規劃SQL Server EXPRESS的緩存大小。

Question

我在我們的一些服務器上使用SQL EXPRESS。它的內存限制爲1.5GB。如何在SQL Express中爲每個數據庫找到計劃緩存大小？

Answer 1

由於沒有人回答....

SELECT SUM(size_in_bytes) * 1.0/POWER(1024, 2) PlanCacheSize FROM sys.dm_exec_cached_plans; 
go 

SELECT objtype AS [CacheType] 
     , count_big(*) AS [Total Plans] 
     , sum(cast(size_in_bytes as decimal(18,2)))/1024/1024 AS [Total MBs] 
     , avg(usecounts) AS [Avg Use Count] 
     , sum(cast((CASE WHEN usecounts = 1 THEN size_in_bytes ELSE 0 END) as decimal(18,2)))/1024/1024 AS [Total MBs - USE Count 1] 
     , sum(CASE WHEN usecounts = 1 THEN 1 ELSE 0 END) AS [Total Plans - USE Count 1] 
FROM sys.dm_exec_cached_plans 
GROUP BY objtype 
ORDER BY [Total MBs - USE Count 1] DESC 
go
