經過查詢發現需要配置監聽檔案：

D:\ITSoft\oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora

原先檔案:

# listener.ora Network Configuration File: D:\ITSoft\oracle\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 = D:\ITSoft\oracle\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\ITSoft\oracle\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 = D:\ITSoft\oracle

 

後來更改為（更改後需要重啟oracle監聽服務）：

# listener.ora Network Configuration File: D:\ITSoft\oracle\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 = D:\ITSoft\oracle\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\ITSoft\oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
	#增加內容
	(SID_DESC = 
      (GLOBAL_DBNAME = orcl) 
      (ORACLE_HOME = D:\ITSoft\oracle\product\11.2.0\dbhome_1) 
      (SID_NAME = orcl) 
    ) 
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\ITSoft\oracle
