Home -> Community -> Mailing Lists -> Oracle-L -> RE: Registry remnants after uninstalling 9.2 on W2K server
I would uninstall again and this time go into the registry and under
local machine \ software delete the oracle key.

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.
=20
Fine - no problems.
=20
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...
