1. 环境描写叙述

操作系统版本号：SUSE Linux Enterprise Server 10 sp2 (x86_64)

数据库版本号：Oracle 11.1.0.7.16

VCS版本号：5.1

2. 问题现象及分析

凌晨3:46左右。手机短信收到数据库异常告警。

（1）查看数据库alert日志

Sun Nov 16 03:46:51 2014

Sun Nov 16 03:51:52 2014

LGWR waiting for instance termination

并未发现较为明显的异常原因。

同一时候也查看了那个时间段的报告，发现数据库压力不大。也没有什么异常的SQL存在。

（2）检查OS资源使用

VCS引起的oracle数据库异常重新启动一例

系统资源使用正常。IO也不高。

（3）查看messages日志

原来是VCS出现了错误，监控vg超时了，这些错误信息在VCS的日志中也有记录。

3. 解决的方法

检查了监控vg的moniter脚本。发现也没有异常，并且脚本在其它库，压力都比較大的都不曾出问题。

当前的配置为：

        Application ora_vg (

                StartProgram = "/opt/BOSCO_ora/bin/vg_start.sh"

                StopProgram = "/opt/BOSCO_ora/bin/vg_stop.sh"

                CleanProgram = "/opt/BOSCO_ora/bin/vg_clean.sh"

                MonitorProgram = "/opt/BOSCO_ora/bin/vg_monitor.sh"

                MonitorInterval = 30

                MonitorTimeout = 30

                )

决定临时将监控时长加大到90s，能够使用两种方法：

（1）能够改动main.cf，但须要重新启动VCS，无操作时间窗体

（2）命令动态改动

haconf -makerw

hares -modify ora_vg MonitorTimeout 90   ## 调整监控时长为90s，默认是60s

haconf -dump
