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 ASM. 11.1.0.6 OEL 5 There is a good blog at http://www.colestock.com/blogs/2007/10/creating-physical-standby-using.h tml 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 "db_unique_name"="DGPHYS" 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 John +44 (0)113 223 2274 (direct) +44 (0)113 297 9797 BJSS - Platinum Sponsors of the 2008 Agile Business Conference www.agileconference.org The information included in this email and any files transmitted with it may contain information that is confidential and it must not be used by, or its contents or attachments copied or disclosed, to persons other than the intended addressee.
