急(在线)! recovery的问题

[kevinwhz]

我已用下面backup,但是不知如何recover?请大侠指教!(recover的用法及注意事项)

spool C:\ORACLE\ORADATA\LOG\backup.MYDB.030707.log
alter tablespace SYSTEM begin backup;
host copy C:\ORACLE\ORADATA\MYDB\SYSTEM01.DBF C:\oracle\oradata\MyDB\BACKUP\backup\
alter tablespace SYSTEM end backup;
alter tablespace RBS begin backup;
host copy C:\ORACLE\ORADATA\MYDB\RBS01.DBF C:\oracle\oradata\MyDB\BACKUP\backup\
alter tablespace RBS end backup;
alter tablespace USERS begin backup;
host copy C:\ORACLE\ORADATA\MYDB\USERS01.DBF C:\oracle\oradata\MyDB\BACKUP\backup\
alter tablespace USERS end backup;
alter tablespace TEMP begin backup;
host copy C:\ORACLE\ORADATA\MYDB\TEMP01.DBF C:\oracle\oradata\MyDB\BACKUP\backup\
alter tablespace TEMP end backup;
alter tablespace TOOLS begin backup;
host copy C:\ORACLE\ORADATA\MYDB\TOOLS01.DBF C:\oracle\oradata\MyDB\BACKUP\backup\
alter tablespace TOOLS end backup;
alter tablespace INDX begin backup;
host copy C:\ORACLE\ORADATA\MYDB\INDX01.DBF C:\oracle\oradata\MyDB\BACKUP\backup\
alter tablespace INDX end backup;
alter database backup controlfile to trace;
alter database backup controlfile to 'C:\oracle\oradata\MyDB\BACKUP\backup\control.MYDB.0307071233';
alter system switch logfile;
spool off
