Were they possibly referring to things like missing registry entries or
incompatible (or missing) Oracle binaries, such as older versions and the
like?
Even on Unix you would need to make sure that the "oracle" user and "dba"
groups existed and that path setups were correct. It helps if the uids and
gids match so if your database files are on file systems you don't have to
chown them. Also likely some things not on the disk set for the database per
se like tnsnames.ora and listener.ora might need updates.
All that said, this is a pretty normal thing to do, and it is not rocket
science to prepare a server to accept a new database entirely contained on
freshly mounted disks. This has pretty much worked since at least Oracle V5.
If I recall correctly the host name was part of the password encryption
prior to V5 and that caused problems.

Subject: Disk failover
Hi All,
Can someone please confirm for me the ability to unmount a set of disks on
Server A, mount those same disks onto Server B (Same O/S, unique named
disks), and bring up the database on server B. 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
