backup and restore

I have a database named orcl

I backup the data using rman ...

the backup is in this locationn
[oracle@wtu flash_recovery_area]$ cd orcl/
[oracle@wtu orcl]$ ls
control02.ctl
[oracle@wtu orcl]$ cd ..
[oracle@wtu flash_recovery_area]$ cd ORCL/
[oracle@wtu ORCL]$ ls
archivelog  autobackup  backupset  flashback  onlinelog
[oracle@wtu ORCL]$ cd backupset/
[oracle@wtu backupset]$ ls
2012_10_17  2012_10_29  2012_12_31
[oracle@wtu backupset]$ cd 2012_12_31/
[oracle@wtu 2012_12_31]$ ls
o1_mf_annnn_TAG20121231T022129_8g2ssc7g_.bkp
o1_mf_annnn_TAG20121231T022442_8g2szbtp_.bkp
o1_mf_nnndf_TAG20121231T022236_8g2svf3z_.bkp

and then I deleted the

[oracle@wtu oradata]$ cd orcl/
[oracle@wtu orcl]$ ls
control01.ctl  redo01.log  redo03.log    system01.dbf  undotbs01.dbf
example01.dbf  redo02.log  sysaux01.dbf  temp01.dbf    users01.dbf
[oracle@wtu orcl]$ rm -rf *



Then I tried to connect rman to restore and recovery..

Meanwhile i shutdown the database....
SQL> shutdown immediate

ORA-00202: control file: '/u01/app/oracle/oradata/orcl/control01.ctl'

Then I tried to connect rman for restore and recovery..
