If I understand you correctly, you are trying to
clone a RAC datababase on ASM to a single instance database.
Right?
Use RMAN.

Edit the init.ora of auxillary and do appropriate changes.

RMAN> run{
2> allocate channel c1 type disk format '/oracle/backup/%U';
3> backup database;
4> backup archivelog all;
5> }
now i have copy all rman backup on development database.
startup the development database with rac database pfile with removeing some rac parameter.
now start rman at development database
rman target / nocatalog
estore controlfile from '/u01/oracle/oradata/c-610677177-20070212-00';
Finished restore.
RMAN> alter database mount;

Entry for undotbs is missing in your set newname.

Now it's successfully restored at my non ASM system.
During operation i found error "ORA-00600" when i restart databse in openreset log mode. basically there is a bug, which you have to patched and again restart the database in open resetlog mode. now logs file has been created and works fine.

Mash!
May you correct me if I am wrong?

If kumarrajnishgupta copy all of backup files (backupset) into the new_host, and he did not use catalog, in this case, he used control_file, then, he did not use command catalog in his rman's script. Why did he complete those task? I really do not understand.

Steps:
1. Use command "Backup full (or incremental level 0)" in target DB, including archive_logfile,control_file,spfile.
2. Use RMAN to complete these tasks in destination DB:
2.1: Restore controlfiles
2.2: NoMount DB
2.3: Restore spfile
2.4: Mount DB
2.5: Catalog backup files with new path in destination DB
2.6: Set newname for datafiles
2.7: Rename REDO log files
2.8: Restore Database
2.9: Switch all datafiles
2.10: Recover database
2.11: Open DB resetlogs.

Thank you!

Dear Tran
When you restore RAC Database controlfile at Development Database ( or clone Database ) like this
RMAN>restore controlfile from '/u01/oracle/oradata/c-610677177-20070212-00';
then it stores all info whatever in control file at RAC Database even RMAN backup Path.
and when you run "show all" at Development Database it shows like same as Rac Database "show all"
RMAN>show all
