Database Software

When I run the dublicate target for standby dorecover command, I took a error which is ORA-01102: cannot mount database in EXCLUSIVE mode. Product system is Oracle 11g RAC and Standby database is 11g single instance. I edited pfile for stanby according to documents. But I did not pass this part.

RMAN> duplicate target database for standby dorecover;
