Multiplex control file in 11gR2 RAC ASM using RMAN

After creating 11g R2 RAC database for the EBS R12, we wanted to enable multiplexing for the control files. Oracle recommends multiplexing the control files . We are using ASM for the storage of control files.

At the time of creating the database by dbca we can do multiplexing or we can also do later manually as described below.
Goal:- We have control file in the +DATA disk group and we want to also keep it in another disk group +OCR_VOTE for multiplexing.
