Параметры

  • startNumaNodeId
    Тип: System. . :: . .Int32
    An int from 0 to Count -1 that specifies the beginning of the range of NUMA nodes. If startIndex is not within the valid range, the following exception is returned: Specified argument was out of the range of valid values. Parameter name: startIndex.
  • endNumaNodeId
    Тип: System. . :: . .Int32
    An int that specifies the endIndex of the range. endIndex must be greater than or equal to startindex and less than [P:Microsoft.SqlServer.Management.Smo.NumaNodeCollection.Count.]
    If endIndex is not within the valid range, the following exception is returned: Specified argument was out of the range of valid values. Parameter name: endIndex.
    If endIndex is less than startIndex, the following exception is returned: The specified range of CPUs is not valid. The value for startIndex must be less than the value for endIndex.

The following example shows how to set the affinity for each NUMA node on an instance of SQL Server.

{
    class Program
    {
        static void Main(string[] args)
        {
            Server dbServer = new Server("(local)");
            dbServer.AffinityInfo.AffinityType = AffinityType.Manual;
            dbServer.AffinityInfo.NumaNodes.SetAffinityToRange(0,
                dbServer.AffinityInfo.NumaNodes.Count - 1,
                NumaNodeAffinity.Full);
            dbServer.AffinityInfo.Alter();
        }
    }
