Creating a duplicated database from active database

Question

I'm having problem trying to duplicate a database from a target database (PROD) to the auxiliary one (AUX).
This is what I've configured:
listener.ora
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = PROD)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1/)
      (SID_NAME = PROD)
    (SID_DESC =
      (GLOBAL_DBNAME = AUX)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1/)
      (SID_NAME = AUX)
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = my_ip)(PORT = 1521))
ADR_BASE_LISTENER = /u01/app/oracletnsnames.ora
AUX =
  (DESCRIPTION =
    (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = my_ip)(PORT = 1521)))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = AUX)
PROD =
  (DESCRIPTION =
    (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = my_ip)(PORT = 1521)))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = PROD)
  )/u01/app/oracle/product/11.2.0/db_1/dbs/initAUX.ora
db_name='AUX'
cp /u01/app/oracle/product/11.2.0/db_1/dbs/orapwPROD /u01/app/oracle/product/11.2.0/db_1/dbs/orapwAUX- Started PROD database (open and in archive log mode)
- Started AUX database (in nomount mode and usinf pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initAUX.ora')
But when I issue the following command I get connected to auxiliary database (not started) :
rman target sys/oracle@PROD auxiliary sys/oracle@AUX
connected to target database: PROD (DBID=196032563)
connected to auxiliary database (not started)And executing the duplicate command it returns:
RMAN> duplicate target database to AUX from active database spfile parameter_value_convert '/DATA/PROD/','+DG_DATA_AUX' set db_create_file_dest='+DG_DATA_AUX';

The command completed successfullyI have already created a duplicated database from a backup of the target one and the configuration was quite the same: the differences are that using active database duplication I needed to use orapw files (and they need to have the same password) and that I needed to connect using Oracle Net service name to connect to the auxiliary instance.. otherwise I got:
export ORACLE_SID=AUX
rman target sys/oracle@PROD auxiliary sys/oracle
connected to target database: PROD (DBID=196032563)
connected to auxiliary database: AUX (not mounted)
RMAN> duplicate target database to AUX from active database spfile parameter_value_convert '/DATA/PROD/','+DG_DATA_AUX' set db_create_file_dest='+DG_DATA_AUX';

Answer 1

Thanks for your support. My instance was and is still in nomount mode. But I'm not able to connect this instance as auxiliary and in the right expected mode:
connected to auxiliary database: AUX (not mounted)
[oracle@my_ip oracle]$ env|grep SID      
ORACLE_SID=AUX
[oracle@my_ip oracle]$ sqlplus / as sysdba
