监听程序:LISTENER
选定协议：TCP
端口：1521
但还是不行，请问你是这样配置吗？还需要配置其他什么东西呢？请指教，谢谢。
解决方法：
1、如果是因为修改了NT的机器名，则把listener.ora文件中的host参数全部改为新的NT机器名，
重新启动OracleTNSListenr80服务即可。
例如:
LISTENER =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(Host = NT_Name)(Port = 1521))
(ADDRESS = (PROTOCOL = TCP)(Host = NT_Name)(Port = 1526))
)
2。使用监听器实用程序：LSNRCTL80.exe
3。检查监听器参数文件：c:\orant\NET80\admin\listener.ora
4。检查监听器日志文件：c:\orant\NET80\log\listener.log
5。Tnsnames.ora文件配置错误，重新配置。
6。检查client 端 Tnsnames.ora
