RMAN: Recovery of missing datafile that is never backed up

Environment:
Oracle Database 11gR2 on Windows 7
DB in archivelog mode

Example:
Assuming that already a tablespace "TS1" is existing with one datafile, if not you can use the statements below.
 create tablespace ts1 datafile 'C:\app\Inam\oradata\orcl\ts01.dbf' size 10m reuse;



1-   Add the new datafile in the tablespace
SQL> alter tablespace ts1 add datafile 'C:\app\Inam\oradata\orcl\tsnew.dbf' size 10m;

Tablespace altered.

Do some activity
SQL> create table ali.newtable as select * from dba_objects;

Table created.

2- Now shutdown instance and then delete the datafile "tsnew.dbf" for which we don't have any backup. After this mount the database.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

SQL> startup mount
ORACLE instance started.

3- The missing datafile is the only datafile that needs recovery. In this case you do not have to restore anything. Archivelogs are restored automatically by RMAN as they are needed for the recover command.
