--For a cold backup
--Need to know which files to backup:
Select name from v$datafile;
Select name from v$controlfile;
Select member from v$logfile;

Shutdown immediate;
go to OS and copy the files
Startup;

and you are done.

There are methods to back up the database

1)HOT BACKUP
if you are using archive mode (hot backup)than

c:>svrmgrl
svrmgrl>connect sys/sys as sysdba
svrmgrl>alter tablespace <<tname>> begin backup;
svrmgrl>host
use os copy command to copy the datafiles that belongs to that tablespace
c:>copy c:oracleoradatasunilsunilwork.dbf d:backup

c:>exit
svrmgrl>alter tablespace <<tname>> end backup;

repeat these steps to copy all the tablespace of db

then
copy controlfile, archive log by using just os copy command.

2) COLD BACKUP

shutdown the database
backup datafiles, control file, redo log, using os command

fine, that you have taken a hot back up.
you got .dbf files in your back.
suddenly the database is crashed and you need to put that .dbf file into another database, what would you do now?
