出現(xiàn)該問題一般有兩種情況。

第一種是在你安裝完之后未配置監(jiān)聽（在此我暫時忘記安裝完之后有沒有配置監(jiān)聽）；
第二種是之前配置了監(jiān)聽但是系統(tǒng)未寫入到listener.ora文件中(在此我暫未搞明白什么時候?qū)懭耄⑶矣行┪磳懭胍部梢杂玫俏遗渲猛赀@些后的確可以用了，不理解但祝福)，所以只需要在該文件中寫入配置參數(shù)就可以了。

修改listener.ora

原listener.ora文件

# listener.ora Network Configuration File: C:\software\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 = C:\software\Oracle\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\software\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))
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.131.128)(PORT = 1521))
    )
  )
ADR_BASE_LISTENER = C:\software\Oracle

從上圖中我們可以看出我已經(jīng)配置過監(jiān)聽了，但是報錯是由于Oracle的地址沒有寫到SID_DESC中，在此我們將此寫入就可以了。

添加 記錄

	(SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = C:\software\Oracle\product\11.2.0\dbhome_1)
      (SID_NAME = orcl)
     )

修改后listener.ora文件

# listener.ora Network Configuration File: C:\software\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 = C:\software\Oracle\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\software\Oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
	(SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = C:\software\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))
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.131.128)(PORT = 1521))
    )
  )
ADR_BASE_LISTENER = C:\software\Oracle

tnsnames.ora

原tnsnames.ora文件

# tnsnames.ora Network Configuration File: C:\software\Oracle\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 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.131.128)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

修改tnsnames.ora數(shù)據(jù)

已標(biāo)黃，就修改了地址。

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost )(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)

修改后tnsnames.ora文件

# tnsnames.ora Network Configuration File: C:\software\Oracle\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.


LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))



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

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost )(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
