Duplicate Database Without Target Connection or Catalog Connection

There are many techniques for database duplication. There's an earlier post which lists step for duplicating RAC database to a single instance using active database. This post list the steps for duplicating a source database without connecting to the target nor rman catalog. For more information on this refer Backup-Based Duplication Without a Target and a Recovery Catalog Connection in the Oracle documentation
Since no connectivity from source database is required for this technique of duplicating , there's no need to create static listener configuration in the duplicate host nor adding tns entry to the source tnsnames.ora file.
. But a default listener is needed for the database.
The source database is called ent11g2 and the duplicated database will be named dupdb.
1. On the source database create a full database backup and copy the backup to the host where duplicate database will be created. The backup location need not be same as in the source location. For this post the backups will be copied to location "/home/oracle/backup" in the host used for the duplicate database. The source database is using OMF names and using recovery destination for the backups. If auto backup of control file is enabled copy the auto backup control file and the backup sets to the host where the duplicate database will be created.
cd /data/flash_recovery/ENT11G2
ls
archivelog  autobackup  backupset  controlfile  flashback  onlinelog
cd autobackup/2013_10_01/
ls
o1_mf_s_827667431_94o9gqww_.bkp  <==== auto backup of control file
scp -C o1_mf_s_827667431_94o9gqww_.bkp 192.168.0.99:/home/oracle/backup
o1_mf_s_827667431_94o9gqww_.bkp         100%   10MB  10.2MB/s
cd backupset/2013_10_01
$ scp -C * 192.168.0.99:/home/oracle/backup
o1_mf_annnn_TAG20131001T113643_94o9fw2g_.bkp                  100%   14MB   6.9MB/s   00:02
o1_mf_annnn_TAG20131001T113710_94o9gpnp_.bkp                  100%   11KB  10.5KB/s   00:00
o1_mf_nnndf_TAG20131001T113645_94o9fxjn_.bkp                  100% 2170MB  13.2MB/s   02:45
That's the only time the source database is involved. Rest of the steps happen in the host used for the duplication.
2. Create password file for the duplicate database. This is not a must for the duplication (this method of duplication will work even without a password file) but may be required later on when the duplicate database is in use.
orapwd file=orapwdupdb password=password ignorecase=y
3. Create the directory for the audit files. Without this duplication would fail with audit trail set to OS.
mkdir -p /opt/app/oracle/admin/dupdb/adump
4. Create an init file with the db_name parameter set in it. 
cat initdupdb.ora
db_name='dupdb'
5. Start the duplicate database in the nomount mode.
export ORACLE_SID=dupdb
SQL> startup nomount;
6. Connect to the duplicate database using an rman auxiliary connection 
[oracle@hpc5 dbs]$ rman auxiliary /

connected to auxiliary database: DUPDB (not mounted)
and run the duplicate command
DUPLICATE TARGET DATABASE
TO dupdb
SPFILE PARAMETER_VALUE_CONVERT 'ent11g2', 'dupdb', '/data/oradata', '/opt/app/oracle/oradata', 
'/data/flash_recovery','/opt/app/oracle/flash_recovery_area','ENT11G2','DUPDB'
set db_create_file_dest='/opt/app/oracle/oradata'
set db_recovery_file_dest='/opt/app/oracle/flash_recovery_area'
BACKUP LOCATION '/home/oracle/backup';
When data files use OMF names rather than using *file_name_convert parameter duplication must use create_file_dest. Refer Specifying OMF or ASM Alternative Names for Duplicate Database Files section on Oracle documentation.




Full output of the duplicate command is given below.
RMAN> DUPLICATE TARGET DATABASE
2> TO dupdb
3> SPFILE PARAMETER_VALUE_CONVERT 'ent11g2', 'dupdb', '/data/oradata', '/opt/app/oracle/oradata', '/data/flash_recovery','/opt/app/oracle/flash_recovery_area','ENT11G2','DUPDB'

5> set db_recovery_file_dest='/opt/app/oracle/flash_recovery_area'
6> BACKUP LOCATION '/home/oracle/backup';
