change RMAN backup destination

This is supposed to be easy but I can't find an answer...I've been trying to find out how to change the backup destination in RMAN when I back up (not copy) the whole DB or a tablespace, eg.:

run {
allocate channel c1 type disk;
backup database;
}

By default, on Win2k, the backup sets go to DATABASE folder under ORACLE_HOME. How can change it to have it backup to a different location? I don't think "backup database" has an option to specify destination folder.

Thanks,

Look for FORMAT command in RMAN documents.

Hi,
user the CONFIGURE command to configure default location for the disk device type:

CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/backup/ora_df%t_s%s_s%p';

Cheers.
