Ron,
You're making this way too dificult.
To reorg the drive names on NT/2000:

Backup your database (just a good thing to do)
ALTER DATABASE BACKUP CONTROLFILE TO TRACE; - Generates a script with all the datafiles listed in it.
Edit init<sid>.ora and any ifile linked configs that point to drive paths. (Backup originals first).
Edit the controlfile script generated in #2 to show the new paths.
Shutdown the database
Rename the devices at the NT/2000 level
in svrmgrl or sqlplus (8i or 9i) run the script from #4.
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
