DATA GUARD IN ACTIVE PASSIVE OS CLUSTER WINDOWS

Question

Hello Gurus
I am setting up data guard in sap on windows with active passive OS clustering.
Please clear below 3 confusions.
1)I have same database name and sid of standby database as primary.Now to have different service i am just using it in setting parameters and tns_alias like
Listener file for primary and standby same as sid same
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=PROD)
(ORACLE_HOME=/oracle/product/11.2.0)
(SID_NAME=PROD)
tNSNAMES adding entry on primary as
PROD2
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=dev-db2)
(port=1521)
(connect_data=
(service_name=prod2
server=dedicated)))
tnsnames added entry on standby of primary
PROD
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=dev-db2)
(port=1521)
(connect_data=
(service_name=prod
server=dedicated)))
---->in parameter i am using service for standby as
alter system set log_archive_dest_2='service=PROD2 async valid_for=(online_logfile,primary_role) db_unique_name=prod2;
**But i have am not creating any service as such.Will THIS WORK and alright.
as i am having confusion that my SID is same so how service be differentiated.am i doing right way.
2)as my primary database having 2 node in OS cluster so like node1 having ip 192.68.2.22  node 2 ip  192.68.2.23..They are in active passive clusten.the datafiles and other oracle files can be shifted to any node as per requirement.So they are using a virtual ip 192.68.2.20.. Now i need to create standby for this primary....standby ip is 192.68.2.40
So in tnsnames i am giving all ips  the virtual ip 192.68.2.20 and host ips of both nodes on standby tnsnames and on primary adding entry of standby ip 192.68.2.40.Means i am doing entries of virtual ip and host of node1 and node2.
So i am able to ping the virtual ip from standby but not able to ping 192.68.2.22 and 192.68.2.23.
So is it fine .Would i be able to create standby database as only virtual will be needed or i am going on wrong path.
3)Can i just create the standby database by using duplicate command without taking backup in 11g.(means without physical copy of data files etc from primary to standby)
likewise
On the primary server, connect to Primary database(ORCL) as target and standby database(ORCL_DTGD) as auxiliary.
$ rman target sys/sys@ORCL auxiliary sys/sys@ORCL_DTGD
RMAN>DUPLICATE TARGET DATABASE FOR STANDBY FROM ACTIVE DATABASE DORECOVER
SPFILE SET DB_UNIQUE_NAME='ORCL_DTGD' SET LOG_ARCHIVE_DEST_2='service=ORCL LGWR SYNC REGISTER VALID_FOR=(online_logfile,primary_role)' Set STANDBY_FILE_MANAGEMENT='AUTO' SET FAL_SERVER='ORCL' SET FAL_CLIENT='ORCL_DTGD' SET CONTROL_FILES='/data/oracle/app/oracle/oradata/ORCL/control01.ctl’,'/data/oracle/app/oracle/fast_recovery_area/ORCL/control02.ctl’ NOFILENAMECHECK;
after configuring tns,listener etc
Regards
thanks for ur time..please reply as i am really looking for ur great ideas and need them.

Answer 1

For Question 1:
The SERVICE attribute, which is a mandatory attribute for a redo transport
destination, must be the first attribute specified in the attribute list. The SERVICE
attribute is used to specify the Oracle Net service name used to connect to the redo
transport destination. The service name must be resolvable through an Oracle Net
naming method to an Oracle Net connect descriptor that matches the Oracle Net
listener(s) at the redo transport destination.

For Question 2:
I would DNS if possible. If you cannot see IP's you can add them the the HOSTs file on most OS's as a work around.
Not sure what you are trying to do exactly.
For Question 3:
Yes.
Duplicate for Standby using active duplicate.
