ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

今天装了11G 的oracle 数据库库 登陆的时候 报上面错误 网上好多回答，我的是11G 的。 下面是解决方法，是配置问题

首先找到 E:\app\wen\product\11.2.0\dbhome_1\NETWORK\ADMIN 下面的listerner.ora 文件 用文本编辑器打开

然后修改为下面

# listener.ora Network Configuration File: E:\app\wen\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 = E:\app\wen\product\11.2.0\dbhome_1)

)

(SID_DESC =

(GOLBAL_DBNAME= orcl)

(ORACLE_HOME = E:\app\wen\product\11.2.0\dbhome_1)

(SID_NAME=orcl)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.118.7.191)(PORT = 1521))

)

)

ADR_BASE_LISTENER = E:\app\wen

重启监听程序 试试 就ok
