oracle 之rman备份数据库(File system)
1、备份整个数据库
backup database format '/home/oracle/backup/rmandatabase_%U.bak';
2、备份表空间
backup tablespace abc format '/home/oracle/backuprmantablespace_%U.bak';
3、备份数据文件
1）backup datafile 5 format '/home/oracle/backup/rmandatafile_%U.bak';
2）backup datafile '/u01/app/oracle/oradata/ygzhou/ygzhou01.dbf' format '/home/oracle/backup/rmanddatafile_%U.bak';
4、备份控制文件
backup current controlfile format '/home/oracle/backup/rmancontrolfile_%U.ctl';
5、备份数据文件同时备份控制文件
backup datafile 5 format '/home/oracle/backup/rmandatafile_controlfile_%U.bak' include current controlfile;
6、备份spfile文件
backup spfile format '/home/oracle/backup/rmanspfile_%U.sp';
7、备份日志文件
backup archivelog sequence between 38 and 41 format '/home/oracle/backup/rmanarchivelog_%U.log’ delete all input;（可选项，表示备份日志文件后，删除原来日志文件）
8、备份数据库和日志文件
backup database plus archivelog format '/home/oracle/backup/rmandatafile_archivelog_%U.bak' delete all input;
9、copy功能（相当于用户管理备份）
backup as copy database format '/home/oracle/backup/rmandatabase_%U.cy';
copy datafile 5 to '/home/oracle/backup/rmandatafile_%U.cy';
【NOTE】：
-
backup as copy可以备份整个数据库
-
copy只能备份current controlfile、datafile、tablespace等，这个数据库不支持
oracle 之rman备份数据库(ASM)
发现
11.2.0.2的物理备库无法删除过期日志，删除脚本如下[oracle@]$ more /home/oracle/monitor/deletearchivelog.sh
. /home/oracle/.bash_profile
rman target / @/home/oracle/monitor/deletearchivelog > /home/oracle/monitor/deletearchivelog.log
[oracle@report-db01 ~]$ more /home/oracle/monitor/deletearchivelog
crosscheck archivelog all;
delete noprompt force archivelog until time 'sysdate-1/4';
delete noprompt force archivelog all;
其中报错日志为
RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process
此为11g的bug，需要在delete后加上force关键字，metalink上有记载
Applies To:11gR1-11gR2
RMAN is unable to delete archive logs from database even though they are not needed by CAPTURE process anymore.
Changes
Cause
In 11g, RMAN looks at MIN_REQUIRED_CAPTURE_CHANGE# in v$database and not at DBA_CAPTURE. By default this value is updated every 6 hours. So by default the value in v$database will be six hours behind the current value.
Solution
Since changing frequency of update to MIN_REQUIRED_CAPTURE_CHANGE# in v$database can not be controlled, following workaround can be used:
Archive log which are not needed by capture process can be deleted using:
delete noprompt force archivelog all completed before 'sysdate-10/1440';
