场景1:user connection配置了1500,数据库日志里面发现报错连接用完,需要定位是哪个机器或用户产生了大量连接 SQL语句: select * from (select b.name,a.hostname,a.program_name,count(*) counts from master..sysprocesses a,数据库1..sysusers b where a.suid=b.suid group by name,hostname,program_name union select b.name,a.hostname,a.program_name,count(*) counts from master..sysprocesses a,数据库2..sysusers b where a.suid=b.suid group by name,hostname,program_name ) tmp order by counts desc 场景2:查看数据库中运行时间较长的语句 SQL:select datediff(mi,starttime, getdate()) as time , * from master..syslogshold 场景3:查看某个参数的配置 方法一:sp_confiugre "参数名" 方法二:使用下面SQL语句进行查询: select b.name, c.value,c.memory_used, c.minimum_value, c.maximum_value, c.defvalue,c.unit from master.dbo.sysconfigures b, master.dbo.syscurconfigs c where b.config*=c.config and parent!=19 and b.config > 100 and name like '%参数名片段%' order by name  场景4:查看参数配置及历史使用情况 --全部配置: sp_monitorconfig 'all' --单个参数: sp_monitorconfig "参数名" 场景5:查看存储过程使用内存情况 dbcc traceon(3604) dbcc memusage dbcc traceoff(3604)
