机器a:
select instance_name from v$instance;
select name from v$database;
select name from v$datafile;
查询日志模式：
archive log list;
shutdown immediate;
startup mount;
把日志改为归档模式：
alter database archivelog;
alter database open;
alter system archive log current;
select name from v$archived_log;
打开控制文件跟踪：
alter database backup controlfile to trace;
查看跟踪文件位置：
show parameter user_dump_dest
cmd：
set oracle_sid=orcl
rman target sys/abc
host “md c:\back”;
run
{
backup database;
format ‘c:\back\%d_%s_%t_full.bak’;
}
select file#,name from v$datafile;
传送以下文件到机器b:
c:\back
d:\oracle\product\10.2.0\admin\orcl
create controlfile set database “orcl” resetlogs archivelog
maxlogfiles 16
maxlogmembers 3
maxdatafiles 100
maxinstances 8
maxloghistory 292

机器b:
创建要恢复oracle的目录
e:\oracle\product\10.2.0\oradata\orcl
e:\oracle\product\10.2.0\admin
e:\oracle\product\10.2.0\falsh_recovery_area
把收到的文件夹orcl放到e:\oracle\product\10.2.0\admin
拷贝
e:\oracle\product\10.2.0\admin\orcl\pfile中的参数文件到自己真实数据库db_1\database文件夹中，并改名为initorcl.ora
打开initorcl.ora
把里面的路径改为真实oracle数据库的位置
d:\替换为e:\
cmd1：
set oracle_sid=orcl
oracle orcl
等到提示ctrl+c
cmd2：
set oracle_sid=orcl
sqlplus / as sysdba
startup nomount;
cmd3:
set oracle_sid=orcl
rman target sys/abc
restore controlfile from ‘c:\back\orcl_2_20090414_full.bak’;
cmd2:
alter database mount;
cmd3:
run{
set newname for datafile 1 to ‘e:\oracle\product\10.2.0\oradata\orcl\system01.dbf’;
set newname for datafile 2 to ‘e:\oracle\product\10.2.0\oradata\orcl\undotbs01.dbf’;
set newname for datafile 3 to ‘e:\oracle\product\10.2.0\oradata\orcl\sysaux01.dbf’;
set newname for datafile 4 to ‘e:\oracle\product\10.2.0\oradata\orcl\users01.dbf’;
set newname for datafile 5 to ‘e:\oracle\product\10.2.0\oradata\orcl\xm’;
restore database;
switch datafile all;
}
cmd2:
select name from v$database;
shutdown immediate;
startup mount;
alter database backup controlfile to trace;
找到跟踪文件：
重做控制文件：把里面的路径改为正确路径：
d:\改为 e:\
shutdown immediate;
startup nomount;
执行生成控制文件的语句;执行钱必须先删除.ctl的文件
alter database open resetlogs;
select name from v$database;
select member from v$logfile;
