At the beginning we have to prepare parameter file for the new instance
*._catalog_foreign_restore=FALSE *.audit_trail='db' *.compatible='188.8.131.52.0' *.db_block_size=8192 *.db_create_file_dest='/u01/app/oracle/oradata' *.db_domain='' *.db_name='skiper' *.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area' *.db_recovery_file_dest_size=4560m *.diagnostic_dest='/u01/app/oracle' *.dispatchers='(PROTOCOL=TCP) (SERVICE=skiperXDB)' *.enable_pluggable_database=true *.open_cursors=300 *.pga_aggregate_target=512m *.processes=300 *.remote_login_passwordfile='EXCLUSIVE' *.sga_target=1g *.undo_tablespace=‚UNDOTBS1'
Start the instance in nomount
[oracle@rico dbs]$ export ORACLE_SID=skiper [oracle@rico dbs]$ sqlplus / as sysdba SQL*Plus: Release 184.108.40.206.0 Production on Mon May 25 14:32:46 2015 Copyright (c) 1982, 2014, Oracle.

Since I want to duplicate the database in active mode I will register it in LISTENER. To achieve this I have to add the following lines to the listener.ora
SID_LIST_LISTENER= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=skiper) (SID_NAME=skiper) (ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1) ) )
Now we can perform active database duplication with only one pluggable database
oracle@rico dbs]$ rman target sys/Oracle123@localhost:1521/rico auxiliary sys/Oracle123@localhost:1521/skiper Recovery Manager: Release 220.127.116.11.0 - Production on Mon May 25 14:44:41 2015 Copyright (c) 1982, 2014, Oracle and/or its affiliates. All rights reserved. connected to target database: RICO (DBID=645399623) connected to auxiliary database: SKIPER (not mounted) RMAN> duplicate target database to skiper pluggable database ricopdb from active database using compressed backupset; (output removed for clarity)
Now we have to close the pluggable database and unplug it
SQL> alter pluggable database ricopdb close; Pluggable database altered. SQL> alter pluggable database ricopdb unplug into '/home/oracle/ricopdb.xml'; Pluggable database altered.
Now we can plug the database in our original container
SQL> create pluggable database ricotestpdb as clone using '/home/oracle/ricopdb.xml' 2 ; Pluggable database created. SQL> select con_id, name from v$pdbs; CON_ID NAME ---------- ------------------------------ 2 PDB$SEED 3 RICOPDB 4 RICOTESTPDB
If you don’t want to copy datafiles to thair new location, you can use the following statement:
SQL> create pluggable database ricotest2pdb as clone using '/home/oracle/ricopdb.xml' nocopy; Pluggable database created.
