Oracle  11g 安裝完成後，只能在本機訪問，希望其遠端計算機也能訪問，剛開始直接修改listener.ora檔案

    # listener.ora Network Configuration File: C:\app\Administrator\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\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )


   LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost

  將localhost直接改為本機Ip地址，重啟監聽服務

    停止監聽：lsnrctl stop 

    啟動監聽：lsnrctl start 

    檢視監聽：lsnrctl status 

結果失敗。

正確的方式，執行Net Configuration Assistant，修改監聽配置，一步一步即可，無需修改任何資料

結果listener.ora檔案變為：

# listener.ora Network Configuration File: C:\app\Administrator\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\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )


LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-VI5UF46V3UG

Host處變為主機名，這樣遠端計算機就可以訪問伺服器了。

無需修改服務方式為共享還是專用，無需修改IP地址，可能該向導在後面自動做了很多工作
