内容图文

操作系统为：SunOS 5.10数据库版本：Oracle RAC 11.2.0.3.0该主机上有2个库，一套RAC的节点1在上面，还有另外一个库，之所以使用

环境：
操作系统为：SunOS 5.10
数据库版本：Oracle RAC 11.2.0.3.0
该主机上有2个库，一套RAC的节点1在上面，还有另外一个库，之所以使用的是DB下的监听而没用GRID下的监听，是为了避免停掉CRS时影响另外一个库的使用。

故障现象：
数据库监听不定期出现异常 ,从应用tnsping数据库，时间花费很长甚至连不上

故障分析处理过程：

从应用主机tnsping如下：

racdb1_scenemon$tnsping racdb_new

从数据库服务器上查看监听状态：

$ lsnrctl status

LSNRCTL for Solaris: Version 11.2.0.3.0 - Production on 19-FEB-2014 15:45:58

Copyright (c) 1991, 2011, Oracle. All rights reserved.

TNS-12535: TNS:operation timed out
TNS-12560: TNS:protocol adapter error
TNS-00505: Operation timed out

将监听进程予以kill并重启监听：

$ ps -ef |grep tns

Too many open files意味着Maximum Number Of Open Files Per Process 达到了上限。因此listener hang住的原因可能是该limit设置过小，进一步查看硬件限制如下：
