If they're just renaming the disks where the datafiles reside, then the
backup controlfile is the way to go.
However, if they're renaming the disk where the Oracle Home resides, then
you need to go edit the registry. Be sure and make a backup of the
registry before you start the edit.
Unasked, of course, is the question of why they would need to rename the
disks? Changing network drive numbers is reasonably common but since
Oracle8i on WinNT doesn't support network mounted drives this couldn't have
any impact on the database. Changing the internal drive letters either
involves spoofing the CMOS or the OS so that it thinks that drives are
mounted in a different order or actually changing the controller
connections. Maybe there's some reason to do this but I can't think of it.

Ron,
You're making this way too dificult.
To reorg the drive names on NT/2000:
1. Backup your database (just a good thing to do)
2. ALTER DATABASE BACKUP CONTROLFILE TO TRACE; - Generates a
script with all the datafiles listed in it.
3. Edit init<sid>.ora and any ifile linked configs that point to
drive paths. (Backup originals first).
4. Edit the controlfile script generated in #2 to show the new
paths.
5. Shutdown the database
6. Rename the devices at the NT/2000 level
7. in svrmgrl or sqlplus (8i or 9i) run the script from #4.
8. Recover database if necessary. May need to do a recover until
cancel and cancel it as soon as it asks for archived logs.
We recreate instances doing this all the time to create dev and test
systems. By recreating the controlfile you can rename all the dbfiles
at once. If you can't take the system off line, it will be very tedious
as Ron mentioned. Also if you want to change the location of SYSTEM
tablespace, you have to take the system off line.

Sonja,
It is a complicated process to rename disk drives in the Oracle
environment. Depending in the drives that Oracle uses and what are
changes(renamed) could really cause you frustration.
The initxxx.ora lists the current location of the controlfiles,
logfiles, dump dirs, trace dirs, etc.
You will have to startup the database (if it can find the controlfile)
and "alter database rename .. to .." for each of the effected datafiles. It
can be a long and detailed process. These are just a few thoughts off the
top of my head.
Make notes and document everything to CYA.
Good Luck

List hi!
Oracle 8.1.7 on WinNT.
Our Windows guys want to rename disc drives for some administration
reasons.
I'm really in UNIX so I'm wondering could you give me some advices on
this
matter.
As far as I know, I have to recreate control files, with new drives. Is
there anything else I should do? Some Windows stuff?
TIA,
Sonja
