本文介绍了解决Oracle数据库中ORA-12514错误的方法。通过修改listener.ora文件，添加服务名ORCL的相关配置，解决了无法通过服务名连接数据库的问题。

版本：11.2.0.1.0 - 64bit

本机安装Oracle后链接测试发现以下情况：

sqlplus scott/tiger 正常登陆

sqlplus scott/tiger@orcl 登陆失败，提示ORA-12514错误，应该是无法识别服务名ORCL

为此查阅资料，找到以下解决方案：

-------------------------------------------------------------------

找到oracle安装目录下listener文件：

原文件如下：

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = d:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:d:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
)

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

ADR_BASE_LISTENER = d:\app\Administrator

修改后如下：

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = d:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:d:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = d:\app\Administrator\product\11.2.0\dbhome_1)
(SID_NAME = ORCL)
)
)

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

ADR_BASE_LISTENER = d:\app\Administrator
