解决 ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务

速度太慢点击了一下优化，出现了 ORA-12514，搜索了解决方法记录一下，第一个基本服务就解决了。

转自：http://apps.hi.baidu.com/share/detail/19115407

PS：不晓得，大家有没有像我这样折腾，俺总喜欢关闭不是总用到的服务，等用到时再手动启动，此外经常更换ip地址

系统环境：Windows 2003 Ent R2 CHS 32bit，Oracle 11.2.0.1.0 R2

下面操作默认在安装Oralce数据库的服务器上运行。

1）确保Oracle 基本服务都已启动

    OracleDBConsoleorcl

    OracleOraDb11g_home1TNSListener

    OracleServiceORCL

2）打开命令行，使用 sqlplus nokia_user/oracle@202.206.0.233/orcl 命令登录 oracle ，显示如下：

C:Documents and SettingsAdministrator>sqlplus nokia_user/oracle@202.206.0.233/orcl

ERROR:
ORA-12541: TNS: 无监听程序

在ORA-12541: TNS: 无监听程序 错误下，无论是否在本地登录都是会提示ORA-12541: TNS: 无监听程序错误的

3）在命令行中，执行lsnrctl status

C:Documents and SettingsAdministrator>lsnrctl status

在这里可以看到监听程序参数文件的位置

4）修改监听程序参数文件

初次打开时，内容如下

# listener.ora Network Configuration File: C:Program_FilesOracleDataBase_11G_R2product11.2.0dbhome_1 etworkadminlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:Program_FilesOracleDataBase_11G_R2product11.2.0dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:Program_FilesOracleDataBase_11G_R2product11.2.0dbhome_1inoraclr11.dll")
    )
  )

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

ADR_BASE_LISTENER = C:Program_FilesOracleDataBase_11G_R2

修改为：

# listener.ora Network Configuration File: C:Program_FilesOracleDataBase_11G_R2product11.2.0dbhome_1 etworkadminlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = C:Program_FilesOracleDataBase_11G_R2product11.2.0dbhome_1)
      #(PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:Program_FilesOracleDataBase_11G_R2product11.2.0dbhome_1inoraclr11.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_FilesOracleDataBase_11G_R2

SID_NAME，KEY 的值修改为要访问的oracle实例的名称，HOST 修为 oracle 服务器使用的地址

5）重启listener,在命令行中依次执行 lsnrctl stop，lsnrctl start

C:Documents and SettingsAdministrator>lsnrctl stop
