Oracle Backup and Recovery - How to restore tablespace in case of NO backup?



I take full  backup with RMAN, after backup I will create tablespace and a user with default tablespace new tablespace and a table on this user schema. After those I loss new tablespace's datafile. RMAN restore datafile  without backup of this datafile.

I think, this video will be  intersting for Oracle DBA's. You can watch  How to restore tablespace in case of NO backup? on youtube.
