    How to uninstall 11gR2?

    846231
      Hi All,

      I want to un-install my 11gR2 on Windows 2003 Server.
      I want the universal installer to remove the OracleHome (registry) and the physical home > C:\oracle\product\11.2.0.1\db_1
      But when I try to run deinstall.bat it will just hang.

      Any idea how to cleanly uninstall it? Without deleting it by force.



      Thanks a lot,

            11.2 onwards , there is an official deinstall utility available. If I am correct , OUI doesn't do the install anyways from 11.2 . Download the utility from OTN and use it to do the deinstallation.

            HTH

              Remember, manually editing your registry can be very destructive and force an OS reinstall so only do it as a last resort.
              Yikes....Im afraid I will mess-up the prod server :( ....its okay if I will just be terminated so I can rest from stress :) but what if I will be jailed because of the precious data loss :(. Is it possible that a person can be jailed because
              of millions worth of data loss?

                  Hi Aman,
                  Download the utility from OTN and use it to do the deinstallation.
                  Can you help me about the link please. I tried searching the deinstallation software but it pointed me to the installer instead.


                  Thanks,

                    Don't believe that it going to be a disaster 100% of times, just could it be and it'a an advice.

                    Anyway you can do it with a safe method:

                        Knowing myself, I am very prone to disaster :D

                          Hi Aman,

                          I downloaded it but I can not see the instruction to deinstall :( inside the folder. only the deinstall.bat which is the same to the one we have in the OracleHome that hangs?

                          I am just confused. Are these files:

                          For 32 bit Windows,
                          http://download.oracle.com/otn/nt/oracle11g/112010/win32_11gR2_deinstall.zip
                          For 64 bit Windows,
                          http://download.oracle.com/otn/nt/oracle11g/112010/win64_11gR2_deinstall.zip

                          More updated than the one inside the OracleHome installer?


                          Thanks agian,
