Question

我遇到此错误TNS：尝试从Linux远程计算机连接到Oracle DB时，错误地指定了网络服务名称。

我看到很多相同的帖子，但没有帮助，所以开始新的帖子。

详情

我在VMWare Fusion上有一个关于VirtualBox和Oracle DB的linux。两者都安装在Mac El-capitan上。

我可以使用sqlplus命令与oracle客户端12.1.0.2连接到Oracle DB。但不是来自Linux。

已配置设置

根据所有其他帖子的建议，我已涵盖所有设置：

Linux VM上的oracle DB的主机名。
将ORACLE_HOME，ORACLE_SID设置为DB名称。
检查侦听器配置。
连接（ping / telnet）到Oracle DB。
使用Linux VM中的sqlplus命令测试连接。

我的tnsnames.ora：

# tnsnames.ora Network Configuration File:

XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = XXX.YYY.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

AAA =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = XXX.YYY.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

sqlplus连接 - 成功尝试

来自linux的1521端口的Telnet连接

有人能说清楚为什么会这样吗？
