SQLDeloper IO 錯誤: The Network Adapter could not establish the connection
在Linux虛擬機器上安裝好oracle之後，在主機上安裝了SQLDeveloper，想用SQLDeveloper連線Linux虛擬機器上的oracle，做簡單的測試。結果輸入連線資訊，一測試就報：執行請求的操作時遇到錯誤:
IO 錯誤: The Network Adapter could not establish the connection 供應商程式碼 17002
上網查了一下，說是監聽裡host後邊為主機名，應該為IP地址。結果改為IP地址，結果還是報錯。後來說是防火牆的問題，結果改了把虛擬機器上的防火牆關了，重新連結，成功了！
看看網上的總結，mark一下：
1、監聽或者網路配置裡的IP地址錯誤；
2、防火牆遮蔽了監聽埠；
4、監聽沒有啟動。
