解決 ORA-12514: TNS: 監聽程序當前沒法識別鏈接描述符中請求的服務(轉)

數據庫忽然鏈接不上了，報出問題是ORA-12514：監聽程序當前沒法識別鏈接描述服務中請求的服務，因而請教老師，老師在網路上找到這篇帖子解決了個人問題。

 

 

系統環境：Oracle 11.2.0.1.0 R2

下面操做默認在安裝Oralce數據庫的服務器上運行。

1）確保Oracle 基本服務都已啓動

    OracleDBConsoleorcl

    OracleOraDb11g_home1TNSListener

    OracleServiceORCL

2）打開命令行，使用 sqlplus nokia_user/oracle@202.206.0.233/orcl 命令登陸 oracle ，顯示以下：

 

C:\Documents and Settings\Administrator>sqlplus nokia_user/oracle@202.206.0.233/orcl

SQL*Plus: Release 11.2.0.1.0 Production on 星期五 12月 23 10:37:52 2011

Copyright (c) 1982, 2010, Oracle.  All rights reserved.

ERROR:
ORA-12541: TNS: 無監聽程序

在ORA-12541: TNS: 無監聽程序 錯誤下，不管是否在本地登陸都是會提示ORA-12541: TNS: 無監聽程序錯誤的

3）在命令行中，執行lsnrctl status

C:\Documents and Settings\Administrator>lsnrctl status

在這裏能夠看到監聽程序參數文件的位置

 

4）修改監聽程序參數文件

初次打開時，內容以下

# listener.ora Network Configuration File: C:\Program_Files\Oracle\DataBase_11G_R2\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:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\Program_Files\Oracle\DataBase_11G_R2\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:\Program_Files\Oracle\DataBase_11G_R2

修改成：

# listener.ora Network Configuration File: C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1)
      #(PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = orcl))
      (ADDRESS = (PROTOCOL = TCP)(HOST =202.206.0.233)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = C:\Program_Files\Oracle\DataBase_11G_R2

SID_NAME，KEY 的值修改成要訪問的oracle實例的名稱，HOST 修爲 oracle 服務器使用的地址

 

5）重啓listener,在命令行中依次執行 lsnrctl stop，lsnrctl start

C:\Documents and Settings\Administrator>lsnrctl stop
