無法連接到Oracle Express Edition

-1

我與Oracle Express Edition有問題。我可以通過使用sqlplus打開並運行數據庫中的命令，但後來我嘗試使用SQL開發人員連接到數據庫，但它不起作用。這很奇怪，因爲我有很多其他遠程Oracle數據庫，我可以通過使用sql developer或其他工具如IDEA連接到它們。聽衆可能有問題嗎？無法連接到Oracle Express Edition

當我嘗試連接時，我得到超時連接到端口1521。

Connection to @myhost.company.com failed.

您需要發佈錯誤。 – Ravi

連接到端口1521（這是偵聽器的標準端口）超時。 –

你能發佈錯誤的截圖嗎？ – Ravi

在此配置中，listener.ora和tnsnames.ora。只能在本地數據庫上建立連接，不能建立到數據庫的遠程連接，因爲偵聽器只偵聽IP本地主機。您必須將外部IP添加到偵聽器配置。的listener.ora

LISTENER = 
     (DESCRIPTION_LIST = 
     (DESCRIPTION = 
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) 
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)(IP=V4_ONLY)) 
      (ADDRESS = (PROTOCOL = TCP)(HOST = <IP DB server>)(PORT = 1521)(IP=V4_ONLY)) 

    ) 
)

添加端口1521和數據庫服務器上的防火牆端口範圍（32768-65536）一個異常，這是必要的SQL * NET協議。在客戶端機器上，您需要修復tnsnames.ora，需要將localhost替換爲數據庫服務器的IP地址。

XE = 
    (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = <IP DB server>)(PORT = 1521)) 
    (CONNECT_DATA = 
     (SERVER = DEDICATED) 
     (SERVICE_NAME = XE) 
    ) 
)

謝謝。但這不是問題。查看更新的文件。 –

診斷到數據庫的網絡連接。 1）'telnet myhost.company.com 1521' 2）'tnsping XE 10' 3）'sqlplus user/password @ XE' –

我沒有telnet。我已經運行了最後兩條命令並添加了結果。 –
