> cp files /backup/
> startup
5.restore to a different location
> connect system/manager as sysdba
> startup mount
> alter database rename file ‘/disk1/../user.dbf‘ to ‘/disk2/../user.dbf‘;

>recover tablespace user_data;
>recover datafile 2;
>alter database recover datafile 2; to apply redo log files automatically
>set autorecovery on
>recover automatic datafile 4;
8.complete recovery:
–method 1(mounted databae)
>copy c:\backup\user.dbf c:\oradata\user.dbf
>startup mount
>recover datafile ‘c:\oradata\user.dbf;
>alter database open;
–method 2(opened database,initially opened,not system or rollback datafile)
>copy c:\backup\user.dbf c:\oradata\user.dbf (alter tablespace offline)
>recover datafile ‘c:\oradata\user.dbf‘ or
>recover tablespace user_data;
>alter database datafile ‘c:\oradata\user.dbf‘ online or
>alter tablespace user_data online;
–method 3(opened database,initially closed not system or rollback datafile)
>startup mount
>alter database datafile ‘c:\oradata\user.dbf‘ offline;
>alter database open
>copy c:\backup\user.dbf d:\oradata\user.dbf
>alter database rename file ‘c:\oradata\user.dbf‘ to ‘d:\oradata\user.dbf‘
>recover datafile ‘e:\oradata\user.dbf‘ or recover tablespace user_data;
>alter tablespace user_data online;
–method 4(loss of data file with no backup and have all archive log)
>alter tablespace user_data offline immediate;
>alter database create datafile ‘d:\oradata\user.dbf‘ as ‘c:\oradata\user.dbf‘‘
>recover tablespace user_data;
>alter tablespace user_data online
5.perform an open database backup
> alter tablespace user_data begin backup;
> copy files /backup/
> alter database datafile ‘/c:/../data.dbf‘ end backup;
> alter system switch logfile;
6.backup a control file
> alter database backup controlfile to ‘control1.bkp‘;
> alter database backup controlfile to trace;
7.recovery 103f(noarchivelog mode)
> shutdown abort

>alter database drop logfile group 1;
>alter database open;
or >cp c:\oradata\redo02.log‘ c:\oradata\redo01.log
>alter database clear logfile ‘c:\oradata\log01.log‘;
