Can I retrieve my db (if I don't activate controlfile autobackup ONE)?

Hi all;

Unfortunately, I deleted all the CRD of local database files.  I have backup rman.

But I did NOT control file autobackup.

$ rm *.

$ ls-> NO HRMS CRD of for DATABASE FILES

SYS > close the demolition;

ORACLE instance stops.

SYS > startup nomount;

ORACLE instance started.

Can I recover my database?

File "o1_mf_ncsnf_TAG20141110T012555_b5zkrhqp_.bkp" is probably a backup controlfile.

Use RESTORE CONTROLFILE FROM "path_to_file".

(Note: you must SET DBID before RESTORE you CONTROLFILE because Oracle uses the DBID to test if the controlfile is the same database.)  You can obtain the DBID of newspapers of the previous series of rman or your documentation)
