    Uninstalling Oracle 11g RAC from a Windows Server 2008

    user521219
      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 on Windows Services(services.msc). So I still see:

      - Oracle Object Service
      - OracleASMService+ASM1
      - OracleJobSchedulerINTER1
      - OracleOHService
      - OracleOraCrs11g_home1TNSListener
      - OracleOraCrs11g_home1TNSListenerLISTENER_SCAN1
      - OracleServiceINTER1
      Those services point to erased executables like:

      C:\app\11.2.0\grid\BIN\TNSLSNR

      because C:\app folder was deleted.

      What should I do to remove those services from Windows?
