用备份控制文件的恢复

用备份控制文件的恢复,控制文件中不包含数据文件,但联机日志中有
           alter database backup controlfile to ‘D:\control.ctl‘;
           create tablespace tp1 datafile ‘D:/tp1.dbf‘ size 10M;
           create table t1(id int,name varchar2(10)) tablespace tp1;
           insert into t1 values(1,‘pl1‘);
           commit;

停服务==>services.msc==>停oracle进程
           rm -rf control*
           shutdown abort;
           拷贝 D:\control.ctl  D:\app\administrator\oradata\orcl\control01.ctl
           startup mount;
           select file#,checkpoint_change# from v$datafile;
           select file#,checkpoint_change# from v$datafile_header;
           alter database open; //提示控制文件旧了
           recover database using backup controlfile;

select * from v$log 找current的log

输入D:\oradata\orcl\redo02.log  --状态是current

提示有一个文件不识别

select file#,name from v$datafile;

alter database rename file‘D:\app/administrator\product\11.2.0\dbhome_1\database\UNNAMED00005‘ to ‘D:\tp1.dbf‘;

recover database using backup controlfile;
          输入:/oradata/orcl/redo02.log  --一select * from v$log;
          alter database open resetlogs;
