In this scenario I will duplicate database on a remote host with the same directory structure as of original database. In this example original database is dbase and the hostname of the original database is neptune while the duplicate database name will be dupbase and the hostname of the duplicate database is saturn.
The following steps is needed to perform the operation.
A)Backup the original database. Here original database is dbase on host neptune.

B)Prepare the auxiliary instance. Auxiliary instance will be created in saturn host and name of the auxiliary instance is dupbase.
i)Create pfile with parameter db_name=dupbase . If you want to rename control file set control_files parameter in pfile.
bash-3.00$ vi /oradata2/initdupbase.ora
db_name=dupbase
ii)Set the Oracle sid in saturn to dupbase.
bash-3.00$ export ORACLE_SID=dupbase
iii)Create spfile from pfile.
