公司服務器周末要加硬盤，周一來后應用連不上了。報錯如下 報錯： ORA-12170:TNS connect timeout occurred 

第一反應是監聽沒開：

1. 測試了一下， 連接超時沒用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

已使用的參數文件:

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

已使用 TNSNAMES 適配器來解析別名

嘗試連接 (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.14.147.112)(PORT = 42525)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = brorcl)))
TNS-12535: TNS: 操作超時

2. 我登陸到遠程服務器上，查看了一下監聽的狀態

C:/Documents and Settings/Administrator>lsnrctl status
