來自 Oracle 11g 的遠端連接錯誤

我正在嘗試從連接在同一網路中的另一台電腦連接到我的 Oracle 數據庫 11g。

在連接數據中，我輸入了伺服器機器的地址，但它不允許我連接。如果它允許我連接，則從伺服器電腦，但不能從另一台電腦：

Error de E/S. The network adapter could not establish the connection

機器 1 - Oracle 伺服器：本地訪問連接：是

機器 2 - 客戶端遠端連接：失敗

兩台機器在同一個網段：192.168.x.machine1 192.168.x.machine2

您好問題的解決方法：

將 Windows 防火牆例外添加到：

Oracle_home\bin\oracle.exe - Oracle 數據庫執行檔

Oracle_home\bin\tnslsnr.exe - Oracle 偵聽器
