我在服务器上安装了 oracle 11.2.0。一切都很好，直到星期一。现在我无法通过客户端连接到数据库，SQL 开发人员，SQL Plus。

所有服务都已启动。我不知道这有什么问题。

Answer 1

请做：

Check hostname status from OS.

Check your firewall and windows 64 is not forbidding port access.

Answer 2

此设置有很多问题 - 例如，listener.ora 中 test3 的侦听器 SID/SERVICE_NAME 定义在哪里？无论如何，您可以在 windows.

下没有特定的侦听器定义而逃脱

不过我觉得你的问题很容易解决，线索在这里：

Service "test3" has 1 instance(s).
Instance "test3", status READY, has 1 handler(s) for this service...

您的 tnsnames.ora 正在寻找服务名称 TEST3

TEST3 =
 (DESCRIPTION =
  (ADDRESS_LIST =
   (ADDRESS = (PROTOCOL = TCP)(HOST = SERVERNAME.DOMAIN)(PORT = 1521))
  )
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = TEST3)
)
)

替换

(SERVICE_NAME = TEST3)

和

(SID = test3)
