·SQL Server进程阻塞的检查和解决办法 -|cloudy 发表于 2007-4-14 14:18:00 |
查看阻塞相关的进程以及该进程正在执行的sql语句:
create procedure sp_who_lock as begin declare @spid int,@bl int, @intTransactionCountOnEntry int, @intRowcount int, @intCountProperties int, @intCounter int create table #tmp_lock_who ( id int identity(1,1), spid smallint, bl smallint) IF @@ERROR<>0 RETURN @@ERROR insert into #tmp_lock_who(spid,bl) select 0 ,blocked from (select * from sysprocesses where blocked>0 ) a where not exists(select * from (select * from sysprocesses where blocked>0 ) b where a.blocked=spid) union select spid,blocked from sysprocesses where blocked>0 IF @@ERROR<>0 RETURN @@ERROR -- 找到临时表的记录数 select @intCountProperties = Count(*),@intCounter = 1 from #tmp_lock_who IF @@ERROR<>0 RETURN @@ERROR if @intCountProperties=0 select '现在没有阻塞信息' as message -- 循环开始 while @intCounter <= @intCountProperties begin -- 取第一条记录 select @spid = spid,@bl = bl from #tmp_lock_who where Id = @intCounter begin if @spid =0 select '引起数据库阻塞的是: '+ CAST(@bl AS VARCHAR(10)) + '进程号,其执行的SQL语法如下' else select '进程号SPID:'+ CAST(@spid AS VARCHAR(10))+ '被' + '进程号SPID:'+ CAST(@bl AS VARCHAR(10)) +'阻塞,其当前进程执行的SQL语法如下' DBCC INPUTBUFFER (@bl ) end -- 循环指针下移 set @intCounter = @intCounter + 1 end
drop table #tmp_lock_who return 0 end GO
用来结束阻塞的进程:
--结束SQL阻塞的进程%%%%%%%%%%%%%%%%%%%%%% create procedure sp_Kill_lockProcess as begin SET NOCOUNT ON declare @spid int,@bl int, @intTransactionCountOnEntry int, @intRowcount int, @intCountProperties int, @intCounter int, @sSql nvarchar (200) create table #tmp_lock_who ( id int identity(1,1), spid smallint, bl smallint) IF @@ERROR<>0 RETURN @@ERROR insert into #tmp_lock_who(spid,bl) select 0 ,blocked from (select * from sysprocesses where blocked>0 ) a where not exists ( select * from (select * from sysprocesses where blocked>0 ) b where a.blocked=spid ) union select spid,blocked from sysprocesses where blocked>0 IF @@ERROR<>0 RETURN @@ERROR -- 找到临时表的记录数 select @intCountProperties = Count(*),@intCounter = 1 from #tmp_lock_who IF @@ERROR<>0 RETURN @@ERROR while @intCounter <= @intCountProperties begin -- 取第一条记录 select @spid = spid,@bl = bl from #tmp_lock_who where Id = @intCounter begin if @spid =0 begin set @sSql='kill ' + CAST(@bl AS VARCHAR(10)) exec sp_executesql @sSql end end -- 循环指针下移 set @intCounter = @intCounter + 1 end drop table #tmp_lock_who SET NOCOUNT OFF return 0 end
