释放Sql Server内存

  
  use master
    exec sp_configure 'show advanced options', 1
    reconfigure with OVERRIDE
    
    -- 先设置物理内存上限到一个比较低的值，但也不要太低
    exec sp_configure 'max server memory (MB)', 10240
    reconfigure with OVERRIDE
    
    -- 等待Sql server释放
    waitfor Delay '00:02:00'
    
    -- 还原原先的内存上限
    exec sp_configure 'max server memory (MB)', 40496
    reconfigure with OVERRIDE
    
    exec sp_configure 'show advanced options', 0

reconfigure with OVERRIDE

思路很简单就是动态的设置sql server的最多可用内存.
