Hi,

I did database restoration on a new host successfully by taking the following steps:

1-set oracle_sid=orcl
2-RMAN> CONNECT TARGET /
3-shutdown immediate;
  SET DBID 1354693553
4- STARTUP NOMOUNT
5-RUN{
  RESTORE SPFILE
  TO PFILE 'C:\Users\Administrator\Desktop\NewPfile\initorcl.ora'
  FROM 'C:\Users\Administrator\Desktop\53 Files\LstBack\FULL-16-1-1393-8-54-10-0-  ORCL-0NP4V2MR-23-1.BAK';
  SHUTDOWN ABORT;
}
5--STARTUP FORCE NOMOUNT PFILE='C:\Users\Administrator\Desktop\NewPfile\initorcl.ora'
6-RUN{
  RESTORE CONTROLFILE FROM 'C:\Users\Administrator\Desktop\53 Files\LstBack\FULL-   16-1-1393-8-54-10-0-ORCL-0NP4V2MR-23-1.BAK';
  ALTER DATABASE MOUNT;
}
7-
RUN{
RESTORE DATABASE ;
RECOVER DATABASE;
}
8-restore spfile from  'C:\Users\Administrator\Desktop\53 Files\LstBack\FULL 16-1-1393-8-54-10-0-ORCL-0NP4V2MR-23-1.BAK';

But after shutting down the database and start up it,the following error occurred:

SQL> startup
ORACLE instance started.

Total System Global Area 8384552960 bytes
Fixed Size                  2192456 bytes

ORA-00205: error in identifying control file, check alert log for more info

why? While I've already restoring controlfile and spfile.

When you restore a file to an ASM diskgroup, it will be created with a new incarnation number. Therefore, the name in your parameter file will no longer be correct. You need to compare the name it is looking for (as shown in your error message) with the name of the file that was restored to confirm this.
The solution is to create an alias for the file: an alias is a stable filename that ASM will map to whatever the actual filename happens to be (including the incarnation number). You can do this explictly (look up ALTER DISKGROUP...ADD ALIAS...) or implicitly in your RESTORE CONTROLFILE command.

Thank you John Watson, you said right.
I found the correct name of the controlfile using ASMCMD>+Data/orcl/controlfile ls command, then I modified spfile and database start up correctly.
