SQLSERVER errorlog讲解
SQLSERVER errorlog讲解
很多时候诊断SQLSERVER问题都需要看SQLSERVER的错误日志
日志里面很多内容没有书本专门讲解，今天我就讲一下，可能里面的日志信息是从我个人的机器
里抓出来的，跟大家的机器环境会有所不同，但是SQLSERVER启动部分的日志大家都是一样的
特别的说一下：2013-02-12 17:53:29.29 spid29s
这些spid指的是SQLSERVER内部的进程，因为SQLSERVER内部有SQL OS，所以称呼他自己内部的线程为“进程”
所以在Windows的任务管理器里是看不到这些“进程ID的”的，这些进程ID也会跟会话关联的，例如你在
SSMS里新建一个查询，SQLSERVER就会新建一个会话ID（SPID），这些“进程”可以kill的
1 KILL spid --相应的spid
相当于在cmd下运行：TASKKILL notepad.exe（进程ID）
不过这些kill命令是发给SQLSERVER去执行
在启动的时候，SQLSERVER会创建很多线程来进行初始化数据库或者其他工作，所以会看到下面的，但是spid会不同

就这麽多了，SQL ErrorLog不会很多，所以有时候遇到SQL问题先查找SQL ErrorLog里的记录会比较好
当然了，在SSMS里也能看到SQL ErrorLog，SSMS里还包括筛选和搜索功能，但是有时候如果连SQLSERVER服务都启动不了
那只能到SQL ErrorLog的目录里面，用记事本或者其他编辑器打开找问题原因了
