死锁跟踪：6种跟踪死锁的方法总结

--  后台跟踪  
declare @rc int    
declare @traceid int          --跟踪分配的编号    
declare @options int          --TRACE_FILE_ROLLOVER=2/SHUTDOWN_ON_ERROR=4/TRACE_PRODUCE_BLACKBOX=8    
declare @tracefile nvarchar(500)--跟踪文件的存储路径    
declare @maxfilesize bigint   --跟踪文件的大小，单位是mb，默认5mb    
declare @endtime datetime     --停止跟踪的日期和时间,为NULL则表示一直跟踪    
declare @filecount int        --跟踪文件的数量,其值大于1,TRACE_FILE_ROLLOVER=2 时有效    
set @options = 2    
set @tracefile = N‘E:\BlockedTraceName‘    
set @maxfilesize = 20    
set @endtime = NULL  
set @filecount = 5    
    
--  exec @rc = sp_trace_create @TraceID output, 0, N‘InsertFileNameHere‘, @maxfilesize, NULL     
exec @rc = sp_trace_Create @TraceID output,@options,@tracefile,@maxfilesize,@endtime,@filecount    
if (@rc != 0) goto error    
  
-- Set the events  
declare @on bit  
set @on = 1  
exec sp_trace_setevent @TraceID, 148, 1, @on  
exec sp_trace_setevent @TraceID, 148, 12, @on  
exec sp_trace_setevent @TraceID, 148, 14, @on  
exec sp_trace_setevent @TraceID, 148, 26, @on  
  
-- Set the Filters  
declare @intfilter int  
declare @bigintfilter bigint  
  
-- Set the trace status to start  
exec sp_trace_setstatus @TraceID, 1  
  
-- display trace id for future references  
select TraceID=@TraceID  
goto finish  
  
error:   
select ErrorCode=@rc  
  
finish:

--查看跟踪记录

--查看是否死锁，确定死锁的的时间  
exec xp_readerrorlog 0,1,‘deadlock victim‘,NULL,‘2015-01-01‘,‘2015-01-10‘,‘ASC‘  
  
--按时间查看sqlserver日志，即为死锁信息  
exec xp_readerrorlog 0,1,NULL,NULL,‘2015-01-07 22:13:10‘,‘2015-01-07 22:13:11‘,‘ASC‘
