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,
