分享今天在客户那里遇到的SQLSERVER连接超时以及我的解决办法
客户的环境：SQLSERVER2005，WINDOWS2003 SP2 32位
这次发生连接超时的时间是2013-8-5 21:34分
在2013-8-5 19:25分左右也发生过一次
下面的SQL ERRORLOG截取的是19:18分~22:08分时间段之内的关键日志！！！
这个问题昨天出现了一次，今天出现了两次，起初没有认真对待，认为重启一下机器就没事了
我认为是CPU占用高或者内存占用高或者磁盘读写高，因为客户的机器安装了360安全卫士，
当时客户反映360安全卫士报“磁盘读写高”
因为我当时看了任务管理器，windows日志，各项信息都很正常，CPU占用在30%左右，内存在800MB左右
360那里也没有看出磁盘读写特别高（注意：当时我是在客户重启了机器之后看的!!!!!!!!!!!!）

入手
谁知道今晚又出现第三次，使得我要从酒店又跑回客户那里
我去到客户那里第一时间先看windows日志和sql errorlog
由于在SQL ERRORLOG里看到很多想尝试登陆数据库而失败的日志，
而且看到Windows eventlog里有好几次SQL服务意外关闭
的记录，但是SQLSERVER是没有shutdown 电脑的SQL语句的，所以肯定不是外人所为
而且连接超时也不是经常出现，所以排除了黑客捣蛋的可能性（客户的电脑设置了防火墙，sa用户禁用，路由器只开了1433端口）
电脑也做了一些安全设置
不过SQLSERVER有停止Microsoft SQL server的命令
下面两个SQL语句都可以用来停止SQLSERVER
1 SHUTDOWN 2 SHUTDOWN WITH NOWAIT
不过如果运行上面两个语句，在SQL ERRORLOG里会有相应的日志记录的
1 2013-11-30 00:09:42.89 spid12s Service Broker manager has shut down. 2 2013-11-30 00:09:42.94 spid54 Server shut down by request from login JOE\Administrator. 3 2013-11-30 00:09:42.94 spid54 SQL Trace was stopped due to server shutdown.

1 2013-11-30 00:14:19.99 spid52 Server shut down by NOWAIT request from login JOE\Administrator. 2 2013-11-30 00:14:19.99 spid52 SQL Trace was stopped due to server shutdown. Trace ID = '2'.

2013-11-30 00:09:42.94 spid54 Server shut down by request from login JOE\Administrator.
2013-11-30 00:14:19.99 spid52 Server shut down by NOWAIT request from login JOE\Administrator.
通过SQL语句来shundownSQLSERVER在错误日志里会显示上面两条记录
但是这次的shutdown记录是
SQL Server is terminating because of a system shutdown.
----------------------------------华丽的分割线-------------------------------
再仔细分析
由于我们的应用系统其中一个是用delphi写的，而且用ODBC来连接SQLSERVER，而且这个应用
是一打开就马上open connection，直到退出这个应用为止，不像C# 执行完毕就close（）
所以如果这个应用断开与数据库的连接就会影响到客户的业务运行，当时操作系统弹出“超时对话框”的时候
点击我们的系统很慢几乎没有反应，响应很迟钝，我重启电脑，看一下windows日志
我在客户的机器里截了一些图片
再看一下SQL ERRORLOG
下面这个是重启电脑之后，SQLSERVER启动的SQLERRORLOG

--------------------------------华丽的分割线--------------------------------------------
方向
我认为连接超时就是跟GPOSDB_log的自动增长有关，先解决这个增长问题
看一下LDF文件的大小
由于GPOSDB这个数据库本来是运行在SQLSERVER2000上的，后来要升级到SQLSERVER2005
就用附加分离方法附加到SQL2005上，但是考虑到以后有可能将GPOSDB又运行在SQL2000上
所以没有把GPOSDB的数据库兼容级别设置为90（SQL2005），而且这个数据库已经用了3年多
所以22.5GB的事务日志文件大小不奇怪，但是数据量不多，mdf文件大小才大概26MB
因为这个数据库一直使用默认的设置，即默认的文件增长设置（按数据文件和事务日志文件大小的10%来增长）
而在《SQLSERVER企业级平台管理实践》里提到
设置数据库自动增长注意要点
要设置成按固定大小增长，而不能按比例 对于小的数据库，设置一次增长50MB到100MB，大的数据库，一次增长100MB到200MB
因为这个数据库才大概26MB的大小（mdf文件26MB），属于小型数据库，我就设置事务日志文件一次增长50MB
而数据文件大小的增长设置可以不用动
然后我就使用下面的SQL语句，截断事务日志，收缩事务日志文件，由于我不知道事务日志文件压缩多少
我就设置了收缩到10MB
1 --脚本 2 USE GPOSDB 3 GO 4 --截断日志 5 BACKUP LOG GPOSDB TO DISK='d:\gposdblogbackup2013-8-5.trn' with TRUNCATE_ONLY 6 GO 7 8 --查看一下数据库信息 9 EXEC sp_helpdb @dbname='gposdb' 10 GO 11 12 --收缩事务日志文件到10MB 13 DBCC SHRINKFILE(GPOSDB_log,10) 14 GO 15 16 --再查看一下数据库信息 17 EXEC sp_helpdb @dbname='gposdb' 18 GO
执行完SQL语句之后，再看一下事务日志文件的大小和数据库情况
----------------------------华丽的分割线-----------------------------------
关于另外的那两个错误
我的笔记本电脑里的SQLSERVER 也出现了下面两个SQL日志信息，所以本人觉得下面两个错误问题不大
2013-08-05 00:37:12.04 spid11s The current event was not reported to the Windows Events log. Operating system error = 31(连到系统上的设备没有发挥作用。). You may need to clear the Windows Events log if it is full.

而下面这个SQL日志信息我估计是当时掉电造成SQLSERVER terminating
2013-08-05 19:20:22.60 服务器 SQL Server is terminating because of a system shutdown. This is an informational message only. No user action is required.
-------------------------------华丽的分割线------------------------------
这个解决办法有没有效明天就知道了
因为客户的办公室那里电压不稳定，刚好UPS又坏了，经常停电，一停电电脑又关机了
我担心这样每天这样毫无防御地关机会影响到硬盘，电脑经常突然掉电硬盘又可能损坏了而造成上面的情况
明天用HDTUNE检查一下硬盘看一下有没有坏道
由于随笔是在酒店写的，所以格式就将就一下吧O(∩_∩)O
-------------------------------------华丽的分割线-------------------------
因为下面两个错误没有错误号，由于本人资历尚浅，希望知道下面两个错误的错误原因的可以告诉我一声
2013-08-05 00:37:12.04 spid11s The current event was not reported to the Windows Events log. Operating system error = 31(连到系统上的设备没有发挥作用。). You may need to clear the Windows Events log if it is full.

如有不对的地方，敬请拍砖O(∩_∩)O
---------------------------------------------------------
2013-8-6补充
今天早上我到客户那里做了2个事情
1：把数据文件自动增长设置为一次自动增长50MB（虽然只有25MB大小而且数据量不像事物日志文件那样猛增，
为保险起见还是设置一下比较好）
2：使用HDTUNE检查硬盘，完整扫描了一次硬盘之后发现没有坏道
看了一下事物日志文件，大小为75MB，而且观察了到现在为止还没有发生连接超时的情况
原因：我怀疑是SQLSERVER需要格式化的硬盘空间太大，因为每次增长10%，那么事物日志文件每次需要增长22.5GB*10%=2.25GB
而且客户的电脑配置比较低，估计因为SQLSERVER格式化的时候出现问题，30秒都没有格式化好这部分空间
Autogrow of file 'GPOSDB_log' in database 'GPOSDB' was cancelled by user or timed out after 31000 milliseconds
---------------------------------------------------------
2013-8-7补充
今天再看2013-8-6和2013-8-7这两天的Windows日志和SQL ERROR LOG，没有发现弹出“连接超时”对话框和'GPOSDB_log'事务日志文件
增长失败的日志信息
还有事务日志文件现在有250MB大小
证明事务日志文件增长了，而且增长还算顺利，从中也证明了我这个方法是有效的o(∩_∩)o
2013-11-21补充：
2013-08-05 22:05:43.46 登录 错误: 18456，严重性: 14，状态: 7。
http://blogs.msdn.com/b/apgcdsd/archive/2011/09/27/kerberos-ntlm-sql-server.aspx
当你看到Login failed for user
此时，SQL Server已经识别出了要求登录用户，但是由于SQL Server内部的安全相关的设置，登录操作没有成功。
我们常见的18456错误就属于这类错误： Error: 18456, Severity: 14, State: XX.
我们可以通过State:XX来判断到底是什么原因导致的授权失败。
但是，由于担心恶意的客户端可能通过state来猜测失败原因并采取相应手段来攻击服务器，State是不能返回客户端的。
它会被写入SQL的ERROELOG文件。
失败state对应的原因：
1 通用错误
2 远程登录的登录在服务器中不存在
3，4 解密内存中加密的密码失败
5 SQL登录不存在
6 连接的SQL登录不符合登录类型列表
7 登录功能关闭
8 密码不符合
9密码不可用（登录时正在修改密码）
10 账户策略验证失败
如果以下密码策略检查评估返回假：
（1）登录成功
（2）密码已过期
（3）用户需要更改密码
然后我们设置登录状态，并返回一个失败state10
11 windows验证没有被授权可以连接
12 SQL验证没有被授权可以连接
13 服务器暂停，禁止所有登陆
14 登录不能用于此连接的接口类型
15 连接字符串中指定的数据库无效
16个默认数据库是无效的
17默认语言为无效
18这种登录类型密码不能改变
19无法解密加密的内存中的新密码
