Oracle Rman 备份命令超详解释

一、list常用命令总结备忘

list incarnation;

list backup summary;

list backup of database summary;

list backup of tablespace summary;

list backup of datafile n,n summary;

list archivelog all summary;

list archivelog all;

list backup by file;

list backup;

list expired backup;

list copy;

list backup of spfile;

list backup of controlfile;

list backup datafile n,n,n;

list backup tablespace tablespace_name;

list backup of archivelog all;

list backup of archivelog from scn ...;

list backup of archivelog until scn ...;

list backup of archivelog from sequence ..;

list backup of archivelog until time 'sysdate-10';

list backup of archivelog {all, from, high, like, logseq, low, scn, sequence, time, until};

1.List 当前RMAN所备份的数据库：

RMAN> list incarnation;

1.1. list backup summary; --概述可用的备份

这个命令可以派生出很多类似命令，例如

list backup of database summary

list backup of archivelog all summary

list backup of tablespace users summary;

list backup of datafile n,n,n summary

这些命令可以让我们对已有的备份文件有一个整体，直观的了解。

1.2.list backup by file;--按照文件类型分别列出

1.3.list backup;

这个命令列出已有备份集的详细信息。

1.4.list expired backup;

列出过期的备份文件

1.5.list copy;

list copy of database;

list copy of controlfile;

list copy of tablespace users;

list copy of datafile n,n,n;

list copy of archivelog all;

list copy of archivelog from scn 10000;

list copy of archivelog until sequence 12;

2.List 相关文件的信息

list backup of {archivelog, controlfile, database, datafile, spfile, tablespace};

list backup of database; --full,incremental,tablespace,datafile

list backup of spfile;

2.2 控制文件：

list backup of controlfile;

2.3 数据文件：

list backup of datafle n,n,n,n;

2.4表空间：

2.5归档日志：

list backup of archivelog {all, from, high, like, logseq, low, scn, sequence, time, until};

list backup of archivelog all;

list backup of archivelog until time 'sysdate-1';

list backup of archivelog from sequence 10;

list backup of archivelog until sequence 10;

list backup of archivelog from scn 10000;

list backup of archivelog until scn 200000;

list archivelog from scn 1000;

list archivelog until scn 2000;

list archivelog from sequence 10;

list archivelog until sequence 12;

二、report常用命令总结备忘

report用于判断数据库当前可恢复状态、以及数据库已有备份的信息。

最常使用的是report obsolete; report schema;

report {device, need, obsolete, schema, unrecoverable}

report schema;

report obsolete;

report unrecoverable;

report need backup;

report need backup recovery window of 2 days;

2.1.report schema;

报告数据库模式

22.report obsolete;

2.3.report unrecoverable;

2.4.report need backup;

report need backup days=3;

report need backup incremental=3;

report need backup redundancy=3;

report need backup recovery window of 2 days;

三、backup常用命令总结备忘

1.设置备份标记

backup database tag='full_bak1';

注：每个标记必须唯一，相同的标记可以用于多个备份只还原最新的备份。

backup database maxsetsize=100m tag='datafile1';

RMAN-06183: datafile or datafile copy larger than MAXSETSIZE: file# 1 /data/oradata/system01.dbf

run {

allocate channel c1 type disk maxpicecsize 100m format '/data/backup/full_0_%U_%T';

backup database tag='full_0';

release channel c1;

}

Configure channel device type disk maxpiecesize 100 m;

configure channel device type disk clear;

4.备份集的保存策略
