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;
