一.List命令
RMAN的list命令是一种在数据库控制文件或恢复目录中查询备份的历史信息的方法。
1.列出对应物
命令:list incarnation
作用:为用户提供目标数据库的每个数据库对应物列表,可以将数据库恢复到执行最后一条resetlogs命令前的某个时间点。

可以看到数据库具有的对应物。其中(Inc关键字)是每个对应物自己的键。Status字段列,列出该对应物的状态。有旧的对应物(PARENT)、当前对应物(CURRENT)、孤立对应物(ORPHAN,在resetlogs命令之后进行恢复)。重置SCN和重置时间说明创建数据库对应物的时间(这是第一个条目的重置SCN为1的原因)。该列对用resetlog命令进行恢复有用,并容易恢复到前面的对应物。


2.列出备份
2.1概述可用的备份:
rman>List backup summary;
2.2按备份类型列出备份
rman>List backup by file;
2.3其他备份信息
rman>List backup;
2.4列出适合恢复的备份
rman>List recoverable backup of database;
2.5列出到期的备份信息
rman>List expired backup;
list expired backup of datafile 3或list expired backup of archivelog all,可获得到期的归档日志备份和控制文件/服务参数文件自动备份列表。
2.6按表空间名和数据文件号列出备份
rman>list backup of tablespace users;
rman>list backup of datafile 3;
2.7列出归档日志备份
rman>list archivelog all;
用list backup of archivelog all命令可查看更详细的归档日志备份。
2.8   列出控制文件和服务器参数文件备份
rman>list backup of controlfile;


3.列出映像副本
列出所有的映像副本使用list copy;
3.1列出数据文件副本
rman>list copy of database;
查看是否存在表空间和数据文件的数据文件副本用:list copy of tablespace users;
3.2列出归档的重做日志
rman>list copy of archivelog all;
也可以按照时间、序列或数据库scn列出特定的归档的重做日志副本。如:
rman>list copy of archivelog from sequence 35;
rman>list copy of archivelog from sequence 33 until sequence 35;
3.3列出控制文件副本
rman>list copy of controlfile;


二.Report命令
RMAN的report命令用于判断数据库的当前可恢复状态和提供数据库备份的特定信息。
1. 报告最近没有被备份的数据文件
查看最近3天没有备份过的表空间,如:
rman>report need backup days = 3;
根据需要应用的增量备份数生成报告,如:
rman>report need backup incremental = 3;
2. 报告备份冗余或恢复窗口
rman>report need backup redundancy = 2;
rman>report need backup recovery window of 2 days;
3. 报告数据文件的不可恢复操作
rman>report unrecoveable;
4. 报告数据库模式
模式指的是数据库的物理结构。模式包括数据文件名、数据文件号、为这些数据文件指派的表空间、数据文件大小、以及数据文件是否含有回滚段。
rman>report schema;
5. 报告丢弃的备份
如备份时使用了保存策略,备份有可能会被标记为丢弃状态(OBSOLETE)。此时执行report obsolete就可查看到丢弃的备份记录
