oracle deinstall doesnt work. I guess you have to reinstall windows?
558970Mar 26 2012 — edited May 20 2012we could not get 11g R2 to work on a new Windows 2008 server.
So now we need to remove it.
According to this document: http://docs.oracle.com/cd/B28359_01/install.111/b32007/deinstall.htm#CIHJCJHC
The correct way to uninstall is to:
1) Start Oracle Universal Installer.
2) Click the Deinstall Products button
3) Select the Oracle home you wish to remove.
4) Check the boxes of components to remove (tediously you have to check every box)
5) Click remove.
But when you do this, a dialogue pops up and says:
"please run the command c:\app\oracle\product\11.2.0\dbhome_1\deinstall\deinstall to deinstall Orcacle".
WTH?
Why is the documentation wrong, and why do they tell you to use the installer to deinstall, if its just going to tell you to run a command line?
When you run this, it says:
Specify all Single Instance listeners that are to be de-configured [LISTENER]:
WTH? How does one specify all single instance listeners?
There are litterally hundreds of pages of documentation on how to uninstall oracle - something which should be a trival task. But I cant find any mention of how to find out how to specify all single instance listeners.
In desperation, I tried hitting enter, at least takes you to the next gotcha:
The details of database(s) ORCL have been discovered automatically. Do you still want to modify the details of ORCL data
base(s)? [n]:
WTH? Why would I want to modify the details of a database? I want to delete oracle and everything it has installed, not modfy details. Should I say yest or no? I have NO idea. Give me more options, or dont ask at all!
If I say y, it says:
Specify the type of this database (1.Single Instance Database|2.Oracle Restart Enabled Database) [1]:
What? I have NO idea what the difference between these two options are. This was never mentioned in the installation process, so way ask now? Why doesnt it just delete the DB as I requested?
At this point I gave up.
Oracle is the worst SW on windows I have seen. Its impossible for a unix and windows sys admin with 20 years experience to even install or remove.
