Moving RAC/ASM to single-node non-rac SET NEWNAME not working

Question

Good morning,
I'm trying to restore a rac/asm database to a non-rac environment to simulate disaster recovery under worst-case circumstances.
Here is as faras I have been able to get
1) Restored pfile
2) modified pfile to remove references to RAC settings (note, did not set db_file_create_dest, db_file_name_convert, etc)
3) Restored controlfile successfully
4) Mounted database
At this time I run the following rman script which covers all temp and datafiles (there's some skipped numbers where datafiles have been removed previously)
run {
set until time "to_date('2009/11/29 03:00:00','YYYY/MM/DD HH24:MI:SS')";

I noticed that it's trying to create the datafile. Shouldn't it be giving me a "Restoring datafiles from backup piece" clause? Also it appears to be trying to recreate the datafiles in their old location. Any thoughts on how to get around this.
Using the db_file_name_convert does allow me to restore files to the filesystem, but they use names such as "omf_*" and I'm not sure if it's converting the files properly from ASM format.
Thanks!

Hi,
I assume your problem is either in your pfile ( but you indicate you have removed all RAC settings), or in your control file.
I would recommend to remove the control files and create them later as soon as the datafiles have been restored, using the commands:
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "OMST01" NORESETLOGS FORCE LOGGING NOARCHIVELOG
-- SET STANDBY TO MAXIMIZE PERFORMANCE
MAXLOGFILES 100
MAXLOGMEMBERS 2
MAXDATAFILES 1024
MAXINSTANCES 8
MAXLOGHISTORY 10210
LOGFILE
< your logfiles >
DATAFILE
< your datafiles >
CHARACTER SET <your character set>;So the steps are
Startup nomount with the pfile
Restore the datafiles using rman
Shutdown the database
Use above script to create the control files
It is possible you need to use the RESETLOGS option instead of the NORESETLOGS
