Problem While Creating Physical Standby Using RMAN

Question

Hi Guru's
May be this incidence you all face while creating physical standby DB. I try to create Physical standby database Using RMAN Duplicate Command from one server
(pri machine) to Standby Machine.
The steps i followed to create the above are as follows:
Step 1:- Enable Forced Logging
SQL> ALTER DATABASE FORCE LOGGING;
Step 2:- Configure a Standby Redo Log
SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 10
  2> ('/oracle/dbs/log1c.rdo','/oracle/dbs/log2c.rdo') SIZE 500M;
Step 3:- Set Primary Database Initialization Parameters
SQL> create pfile='?/dbs/pfileorcl.ora' from spfile;
Edit the pfile to add the standby parameters, here shown:
db_unique_name='orcl'
LOG_ARCHIVE_CONFIG='DG_CONFIG=(orcl,orcldr)'
LOG_ARCHIVE_DEST_2='SERVICE=orcldr LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcldr'
*.fal_server=orcldr
*.fal_client=orcl
*.standby_file_management=auto
Step 4:- Enable Archiving
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP MOUNT;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE OPEN;
Step 5:- Setup tnsnames for standby database
This should be done on primary database by altering tnsnames.ora or using NetCA command, and create it by the name orcldr
orcldr =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby-svr)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcldr)
Step 6:- Backup database and copy it to standby
This backup script should be run on primary and copied to standby on the same mount point, running this scripts using RMAN, all files under /rman_backup should be copied to /rman_backup on standby server.
$rman target /
RMAN> run
allocate channel c1 type disk;
allocate channel c2 type disk;
backup database format '/rman_backup/%U';
backup archivelog all format '/rman_backup /%U';
backup current controlfile for standby format '/rman_backup/%U';
Step 7:- Standby Database Steps
Installing Oracle Software
This should be same release and patchset with exactly same ORACLE_HOME mount point.
Setting Up listener
Create and start a listener on standby database using NetCA, or creating listener.ora in $ORACLE_HOME/network/admin
LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = standby-svr)(PORT = 1521))
Step 8:- Set Standby Database Initialization Parameters
Copying the pfile created in primary database and renames it to initorcldr.ora, and changes these parameters:
db_unique_name='orcldr'
LOG_ARCHIVE_CONFIG='DG_CONFIG=(orcldr,orcl)'
LOG_ARCHIVE_DEST_2='SERVICE=orcl LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcl'
*.fal_server=orcl
*.fal_client=orcldr
*.LOG_ARCHIVE_DEST_STATE_2='ENABLE'
Step 9:- Setup tnsnames for primary database
This should be done on standby database by altering tnsnames.ora or using NetCA command, and create it by the name orcl
orcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = primary-svr)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
Step 10:- Copy a Password File
A password file must be created on the Primary and copied over to the Standby site. The sys password must be identical on both sites. Copy orapworcl to $ORACLE_HOME/dbs and rename file to orapworcldr
Step 11:- Create mount points for Oracle
Mount point should be created on standby server with the same convention used in primary, this includes the location for controlfiles, redo logs, datafiles, archive log destination and alert logs.
$ mkdir -p /u01/app/oracle/oradata/orcl/
$ mkdir -p /u01/app/oracle/flash_recovery_area/
$ mkdir -p /u01/app/oracle/admin/orcl/adump
$ mkdir -p /u01/app/oracle/admin/orcl/bdump
$ mkdir -p /u01/app/oracle/admin/orcl/cdump
$ mkdir -p /u01/app/oracle/admin/orcl/udump
Step 12:- Use RMAN to restore backup and setup standby
Connect to RMAN and execute the following command to create standby database, this should be performed on standby server after copying backup and setting tnsnames.
$ export ORACLE_SID=orcldr
$ rman target sys/tiger@orcl auxiliary sys/tiger@orcldr
RMAN> duplicate target database for standby dorecover;
Here i am getting problem as :
While trying to connect to traget database and auxiliary database i notice that when RMAN is connect to both databases it shows
orcl ( DBID xyz)
orcl (not mounted)
Here in my view the second database must be standby database name or auxiiary db name is standby db name which in my case is orcldr
after this issue i am facing the second issues as :
in command
duplicate target database for standby dorecover;
After modifying the command to
RMAN> duplicate target database to "standby";
rman-05520 database name mismatch
Can u please let me know where i am mistaking

Answer 1

ok for pri:
db_name=orcl
db_unique_name=orcl
for standby:
db_name=orcl 
db_unique_name=sbyorcl ( i change orcldr to sbyorcl later)for new testing
but now what i am getting on
  Verify connectivity
