刷新**当前活动**将调用 **sp\_MSset\_current\_activity** 存储过程。 在定义该存储过程时，首先将 *lock\_timeout*变量设置为 5000 毫秒 (ms)。 然后，会创建两个全局临时表，它们针对下面的系统表在表级别发出 IX 锁，在键级别发出 X 锁：

*  **tempdb..sysobjects** 
 *  **tempdb..sysindexes** 
 *  **tempdb..syscolumns**

如果在 5000 毫秒 (ms) 内未将前面的锁授予该进程，则查询将停止，并出现“症状”一节中显示的错误信息。  
  
再刷新一次通常会成功。 但是，如果保持这两个锁的时间太长，则也会显示该错误信息。 如果执行 **sp\_lock** 存储过程，则可计算出哪个进程正在对 **dbid**2 (**tempdb**) 的对象 ID 1、2 和 3 保持锁定。

杀死锁：

/\*--处理死锁

查看当前进程,或死锁进程,并能自动杀掉死进程

因为是针对死的,所以如果有死锁进程,只能查看死锁进程  
 当然,你可以通过参数控制,不管有没有死锁,都只查看死锁进程

\--邹建 2004.4--\*/

/\*--调用示例

exec p\_lockinfo  
\--\*/  
create proc p\_lockinfo  
@kill\_lock\_spid bit=1,  --是否杀掉死锁的进程,1 杀掉, 0 仅显示  
@show\_spid\_if\_nolock bit=1 --如果没有死锁的进程,是否显示正常进程信息,1 显示,0 不显示
