1、添加redo组及成员

alter database add logfile  group 8 'E:\ORACLE\ORADATA\ORCL\REDO08.log' size 200M;
alter database add logfile member 'E:\ORACLE\ORADATA\ORCL\REDO081.log'  to group 8;

2、查看无法归档redo状态

select GROUP#  ,BYTES/1024/1024 size_M,STATUS,ARCHIVED from v$log;
         GROUP#    SIZE_M STATUS          ARC                                                                          
          4        200 INACTIVE      YES                                      
          5        200 INACTIVE      YES                                      
          6        200 CURRENT       YES 
          7        200 INACTIVE      NO
          8        200 UNUSED        NO
    SQL> select member from v$logfile;

E:\ORACLE\ORADATA\ORCL\REDO10.LOG
E:\ORACLE\ORADATA\REDO\REDO001.LOG
E:\ORACLE\ORADATA\REDO\REDO03.LOG
E:\ORACLE\ORADATA\REDO\REDO003.LOG

3、清理redo

alter database clear unarchived logfile group 7;

4、redo 删除 

alter database drop logfile group 7;
