Oracle11 Full Unload method

(previously because I did not know the computer is because of the installation of Oracle, the result of up to two weeks of boot speed of 10 minutes, before only a minute!) You can imagine Oracle's service startup powerful, knowing that I immediately uninstall it off! ）

First, uninstall Oracle before oracle11g there is a situation where uninstalling is not clean, causing the installation to fail again, running services.msc to open the service, stop all services of Oracle.

Second, oracle11g with a uninstall batch processing \app\administrator\product\11.2.0\dbhome_1\deinstall\ Deinstall.bat Run the batch program will automatically complete the Oracle uninstall work, and finally manually delete the \app folder (may need to restart to delete)
