Restore database RMAN

Question

Hi, I have done backup of my database but dont know how exactly do restore can any body help me or just give me the idea how to do that because i tried restore commands but what happen is i did backup and changed something and then run the restore commands but that change was there as well as it was done after the backup
e.g.
I have done full backup like this
set oracle_sid=%1
echo.>>FullBkup.log
echo Full database backup started at:>>FullBkup.log
date /t >>FullBkup.log
time /t >>FullBkup.log
rman target / cmdfile FullBkup.rcv log FullBkup.log append
echo.>>FullBkup.log
echo Full database backup completed at:>>FullBkup.log
date /t >>FullBkup.log
time /t >>FullBkup.log
I get following files in backup folder (BW is the name of instance)
BW_CF_FC-245465656-20060914-00
BW_DF767861_S2_P1
BW_DF767833_S3_P1
Any help really be appreciated

Thanks Daljit,
I have ran a command but get the following error
RMAN> run {
2> set until time 'sysdate-1/24';
3> restore database;
4> recover database;
5> alter database open;
6> }
executing command: SET until clause
using target database controlfile instead of recovery catalog
