bring the DB to nomount mode
then do the below steps
rman target /
RMAN>restore controlfile from '/opt/oracle/backup/std_0vo6morv_1_1';
RMAN>alter database mount;
RMAN>restore daatbase from '/opt/oracle/backup/std_0uo6morg_1_1';
RMAN>alter database open resetlogs;
You need to set the correct DBID before you RESTORE CONTROLFILE.
After the RESTORE CONTROLFILE, you need to RESTORE DATABASE (and, after that, RECOVER DATABASE). If you are doing a Point In Time Recovery or an Incomplete Recovery, you need to SET UNTIL before the RECOVER DATABASE.
