How to multiplex Control Files in Oracle

Control File is a physical component of every Oracle Database, it is a small binary file, which records database structure. Control File includes information like database name, name and location of data files and redo log files, database creation timestamp, current log sequence number, checkpoint information. Additionally if we use RMAN for backup and we do use RMAN catalog, information about RMAN backups is stored in control file. Oracle Database requires at least one Control File to operate. Control Files must be accessible all the time the database is open.
