Trying to uninstall a Oracle 11g RAC from a Windows Server 2008. Following instructions on: http://docs.oracle.com/cd/E11882_01/install.112/e25666/rem_orcl.htm
I was able to run batch: C:\app\oracle\product> 11.2.0\dbhome_1\deinstall\deinstall.bat
Final messages was about succesfully uninstallation.
However, I had problems trying to delete folder c:\app. According to Oracle forums, on Windows there are known problems that generic process 'svchost.exe' locks some Oracle DLLs at boot time. To solve the issue I followed instructions:
1) rename %ORACLE_HOME%\bin to something else 2) reboot the machine 3) now delete the complete folder
Then I went to Registry and deleted key: HKEY_LOCAL_MACHINE\SOFTWARE\Oracle
Then reboot machine.
Problem is that Oracle Services still exists:
Those services point to erased executables like:
because C:\app folder was deleted.
What should I do to remove those services from Windows?
