RMAN Raise ORA-19913 ORA-28365 On Restore from Cloud Backup

First I think was some error with Database Backup To Cloud, when testing. Then I realized it was a simple mistake by myself.

Let me show you. First trying to restore datafile:

[oracle@mydbsrvr archivelogs]$ rman target /
RMAN> restore datafile 6;
Starting restore at 03-MAY-2016 20:00:30

ORA-19870: error while restoring backup piece 0sr4mdun_1_1
ORA-19913: unable to decrypt backup
ORA-28365: wallet is not open

Ok, it might happen because I forgot to set encryption password:

RMAN> SET ENCRYPTION ON IDENTIFIED BY "matheusdba" only;
executing command: SET encryption
RMAN> restore datafile 6;

It hapen again?
This point I suspect some kind of bug… But it was my mistake and is not related to Cloud, but to Encryption use. To undestand:
For Backup: Use ENCRYPTION
For Restore/Recover: Use DECRYPTION

Obviously, but take me a minute to realize…

Setting decryption, and problem solved:

RMAN> set DECRYPTION identified by "matheusdba";
executing command: SET decryption
RMAN> restore datafile 6;
Starting restore at 03-MAY-2016 20:00:58

See ya!
