RE: standby database from a RAC cluster with ASM to a single-instance server using filesystem storage not ASM.
Date: Wed, 23 Jul 2008 10:57:44 -0400
I would pick and choose from two different technet articles (from the Maximum Availability Architecture set).
aa.pdf> Guard 11g Installation and Configuration Best Practices on Oracle RAC http://www.oracle.com/technology/deploy/availability/pdf/dataguard11g_rac_ma a.pdf
arySingleInstancePhysicalStandby.pdf> g Setup Guide: Creating a Single Instance Physical Standby Database for a RAC Primary Database
In 11g you can have RMAN create the standby control file, password file, spfile for you. The spfile isn't correct, so the suggestion is to start with a simple, dummy init.ora for the standby, have RMAN pass some init parameters over during the copy, then create a pfile from the standby spfile, shutdown, edit the pfile, restart the standby. I would think you should be able to take care of the cluster problems this way.
Hope this helps. (I am just finishing a RAC to RAC (2 node to 1 node)) install. I haven't tried a non-clustered physical standby.

Subject: standby database from a RAC cluster with ASM to a single-instance server using filesystem storage not ASM.
Does anybody have any links on how to create a standby database from a RAC
cluster with ASM to a single-instance server using filesystem storage not
220.127.116.11 OEL 5
There is a good blog at
I have followed it but it gets the controlfile down and then creates an spfile from the controlfile but that contains all the RAC parameters.
I am using the following RMAN command
DUPLICATE TARGET DATABASE FOR STANDBY DORECOVER DB_FILE_NAME_CONVERT=('+DATA/','/export2/oradata/DGPHYS/')
SPFILE PARAMETER_VALUE_CONVERT '+DATA','/stdby'
SET SERVICE_NAMES 'DGPHYS.bjss.co.uk'
SET log_file_name_convert '+DATA/','/export2/oradata/DGPHYS/';
SET cluster_database=false -- to overwrite the RAC components
Set cluster database_instances=0 - tried 1 as well
This works OK and creates an spfile but will not start the databse up from the spfile because
RMAN-01008: the bad identifier was: cluster_database_instances
RMAN-01007: at line 1 column 5 file: standard input
If I take out the line cluster_database_instances it fails anyway as the spfile has been built for a RAC config
Any pointers or help appreciated
