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
