 20数据回来了，但是由于归档和redo log丢了，丢失一部分数据。 
 21
 22  
 23情况二 数据库崩溃，但是还剩下归档和redo log是好的。 
 24

 26启动归档   
 27SQL&gt;alter database archivelog;

 39重启数据库，归档就会自动启动。 
 40
 41启动自动备份控制文件 
 42
 43RMAN&gt; configure controlfile autobackup on; 
 44
 45new RMAN configuration parameters:   
 46CONFIGURE CONTROLFILE AUTOBACKUP ON;   
 47new RMAN configuration parameters are successfully stored 
 48
 49配置RMAN的格式和存储位置。   
 50RMAN&gt; configure channel device type disk format 'F:\backup\%U'; 
 51
 52new RMAN configuration parameters:   
 53CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'F:\backup\%U';   
 54new RMAN configuration parameters are successfully stored 
 55
 56查看数据文件的位置   
 57SQL&gt; select name from v$datafile; 
 58
 59  
 60确定原控制文件的路径   
 61SQL&gt; select name from v$controlfile; 
 62
 63查看log位置 
 64
 65SQL&gt;select name from V$ARCHIVED_LOG； 
 66
 67查看log的信息   
 68SQL&gt;select * from v$log_history; 
 69
 70插入数据   
 71SQL&gt; select * from sss;

 94用DBCA删除数据库，删除相关的数据文件，保留redo log和归档日志。 
 95
 96再用DBCA重建一个SID一样的数据库。 
 97
 98RMAN&gt;startup 
 99
100配置RMAN   
101RMAN&gt; configure channel device type disk format 'F:\backup\%U'; //注意和原来的格式一样。 
102
103new RMAN configuration parameters:   
104CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'F:\backup\%U';   
105new RMAN configuration parameters are successfully stored 
106
107  
108RMAN&gt;startup nomount   
109RMAN&gt;restore controlfile to '/opt/oracle/oradata/control01.ctl' from autobackup;   
110再copy几份和原来一样的路径文件名。
