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:oracleproduct10.2.0adminorcl

机器B:
创建要恢复oracle的目录
e:oracleproduct10.2.0oradataorcl
e:oracleproduct10.2.0admin
e:oracleproduct10.2.0falsh_recovery_area
把收到的文件夹orcl放到e:oracleproduct10.2.0admin
拷贝
e:oracleproduct10.2.0adminorclpfile中的参数文件到自己真实数据库db_1database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:backORCL_2_20090414_FULL.BAK;
cmd2:
alter database mount;
cmd3:
run{
set newname for datafile 1 to E:oracleproduct10.2.0oradataorclSYSTEM01.DBF;
set newname for datafile 2 to E:oracleproduct10.2.0oradataorclUNDOTBS01.DBF;
set newname for datafile 3 to E:oracleproduct10.2.0oradataorclSYSAUX01.DBF;
set newname for datafile 4 to E:oracleproduct10.2.0oradataorclUSERS01.DBF;
set newname for datafile 5 to E:oracleproduct10.2.0oradataorclXM;
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;
