使用SQL Server Management Studio 或 Azure Data Studio 连接到数据库引擎。 在标准栏上,选择“新建查询”。 将以下示例复制并粘贴到查询窗口中,然后选择“执行”。 此示例说明如何使用sp_configure将max degree of parallelism选项的值配置为16。 SQL复制 ...
To suppress parallel plan generation, set max degree of parallelism to 1. Set the value to a number from 1 to 32,767 to specify the maximum number of processor cores that can be used during a single query execution. If a value greater than the number of available processors ...
Describes configuring a policy to verify the value of max degree of parallelism for Policy-Based Management for SQL Server.
您可以使用 max degree of parallelism 选项来限制并行计划执行时所用的处理器数。 当SQL Server数据库在具有多个微处理器或 CPU 的计算机上运行时,它将为每个并行计划执行检测最佳并行度(即运行一个语句所使用的处理器数)。您可以使用 max degree of parallelism 选项来限制并行计划执行时所用的处理器数。如果默认...
Data-warehousing / Reporting server: 因为查询执行时间一般较长,建议设置“Maximum degree of Parallelism”(MAXDOP)为0。 这样大多数查询将会利用并行处理,执行时间较长的查询也会受益于多处理器而提高性能。 混合系统 Mixed System (OLTP & OLAP):这样环境会是一个挑战,必须找到正确的平衡点。一般采取了非常简单的...

Note that this can be set differently for each instance of SQL Server. So if you have multiple SQL Server instances in the same server, it is possible to specify a different Maximum DOP value for each one. --The max degree of parallelism option is an advanced option --and let you set...
maximum degree of parallelism (MaxDoP) cost threshold for parallelism (CTFP) Starting fromBigFix10.0.2, you can use the/checksqlserverparallelismBESAdmin command to check if the MaxDoP and CTFP settings of your database instance are configured appropriately, and to detect other issues described lat...

The maximum degree of parallelism is configured just like that of parallel queries. For more information, see Configure the max degree of parallelism (server configuration option).Note: Parallel DBCC checks should typically be enabled (default). The query processor reevaluates and automatically adju...
