Steps to uninstall Oracle11g from windows 7

Recently I got the strange work of deleting Oracle 11g from a windows 7 box. [Yeah, I know its a bad job :-)]
I used the OUI program to remove Oracle. However it gives a bad command line option to run the deinstall.bat file. I ran the bat file and I got some strange exception stack trace.

So its at this point that I decided to go the ‘hard way’ [manual un-installation]

Phase 1
Stop all Oracle services first.

1) START -> RUN -> Services.msc
2) Locate all Ora* services & click on STOP

Phase 2
1) Start -> RUN -> Regedit
2) Locate HKEY_LOCAL_MACHINE folder in the registry
3) Open Software folder
4) Delete the Oracle folder under Software
5) Open System folder in HKEY_LOCAL_MACHINE
6) Open CurrentControlSet folder within the System folder
7) Open Services
8 ) Delete all keys related to Oracle. Every key starts with “ORA..”
9) Close the regedit
10) Delete ORACLE_HOME folder
11) Delete the Oracle folder in Program Files
12) Reboot

At this point your machine should be free from Oracle.

I wish if Oracle could streamline this process …


Whitepaper – InstallShield

Dear Readers,
Recently, I completed my maiden assignment on InstallShield. I was asked to use complicated stuff like Database Interaction, setup within a setup & file I/O in InstallShield. I had some painful days learning InstallShield and then implementing these requests. The worst part of all this was that there aren’t much resources available over the internet. Nor I knew of anyone who could lend an expert advice.

So just to save someone from undergoing the same/similar experience again, I have come up with a short white paper on the database interaction part using InstallShield 2010. Hope you appreciate this noble work.
