https://www.cnblogs.com/wenBlog/p/5857252.html(后来发现的文章,并没有试验过)
https://www.cnblogs.com/zhijianliutang/p/4113911.html (以上三个链接中的文件路径书写方式均不对,看这个)
测试之后记录自己的使用过程及结果:
1.按以上第二种方法测试,执行代码报错
Procedure sp_trace_create, Line 1.The trace file path is not valid or not supported.//过程sp_trace_create,第1行。跟踪文件路径无效或不受支持
发现文件路径书写错误(我用的是SQL SERVER2008R2和SQL SERVER 2012,都试了),更改为“\”即可
2.生产过程中发生两次死锁,将xml格式数据粘贴出来

针对以上文件,如何分析,百度后发现以下说法:
1.victim-list没什么可分析的。
2.process-list中关于各个process的详细信息很重要。
3.再看process中的inputbuf。这个tag表明了process正在运行的语句,因此对于定位死锁非常重要。但这里有一个问题,比如上例中,inputbuf是一个存储过程,其中又嵌套了很多其他的存储过程,而我们需要在其中找出直接导致死锁的语句并优化,从而解决或减少死锁。自此我们已经有的信息是:导致死锁的语句由inputbuf中的语句调用,同时导致死锁的语句必定是对表MatchService的修改语句。如果存储过程很简单,到此DBA已经能够找到直接导致死锁的sql了,分析过程到此结束。而如果存储过程很复杂,则需要进一步分析。
4.现在再进一步考察tag, executionStack。executionStack表明了死锁发生时,由该process调用的,正在运行的所有sql。上例中有4条sql。同时仔细观察上例可以发生,两个process的executionStack是完全相同的,因此考察一个就可以了。另外,如果procname不为空则直接得到了sql,但上例中该tag为空。
我们可能还需要找出包含该sql的具体存储过程,然后进行优化。出了用sql查询外,推荐使用一个叫“SQL Search”的第三方工具,很方便,免费的。
针对以上四点,我个人首先认为是“PR_StationStatus”表发生了死锁(项目中insert into到某表,该表创建了触发器,触发器中有调用update PR_StationStatus表,并且是很多地方都对该表进行update,insert,select等操作,其中update操作最多)。
第二次自定义死锁跟踪代码:
--创建跟踪文件返回值 declare @rc int --创建一个跟踪句柄 declare @TraceID int --创建跟踪文件路径 declare @TraceFilePath nvarchar(500) set @TraceFilePath=N'E:\SQLTest\' --跟踪文件的大小 declare @maxfilesize bigint set @maxfilesize=5 --设置停止的时间 declare @EndTime datetime set @EndTime=null --设置系统默认的操作 declare @options int set @options=2 --设置默认滚动文件的数目 declare @filecount int set @filecount=5 --执行创建跟踪 exec @rc=sp_trace_Create @TraceID output,--跟踪ID @options, @TraceFilePath, @maxfilesize, @EndTime, @filecount if(@rc=0) select @TraceID --查看刚刚创建的跟踪 select * from sys.traces where id=2;--id:跟踪id -- 设置跟踪事件:死锁事件 declare @on bit,@TraceID int set @on = 1 ;set @TraceID = 2; --下述语句中的148指的是locks:deadlock graph事件(参见sys.trace_events),12指的是spid列(参见sys.trace_columns) exec sp_trace_setevent @TraceID, 148, 12, @on exec sp_trace_setevent @TraceID, 148, 11, @on exec sp_trace_setevent @TraceID, 148, 4, @on exec sp_trace_setevent @TraceID, 148, 14, @on exec sp_trace_setevent @TraceID, 148, 26, @on exec sp_trace_setevent @TraceID, 148, 64, @on exec sp_trace_setevent @TraceID, 148, 1, @on -- 启动跟踪 exec sp_trace_setstatus @TraceID, 1 --查看跟踪文件内容 select * from ::fn_trace_gettable('E:\SQLTest\.trc',1)
过程截图:
等待死锁记录产生....
第三次自定义死锁跟踪
上一次的定义跟踪在过了一周后,发现跟踪文件也没有增加记录,但生产问题一直存在,查询了系统跟踪信息后发现已经没有了。
百度后发现:数据库实例在重启后,自定义跟踪就会取消。
解决方案:创建master库存储过程,并设置为实例启动时自动执行存储过程
