RMAN_Oracle RMAN的常用configure配置

2014-12-09 BaoXinjian

1. 显示当前的配置信息

1.01 RMAN> show all;

1.02 查询RMAN设置中非默认值:

SQL> select name,value from v$rman_configure;

2. 常用的configure选项

2.01 保存策略 (retention policy)

configure retention policy to recovery window of 3 days;

configure retention policy to redundancy 3;

configure retention policy clear;

备份策略保持

分为两个保持策略，一个是时间策略，决定至少有一个备份能恢复到指定的日期，一个冗余策略，规定至少有几个冗余的备份。

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 5 DAYS;

CONFIGURE RETENTION POLICY TO REDUNDANCY 5;

CONFIGURE RETENTION POLICY TO NONE;

在第一个策略中， 是保证至少有一个备份能恢复到Sysdate-5 的时间点上，之前的备份将标记为Obsolete。

第二个策略中, 说明至少需要有三个冗余的备份存在，如果多余三个备份以上的备份将标记为冗余。

第二个策略中NONE, 可以把使备份保持策略失效，Clear 将恢复默认的保持策略

2.02 备份优化 backup optimization

configure backup optimization on;

configure backup optimization off;

configure backup optimization clear;

2.03 默认设备 default device type

configure default device type to disk;

configure default device type to stb;

configure default device type clear;

2.04 控制文件 controlfile

configure controlfile autobackup on;

configure controlfile autobackup format for device type disk to ‘‘/cfs01/backup/conf/conf_%F‘‘;

configure controlfile autobackup clear;

configure controlfile autobackup format for device type disk clear;

configure snapshot controlfile name to ‘‘/cfs01/backup/snapcf/scontrofile.snp‘‘;

configrue snapshot controlfile name clear;

2.05 并行数(通道数) device type disk|stb pallelism n;

configure device type disk|stb parallelism 2;

configure device type disk|stb clear;

configure channel device type disk format ‘‘e/:rmanback_%U‘‘;

configure channel device type disk maxpiecesize 100m

configure channel device type disk rate 1200K

configure channel 1 device type disk format ‘‘e/:rmanback_%U‘‘;

configure channel 2 device type disk format ‘‘e/:rmanback_%U‘‘;

configure channel 1 device type disk maxpiecesize 100m

2.06 生成备份副本 datafile|archivelog backup copies

configure datafile backup copies for device type disk|stb to 3;

configure archivelog backup copies for device type disk|stb to 3;

configure datafile|archivelog backup copies for device type disk|stb clear

BACKUP DEVICE TYPE DISK DATABASE

FORMAT ‘‘/disk1/backup/%U‘‘, ‘‘/disk2/backup/%U‘‘, ‘‘/disk3/backup/%U‘‘;

2.07 排除选项 exclude

configure exclude for tablespace ‘‘users‘‘;

configrue exclude clear;

2.08 备份集大小 maxsetsize

configure maxsetsize to 1G|1000M|1000000K|unlimited;

configure maxsetsize clear;

2.09 其它选项 auxiliary

CONFIGURE AUXNAME FOR DATAFILE 1 TO ‘‘/oracle/auxfiles/aux_1.f‘‘;

CONFIGURE AUXNAME FOR DATAFILE 2 TO ‘‘/oracle/auxfiles/aux_2.f‘‘;

CONFIGURE AUXNAME FOR DATAFILE 3 TO ‘‘/oracle/auxfiles/aux_3.f‘‘;

CONFIGURE AUXNAME FOR DATAFILE 4 TO ‘‘/oracle/auxfiles/aux_4.f‘‘;

CONFIGURE AUXNAME FOR DATAFILE 1 CLEAR;

CONFIGURE AUXNAME FOR DATAFILE 2 CLEAR;

CONFIGURE AUXNAME FOR DATAFILE 3 CLEAR;

CONFIGURE AUXNAME FOR DATAFILE 4 CLEAR;
