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();
}
}
