Enable Archivelog Mode On 2 Node RAC DATABASE

Question

hi,
We are having 2 Node Rac 10g Database Installed on Windows.
Currently the Database is in Non Archivelog Mode.
I want to convert it to Archivelog Mode.
I come to know the steps to convert cluster database to Archivelog mode.
i.e.
set archive parameters like Disk Location and Archivelog File format.
then Convert the database in Exclusive Mode
ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;
then
C:\> srvctl stop database -d <Global_DB_SID>
then enable Archivelog Mode.
SQL> STARTUP MOUNT;
SQL> ARCHIVE LOG START;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE SET cluster_database=TRUE SCOPE=spfile;
SQL> SHUTDOWN IMMEDIATE
C:\> srvctl start database -d <Global_DB_SID>
But I am confuse with Do i need to RUN this commands in both the nodes seperatly or only on any one node.
Please Reply,

Node 1: OSERP1
Log on to OSERP1 Server
C:\> sqlplus sys/oracle@racdb2 as sysdba
SQL> ALTER SYSTEM SET log_archive_format='arch_%t_%s.arc' SCOPE=spfile ; -- this needs to be database wide
SQL > ALTER SYSTEM SET log_archive_dest_1='location=\\OSERP1\archive$\ERP1 ' SCOPE=spfile sid ='ERP1'; -- required quotes added
-- not required
SQL> ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;
not required to connect to other node
-- not required
SQL> ALTER SYSTEM SET log_archive_format='arch_%t_%s.arc' SCOPE=spfile sid =ERP2;
SQL > ALTER SYSTEM SET log_archive_dest_1='location=\\OSERP2\archive$\ERP2 ' SCOPE=spfile sid ='ERP2'; -- quotes added
-- not required, and database wide setting
SQL> ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;
Then following commands will be run connecting any of the instance
-- database has to be stopped first, if you stick to switching it to a non-cluster database
C:\> set ORACLE_SID=<local_instance_id>
C:\> sqlplus / as sysdba
SQL> STARTUP MOUNT;
-- wrong sequence of commands
SQL> ARCHIVE LOG START;
SQL> ALTER DATABASE ARCHIVELOG;
-- not required (see previous steps)
SQL> ALTER DATABASE SET cluster_database=TRUE SCOPE=spfile;
SQL> SHUTDOWN IMMEDIATE;
6. Start the cluster database.
C:\> srvctl start database -d <Global_DB_SID>
-- There is no such thing as a <Global_DB_SID>. There is a database name.
Please note your tnsnames.ora, in a standard install, needs to have the following service names.
ERP
ERP1
ERP2
I'm not sure why you have the non-standard service_name racdb2.
Somehow it looks like you both don't understand the RAC concept, and didn't understand my answer. I had to correct several things I already corrected in my previous response. I'm not sure why I'm not getting through.
