE AUTOBACKUP on;

new RMAN configuration parameters:

CONFIGURE CONTROLFILE AUTOBACKUP ON;

new RMAN configuration parameters are successfully stored

RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

new RMAN configuration parameters:

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

new RMAN configuration parameters are successfully stored

RMAN> show all;

RMAN configuration parameters are:

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

CONFIGURE BACKUP OPTIMIZATION OFF; # default

CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default

CONFIGURE DEVICE TYPE DISK PARALLELISM 3 BACKUP TYPE TO BACKUPSET;

CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default

CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/usr/app/db-server/ora_home/dbs/snapcf_gis.f'; # default

2：查看过期备份

RMAN> report obsolete;

RMAN retention policy will be applied to the command

RMAN retention policy is set to redundancy 1

Report of obsolete backups and copies

Type Key Completion Time Filename/Handle

-------------------- ------ ------------------ --------------------

Backup Set 2624 19-JUN-11

Backup Piece 2624 19-JUN-11 /sdb/opt/rman/rman/arch_level_0_GIS_20110619_2635_ibmf959t_1_1

Backup Set 2623 19-JUN-11

Backup Piece 2623 19-JUN-11 /sdb/opt/rman/rman/arch_level_0_GIS_20110619_2636_icmf959t_1_1

3：删除过期备份集

RMAN> delete noprompt obsolete;

RMAN retention policy will be applied to the command

RMAN retention policy is set to redundancy 1

allocated channel: ORA_DISK_1

channel ORA_DISK_1: sid=94 devtype=DISK

allocated channel: ORA_DISK_2

channel ORA_DISK_2: sid=137 devtype=DISK

allocated channel: ORA_DISK_3

channel ORA_DISK_3: sid=91 devtype=DISK

Deleting the following obsolete backups and copies:

Backup Piece 2623 19-JUN-11 /sdb/opt/rman/rman/arch_level_0_GIS_20110619_2636_icmf959t_1_1

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
