Re: Strange problem with controlfile

Hi Sreejith,
I have seen this before. It has to do with the way OMF is handled on ASM.
The best way to do this is use RMAN to restore the controlfile to another
location.  See this note for details: *How to duplicate a controlfile when
ASM is involved [ID 345180.1]*
I have found ways to get ASM to recognize files with non omf names, but the
above is the cleanest supported way.
