grid infrastructure 提示“[INS-40404] The installer has detected a configured instance of oracle grid infrastructure software on the server!

今天是2013-12-03，描述一下出現這個錯誤的過程，我沒按照正常的方式刪掉 grid infrastructure，而是直接刪掉了安裝目錄，但是并不知道在安裝grid infrastructure的時候會做什么隱含的操作，因此在我重新安裝的時候就出現了如下所示的錯誤。

這個時候，我嘗試了多種辦法，結果還是不行(其中包括再次按照正常卸載步驟去操作)。事情往往是這樣的，我們換一個思維角度往往就會有一個新的解決辦法。既然在重新安裝的時候出現這個問題，那么肯定可以從安裝腳本內容去分析是到了那一步才會提示這個錯誤：

上邊為安裝腳本，可以看到正是出現了上邊標紅部分才驗證不過去。

至此可以繼續進行安裝。
