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。

同时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


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. 解决办法

检查了监控vg的moniter脚本，发现也没有异常，而且脚本在其他库，压力都比较大的都不曾出问题。

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
                )

决定暂时将监控时长加大到90s，可以使用两种方法：

（1）可以修改main.cf，但需要重启VCS，无操作时间窗口

（2）命令动态修改

haconf -makerw

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

haconf -dump
