How can I uninstall Oracle 11g from my laptop? The uninstall program that comes with the software doesn't completely uninstall all the components. I tried it with Oracle12c and it left a lot of programs. I tried to delete the files manually but some dll files in the BIN directory were are not accessible. I want to do the right thing with 11g. Any suggestions?
Thank you very much in advance.
There are some problems when I uninstall Oracle 11g (on Window 10) from my installed path "D:\app\" .This is my solution to remove oracle manually:
Delete D:\app{user}\product\11.2.0\dbhome_1
and all Oracle's files from D:\app\
If you can not delete these files, need to change the owner or add permissions
Properties>Security> Advanced> Change Owner> Advanced>Find now> Choose Users
Sometime you need to add permissions to Users: Properties>Security>Edit> Add Users> Allow ...
Delete C:\Program Files (x86)\Oracle, C:\Oracle
Delete C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Oracle -
OraDb11g_home1
Run regedit.exe>
delete HKEY_LOCAL_MACHINE/SOFTWARE/Oracle
delete HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ORACLE
Delete HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ora*
Start Run>Computer Management> System Tools>Local Users and Groups> Delete
all Oracle's users and groups
Restart windows.
Hope helpful for you!
First of all you should use the deinstall tool as recommended by Oracle.
Then if this fails have a look at this document: Manually Removing the Remaining Oracle Database Client Components (11.1), it provides detailed instruction how to remove everthing.
This documentation is for Oracle Client 11.1, however the principle should be the same for 12c. Actually the documentation for 10.2 is even more complete: Manually Removing the Remaining Oracle Database Client Components (10.2)
Perhaps some files are locked and you can not delete them by default, for example file oci.dll. Solution is to rename the file, e.g. oci.dll_x and then reboot your PC. After reboot you can delete the file.
Note, in case you installed 32-bit Oracle the Registry key is HKLM\SOFTWARE\Wow6432Node\ORACLE\... instead of HKLM\SOFTWARE\ORACLE\...
Before deinstalling oracle software, make sure you have deleted the oracle databases (and other services) running from the ORACLE_HOME
I have written about the different methods in which you can remove Oracle software from Linux server:
Using deinstallation tool with runInstaller
Using deinstallation tool under ORACLE_HOME
Manual Oracle uninstall

In 2022, the question asked in how-to-prevent-oracle-sql-developer-from-writing-to-appdata-roaming is still a bit of a problem. While the -Dide.user.dir option does allow you to move the SQL Developer directory from %APPDATA%, the application still creates a sqldeveloper directory in %APPDATA% that contains a <version>/product.conf file.
What option needs to be added to move this directory as well? I am using version 21.4.3 of SQL Developer. Thanks in advance for any help you all can offer.
You need to convince SQL Developer that it's not actually running on Windows, but is instead on Linux or a Mac.
Otherwise, SQL Developer is designed to do EXACTLY as you describe/observe.
The -Dide.user.dir doesn't let you move those files per se, it more accurately allows you to mirror them somewhere else.
I can't install Oracle Database, because I have error
[INS-20802] Oracle Database Configuration Assistant failed
My PC: Windows 10 Pro;
Intel core I3; 100+ gb free space
My logs: https://1drv.ms/f/s!AsSF97QkK8MmjyxT7WBwRcyscMtE
I already tried:
disable UAC
Disable antivirus
Install Microsft vc 2010 x32
editing localhsot
root for perl.exe
Appreciate if someone can help me!
Look into your %Program Files%\Oracle\Inventory\logs where you will find the reason for error.
I also encountered similar problem where I installed Oracle 18c XE,
Oracle Database 18c we are introduced to a new concept: Image Based Installation.
In Image Based Installation the Oracle Universal Installer of 18c takes the location of our setup.exe file and assigns it as its db_home location. That’s why before we start extracting the content of this file, we first need to decide where we want to create our db_home directory.
Mistake I made was I had the setup.exe in D://drive and for others location left as default(which is C:/ drive)
Solution:
Copy and extract the entire folder which contain setup.exe in C://
Drive.
Manually remove all the files in in C:/Program Files/Oracle
(including Oracle folder)
Run the setup.exe as Administrator
Leave the other configuration paths as default
(Additional : Satisfy following condition when configuring the password
Oracle recommends the following guidelines when prompted for a password.
Contains at least one lowercase letter.
Contains at least one uppercase letter.
Contains at least one digit.
Is at least 8 characters in length.
Uses the database character set, which can include the underscore (_), dollar ($), and pound sign (#) characters.
Should not be an actual word.

You can find in your logs:
SEVERE: [Jan 18, 2019 4:32:04 PM] [FATAL] [INS-35955] The Database software home
(C:\ORACLESOURCE) is already registered in the central inventory. This tool can only be
used in a non-registered Database home.
ACTION: Choose a different location as Oracle home.
Try install Oracle in another directory.
I don't know what I did. I accidentally installed multiple Oracle on my machine. It could have been that I did not realize I installed successfully. I end have 5 Oracle home folders
anyway, I kept having problem connecting to Oracle. SQL developer works, but sql/plus and C# have not been working.
There is a chance multiple Oracle Home cause the problems. I don't know. I decide to uninstall and reinstall again and see what happen
I run deinstaller. It removes successfully on dbhome_5 folder. The files in dbhome_5 folder still exist, I cannot uninstall Oracle in other 4 folders
dbhome_1
dbhome_2
dbhome_3
dbhome_4
Deinstaller could not detect anything. Therefore, I cannot uninstall
Those 5 instances still exist.
I can install against. That mean dbhome_6. I don't know it will create confusion again.
How to uninstall / completely remove Oracle 11g (client)?
This page tell us how to clean remove. I don't to do uninstall because I cannot. Do I have to manually remove all the files?
I just want the machines to have clean environment before the next installation
I have the feeling that was what happened before. I fail to configure. I uninstall. Then I have 5 folder
I am using Oracle 11 universal installer version 11.2.1.0
Thanks
Having done this before myself, I know how confusing it can get.. worse even, that the configuration for different oracle data access clients about which home to use can be in different places, so your sql plus can end up using one install whereas your c# is using another
I'd recommend to follow the manual removal instructions you found on the linked page; do it for every oracle home you can find (search your entire drive for e.g. tnsnames.ora)
Remove everything (maybe preserve any tnsnames you find as it will make configuring the reinstall a bit easier) and then reinstall it, just once this time:)
unexpected Crash of windows took place. I dont have a metadata backup. After reinstalling windows i have taken the old database folder back up which has all
system01.dbf
sysaux01.dbf
undotbs01.dbf
Temp01.dbf
users01.dbf
redo01.log
redo02.log
redo03.log
Please share your recommendations to go forward.
Easiest option is to install Oracle with the same version as the old one, create a database with the exact same name as the old one and at the exact same location as the old one.
Once you have that working, shut down the database. Then copy your backup files over the new files. Start the database.
As we tried to deploy a new project that connects to an Oracle database, we encountered some problems..
On my development workstation, I have my Oracle dll's installed in c:\app\oracle\product\11.2.0\client_1\BIN but on the development web server, it's in stalled in c:\oracle\product\11.2.0\client_1\BIN (noticed NOT in the app folder).
When an application is deployed, those dll's that are referenced need to be in the same location on both machines. So needless to say, we get an error from the development server.
In order to fix this, we tried a few things -
Move the Oracle install to c:\app... on my machine and rebuild from my development machine. This didn't work because there are relative dll's that rely on that path.
Because 1 didn't work, we tried to reset the environment path variables to c:\oracle on my machine. That didn't work.
tried to copy the needed dll's into my bin directory because my understanding is Visual Studio will build from the GAC, then from the bin directory. That didn't work.
Knowing that re-installing Oracle on the development server to c:\app\Oracle isn't an option, has anyone else come across this problem?
You need to make sure that your Oracle install is setup correctly. I have a few utilities that can assist with this.
Step 1 -
The utilities below will confirm first that .net works with Oracle on your server
http://tsells.wordpress.com/2010/02/18/oracle-connection-tester-for-net-applications/
Step 2 -
If the utility above worked - then go to step 3. Otherwise - .net can't see oracle on this machine. Check your path statement first - make sure the oracle bin directory is pointing to is the correct one. If not - change it and try again.
If this doesn't work - I recommend uninstalling oracle completely and reinstalling. Use the following steps.
Stop any services (start - run - services.msc) below that are running
oracle mts recovery
Distributed Transaction Coordinator
Delete all oracle directories from the file system (C:\app, C:\Program Files | C:\Program Files (x86(
Remove Oracle entries from the system path
Remove any Oracle entries from the environment variables (if they exist) such as ORACLE_HOME
Open the registry editor (start -- run -- regedit) and remove any oracle entries from the following key
HKLM\Software\
HKLM\Software\Wow6432Node (64 bit machines only)
Empty Recycle bin (makes me feel better) :)
Reboot the machine
Download one of the two items
Oracle Client Installation (full)
ODAC (Oracle Data Providers)
Install them (make sure if you choose the client version - you use a minimum of the runtime install) - do NOT use the instant client - it never seems to work properly.
Copy the TNSNames.ora file over
Test with the utility again. It should be successful.
Step 3 -
If the utility above worked - then you need to make sure the bit level of your application matches the bit level of the Oracle client installation. For the app - this will be the bit level of the application pool.
Notes - the oracle.dataaccess.dll file in the bin folder is used to help create the images (ngen, aspnet compilation). Once you attempt to call the oracle data provider for .net - it is routed to your client installation to perform the actually data access.
