参数

  • startNumaNodeId
    类型: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
    类型: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.
  • affinityMask
    类型:Microsoft.SqlServer.Management.Smo.NumaNodeAffinity
    The affinity mask value to set. The value must be one of the values listed for the NumaNodeAffinity. AffinityMask cannot be set to [E:Microsoft.SqlServer.Management.Smo.NumaNodeAffinity.Partial.]

示例

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

using System;
using System.Collections.Specialized;
using System.Data;
using Microsoft.SqlServer.Management.Smo;

namespace samples
{
    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();
        }
    }
}
