Mike, I agree with what everyone else said. I wonder what this person was talking about? Maybe he meant while the database stayed up? Just remember that all the mount points need to named exactly the same on both machines. But this is obvious.

I know I have done this before, but I was just in a meeting where someone told me that you can't do this with Oracle, and that they tested it. This is with 9i by the way Thanks -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
