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.
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.
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.
Definitely one of THOSE days...
