Our production control file is implemented as raw device.
If I backup controlfile using alter database backup controlfile to '/nfs/ctl_bkup' command and tries to restore on another machine (where same /nfs is mounted) by refering to the file as /nfs/ctl_bkp it mounts successfully. But if copy /nfs/ctl_bkp to a raw device on second machine (say /dev/rcontrol) using cp or dd if='..' of='..' command it gives error can not identifiy control file.(ora-205). What is wrong here. What is the method to convert a control file created from 'alter database backup controfile' to a raw device control file on another machine.

You need to edit the pfile and alter the location of control_files.

Yes I have edited teh parameter and pointed it to /dev/rcontrol but it shows ora 205. The problem seems to be related with the copying from file to raw device. Any Help????
