已使用的参数文件:
D:\app\Administrator\product\11.2.0\client_1\network\admin\sqlnet.ora

已使用 EZCONNECT 适配器来解析别名
尝试连接 (DESCRIPTION=(CONNECT_DATA=(SERVICE_NAME=))(ADDRESS=(PROTOCOL=TCP)(HOST
=10.64.52.20)(PORT=1521)))

速度非常慢  基本上没反应 。

同时，监听无响应。

数据库通过sqlplus / as sysdba能够正常登录，通过sqlplus system/password@orcl 无法登录。所以基本上可以确定是监听程序出现问题。

于是检查listener日志，在D:/app/Administrator/diag/tnslsnr/orcl/listener/trace下发现listner.log 已达4G。于是删除listerner.log日志，重启listener,一切恢复正常。

使用tnsping返回时间10msec。

为了避免以后再出现类似的情况，可以在listener.ora中加入

LOGGING_LISTENER = OFF

重启listner,oracle将不再产生listener.log。
