>>dont want rman to backup controlfile and spfile auto
Do you have one valid reason for not wanting to do that?

Don't backup datafile#1 and your controlfile and spfile won't be backed up, although I don't see why you don't want to back up your controlfile and spfile

COuld you explain how would that happen?
Espcially when the OP is issuing a "backup database"

I mean out of say 100 files, if you back up 99 files, without including data file #1, then you can get away without backing up your spfile and controlfile.
You questioned the OP's reason for not wanting to back up the spfile and contriolfile, I did the same, but at the same time I gave him something to think about and work upon.

How about

CONFIGURE CONTROLFILE AUTOBACKUP OFF;

If CONFIGURE CONTROLFILE AUTOBACKUP is ON (by default it is OFF), then RMAN automatically backs up the control file and the current server parameter file after every BACKUP or COPY command issued at the RMAN prompt.

Clarified from RMAN reference:

configure controlfile autobackup off:
"Disables the autobackup feature (default). Note that when this command is OFF, any BACKUP command that includes datafile 1 (including BACKUP DATABASE) automatically includes the current control file and server parameter file in the backup set. Otherwise, RMAN does not include these files."

Supports what was posted by saibal

Thanks

>> CONFIGURE CONTROLFILE AUTOBACKUP OFF;
>> Clarified from RMAN reference:

Did you read it in entirety?
CONTROLFILE AUTOBACKUP has nothing to do with this.
If it is ON, RMAN writes the control file and server parameter file to a separate autobackup piece.
If it is OFF,RMAN does not create a separate autobackup piece containing the control file and server parameter file. Instead
RMAN automatically includes the current control file and server parameter file in the datafile backup set

True, and you can also force RMAN to put the control file in the backup set of the database by using the include current controlfile clause in the backup database command. Of course, this is assuming you are not backing up datafile#1

Can you kindly elaborate on what you are trying to prove/disprove?
I see the controlfile and spfile being backed up when you are not backing up datafile#1. This can happen when you have autobackup switched on.
