When running the deinstallation tool, you can use a response file instead of responding to each prompt individually.
The deinstallation tool uses the information you provide, plus information gathered from the software home to create a response file. You can alternatively supply a response file generated previously by the deinstall.bat command using the –checkonly option and -o option. You can also edit a response file template located at Oracle_Home\deinstall\response\deinstall.rsp.tmpl to create a response file.
