另外,内存紧张也会导致RESOURCE_SEMAPHORE_QUERY_COMPILE的出现的概率增加,那么是否增加内存就有效解决RESOURCE_SEMAPHORE_QUERY_COMPILE等待事件呢?答案是否定的,但是能缓解。如下描述: This wait occurs when queries cannot be compiled due to the amount of compile memory currently available. This mostly occurs due...

当您尝试同时在 Microsoft SQL Server 2014 中执行多个大型查询时,某些查询可能会等待 RESOURCE_SEMAPHORE_QUERY_COMPILE。 即使服务器有足够的可用内存,仅一个查询需要的内存超过大网关阈值(由 DBCC MEMORYSTATUS 命令的输出提供)才能继续。注意这是一种预期行为。 但是,在大型批处理系统(如数据仓库)中,这可能会在多个...
When you try to execute multiple large queries at the same time in Microsoft SQL Server 2014, some queries may wait for RESOURCE_SEMAPHORE_QUERY_COMPILE. Only one query that requires more memory than the big gateway threshold (as provided by...

The RESOURCE_SEMAPHORE wait was the wait type for most of the transactions in addition to some page IO waits and the page IO waits were also due to memory pressure. >>Can it because of the query compile cache still holding to higher memory spec values , hence cause memory crunch ?
