LSNRCTL for Linux: Version 11.1.0.7.0 - Production on 17-JUN-2014 18:15:47

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=wdatest11)(PORT=1521))) ## 到这里，hang住了，一直没有响应

TNS Ping Utility for Linux: Version 11.2.0.3.0 - Production on 17-JUN-2014 17:53:20
Copyright (c) 1997, 2011, Oracle. All rights reserved.
Used parameter files:
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.xxx)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = sms)))
OK (14760 msec) ## 可见响应也是非常慢的。
最后检查DNS配置时，发现有：
localhost:cat /etc/resolv.conf
nameserver x.x.x.x
系统配置有DNS，这是内网主机，根本用不到DNS，所以把这个DNS去掉后恢复正常。
