I am experimenting with the installation and deinstallation of Oracle 12.1.0 on Windows 7 x64 Ultimate Edition, and have come across some issues that I have been unable to resolve.
1) I am able to deinstall Oracle via the setup.exe installation file method, but not via the deinstall.bat method. When I attempt to run deinstall.bat on the command line, I receive the error message, "Unable to find auto generated response file. So, cannot proceed with deinstall clean action." However, according to the documentation, including a response file should be optional. Why do I receive this error? Also, when attempting to run deinstall.bat from Windows Explorer, the console window closes abruptly after running. Is this normal?
2) When attempting to run setup.exe for a silent install (single computer), using the command "setup.exe -silent -responseFile C:/app/db.rsp" I receive the error message, "[FATAL] [INS-32025] The chosen installation conflicts with software already installed in the given Oracle home. ACTION: Install into a different Oracle home." However, the silent install did not require me to specify an Oracle home name, and neither did the interactive install which the response file was generated from. I noticed a place in the response file where the Oracle home is specified. Is the user required to edit the response file manually to rename the next Oracle home, each time the response file is used for an install?
3) Is there a way to generate a deinstallation response file automatically, as one can do for the installation response file? On a likely related note, does the OUI include a GUI for deinstallation? I seem to remember finding one, but cannot locate it now.
