Removing Oracle especially Listener

[Flook M]

I am a tester and have to regularly uninstall software and reinstall it. unfortunately Oracle does not seem to be designed to do this. I have used the uninstall facility but this does not put the computer back to how it was before I installed it. I deleted the left over files in Program files and the Oracle folder that holds the ora92 files. I also deleted mention of Oracle path under Local_machine/Software in the Registry. I tried reinstalling but the Net configuration assistant would not reinstall the missing Listener files because it says the Listener is already installed. The software I am trying to use Oracle with cant find the listener because some files it needs are missing. I deleted all Oracle services and tried reconfiguring and renaming the listener to get it to reinstall but no luck. The PC is in a mess. What are the files/settings I need to delete to allow a full reinstall including for listener please?

Hi,

In order to completely uninstall Oracle from a windows system, make sure you do the following:
- delete the software files from the home directory (c:\oracle\ora92 etc).
- delete all the services that start with ORCL. ±8 services exist.
- Clean the oracle folders from the registry. under HKEY LOCAL MACHINE. You can run find orcl / oracle to find all the different folders.
- I would do a system restart at the end, to clear everything up.

This should do the work for you.
