 Hi

I have a simple question regarding multiplexing controlfile .

current controlfile locates in ASM .

I have no idea how to make another copy of it (so i can  use alter system set control_files command to set the second one as well. )

should i use dbms_file_transfer.copy_file?

also is there any simple way for recreating control file.(for example is it correct i issue

ALTER DATABASE BACKUP CONTROLFILE TO '+DATAGRP/CONTROLFILE/controlfile2.ctl';  do this task? then i set 

alter system set control_files='+DATAGRP/CONTROLFILE/controlfile1.ctl','+DATAGRP/CONTROLFILE/controlfile2.ctl' scope=spfile;)

Howdy, Stranger!
