本人的問(wèn)題已解決，先在安裝oracle的服務(wù)器上黑窗口輸入tnsping，提示說(shuō)no listener，這是監(jiān)聽(tīng)服務(wù)沒(méi)有打開(kāi)。 打開(kāi)服務(wù)后還是不行，最后原因是服務(wù)器的網(wǎng)絡(luò)有防火墻的問(wèn)題，關(guān)掉防火墻連接成功

第一反應(yīng)是監(jiān)聽(tīng)沒(méi)開(kāi)：

測(cè)試了一下， 連接超時(shí)沒(méi)用ping 通

我登陸到遠(yuǎn)程服務(wù)器上，查看了一下監(jiān)聽(tīng)的狀態(tài)

看到監(jiān)聽(tīng)也正常，本地連接進(jìn)去也很正常。

我想了一下本地能訪問(wèn)遠(yuǎn)程連接不上是不是防火墻問(wèn)題，于是我關(guān)閉了windows防火墻，果然在遠(yuǎn)程tnsping 能ping通了；

結(jié)果：應(yīng)該是防火墻有改動(dòng)了，最后把 服務(wù)器防火墻的 ip和端口添加為例外，應(yīng)用恢復(fù)正常了。

總結(jié)： 一般遇到tns 的問(wèn)題通常都是監(jiān)聽(tīng)或者是網(wǎng)絡(luò)問(wèn)題 ? ? ? ? ? 1. 查看監(jiān)聽(tīng)是否正常 ? ? ? ? ? 2. 查看 ip 或端口有沒(méi)有改動(dòng) ? ? ? ? ? 3. 查看防火墻

總結(jié)
