RMAN multiple channel is not working

 We have 9i 9.2.0.7 database and trying to do simple database backup with 3 channel. It seems it does recognize all 3 channels but only uses 1 channel to backup the database.
This is windows env.

Here is rman script.

CONFIGURE DEVICE TYPE DISK PARALLELISM 3;
run
  {
  ALLOCATE CHANNEL 'C1' DEVICE TYPE DISK FORMAT 'U:\oraback\RMSWWP1\%d_%U';
  ALLOCATE CHANNEL 'C2' DEVICE TYPE DISK FORMAT 'V:\oraback\RMSWWP1\%d_%U';
  ALLOCATE CHANNEL 'C3' DEVICE TYPE DISK FORMAT 'T:\oraback\RMSWWP1\%d_%U';
  BACKUP Database;
   }


exit;
Any ideas?

Howdy, Stranger!
