使用模板:TSQL_Locks
事件选择:Deadlock graph,lock:DeadLock等等都可以,用默认的就行
或用標記通過SQL Server Profiler查死鎖信息:
啟動SQL Server Profiler——連接實例——事件選取範圍——顯示所有事件
選擇項:
TSQL——SQL:StmtStarting
Locks——Deadlock graph(這是SQL2005新增事件,生成包含死鎖信息的xml值)
——Lock:DeadlockChain 死鎖鏈中的進程產生該事件,可標識死鎖進程的ID並跟蹤操作
——Lock:Deadlock 該事件發生了死鎖

定时调用又怕因为它引起死锁或其他的问题~
因为是在正式服务器上,出了问题就大条了~
如果有deadlock是不是会自己弹出来啊?
如果想看deadlock的历史记录怎么查啊?
查看已经开启的traceflag 用 dbcc tracestatus
关闭这个traceflag 用dbcc traceoff(1222,-1) 这样又不记录死锁了。
