Paul,

My guess is that the 3rd party software is looking for the default = oracle home, which is probably set to the first Oracle install in this = case would be the 9.2 install. First thing I would do is change the = default home to the 8.06 home and see what happens. Messing with the = registry entries can be messy.

Subject: Registry remnants after uninstalling 9.2 on W2K server

OK, there's no excuse for such carelessness: The development team wanted = to revert a W2K server, which had Oracle 9.2 installed (but no databases = yet) to Oracle 8.0.6, in order to test a migration path. So I stopped = the Oracle services, ran the Oracle Installer and uninstalled 9.2, = removed the remnant directories, then rebooted the server. I then got = the install CD for Oracle 8.0.6 and installed it into its own Oracle = Home.

Fine - no problems.

Except that when the developers went to install their 3rd-party = application package, it threw up error messages which clearly showed it = was looking for files in the old Oracle 9.2 Home directories - which of = course no longer existed.
=20

Clearly I screwed up by not realising (I realise now!) that there must = have been lingering Registry entries relating to Oracle 9.2, which I = should have identified and deleted before proceeding with my = installation of Oracle 8.0.6.
=20

So my question is: is it a "safe" course of action to simply remove = those lingering 9.2 registry entries? If so, which entries should I = remove in order for the server to only regard itself as possessing a = single, 8.0.6, Oracle Home? (I've not been through this particular = process before, though I'm OK with making Registry edits in general). Or = is this too risky a procedure, and would I be better off uninstalling = 8.0.6, removing ALL Oracle registry entries (in which case, could = someone please give me a checklist of relevant entries?), and then = re-installing 8.0.6. As I mentioned, no database has been created yet, = simply Oracle software installed.
=20

Definitely one of THOSE days...
