解决ORA-12170:TNS connect timeout occurred问题

公司服务器周末要加硬盘，周一来后应用连不上了。报错如下报错： ORA-12170:TNS connect timeout occurred

第一反应是监听没开：

1. 测试了一下，连接超时没用ping 通

C:\Users\Administrator>tnsping brorcl

TNS Ping Utility for 64-bit Windows: Version 11.2.0.1.0 - Production on 15-6月 -2015 09:45:43

已使用的参数文件:

D:\oracle\product\11.2.0\dbhome_1\network\admin\sqlnet.ora

已使用 TNSNAMES 适配器来解析别名

尝试连接 (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.14.147.112)(PORT = 42525)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = brorcl)))
TNS-12535: TNS: 操作超时

2. 我登陆到远程服务器上，查看了一下监听的状态

C:\Documents and Settings\Administrator>lsnrctl status

LSNRCTL for 64-bit Windows: Version 11.2.0.1.0 - Production on 15-6月 -2015 09:52:54
