"hibernate.query.plan_parameter_metadata_max_size", planCacheMaxSize ); }So, we will vary the QueryPlanCache and the ParameterMetadata cache size from 1 to 100. When the plan cache size is 1, the queries are always going to be compiled while when the plan cache size is 100, the query...

We’ve already talked about plan reuse and how SQL Server finds a plan in cache. In this section, we’ll look at how SQL Server manages the size of plan cache, and how it determines which plans to remove if there is no room left in cache. Earlier, I discussed a few situations in ...
The cache size is either number of plans or GB size, so if you’re hitting the max number of plans but it’s only 4GB, then it would be because you maxed out the number of plan cache entries. Or am I misunderstanding what you’re seeing? Erin Reply Bojan Jekic says: May 23, ...

Monitor plan cache size and data cache size. In general, as more queries are run, the amount of memory used for data page caching should increase along with the amount of memory used for plan cache. However, as we saw previously when discussing plan cache size, in SQL Server 2005 prior ...
The plan cache is distinct from the data cache. In addition, there are other functionality-specific caches. As soon as the size of the plan cache reaches 50% of the buffer pool size, the next plan cache access decrements the ticks of all of the plans by 1 each. Notice that because th...
plan_cache_evict_interval 更新时间:2024-12-02 15:17:40 功能描述 plan_cache_evict_interval用于设置执行计划缓存的淘汰时间间隔。 属性说明 属性描述 参数类型Time 默认值5s 说明 该配置项从 V4.2.0 版本开始默认值由 1s 调整为 5s。 取值范围[0s, +∞) ...
plan_cache_low_watermark用于设置执行计划缓存占用内存的阈值,如果低于该阈值时将停止淘汰。 属性说明 属性描述 参数类型Capacity 默认值1500M,默认单位为 MB,配置时需说明单位。 取值范围[0,plan_cache_high_watermark) 是否可修改是,支持通过ALTER SYSTEM SET语句修改。
