ms-sql数据库优化(转) 某个存储过程中先锁定表B,再锁定表A,这可能就会导致一个死锁。如果锁定顺序没有被预先详细的设计好,死锁很难被发现 46、通过SQL Server Performance Monitor监视相应硬件的负载 Memory: Page Faults / sec计数器如果该值偶尔走高,表明当时有线程竞争内存。如果持续很高,则内存可能是瓶颈。
将SQL Server max server memory 服务器配置选项配置为物理内存的 1.5 倍(虚拟内存大小设置的一半)。 7、增加服务器CPU个数;但是必须明白并行处理串行处理更需要资源例如内存。使用并行还是串行程是MsSQL自动评估选择的。单个任务分解成多个任务,就可以在处理器上运行。例如耽搁查询的排序、连接、扫描和GROUP BY字句同...
在 SQL Server 中,这个性能由 timestamp 数据类型提供,它是一个二进制数字,表示数据库中更改的相对顺序。每个数据库都有一个全局当前时间戳值:@@DBTS。每次以任何方式更改带有 timestamp 列的行时,SQL Server 先在时间戳列中存储当前的 @@DBTS 值,然后增加 @@DBTS 的值。如果某...
