Default Backup Location for RMAN (urgent)

Hi

I am in learning phase of rman and practising from Documentation. I have just issued following command

RMAN > run {
allocate channel c1 type disk;
backup tablespace system;
}

In the result it is onl showing me the input parameter file but how do I know that where backed up dbf is stored. I can see that there is a file got created in ORACLE_HOME\database directory ... But is it the backed up tablespace? How can I change the backup location?

Amol

Usually rman generates unique name for backup file and save it in 'database' ('dbs') directory, you can specify directory and file name using 'format' clause

run {
allocate channel ch1 type disk;
set maxcorrupt for datafile 1,2,3,4,5,6,7,8,9,10,11 to 0;
backup
incremental level=0
check logical
format='/oracle/oradata/backup/rman/demo/0.%t.%d.%s.%p'
database;
}
