Question

亲爱的朋友们，我在我的测试m / c中安装了一个Oracle 11g实例。在我的开发m / c中安装了SQL开发人员。但是我无法连接到数据库，尽管两台机器都在局域网上，并且可以访问文件夹共享

我得到的错误信息是 “测试失败：IO错误：网络适配器无法建立连接”

虽然我可以在SQL开发人员在同一台机器上时连接到数据库。在此先感谢您的帮助。

# listener.ora Network Configuration File: C:\app\enduser\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

    

 SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\enduser\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\enduser\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = C:\app\enduser

And TNSName.ora is 

# tnsnames.ora Network Configuration File: C:\app\enduser\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL =

    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.18.2.127)
    )
  )

无法使用SQL Developer连接到Oracle Instance
