속성

	이름	설명
	AffinityType	Gets or sets the affinity type of the AffinityInfoBase. (AffinityInfoBase에서 상속됨)
	Cpus	The Cpus member is a collection that represents the CPU settings for all CPUs on an Instance of SQL Server.
	NumaNodes	Gets a collection that contains the NUMA node settings. (AffinityInfoBase에서 상속됨)
	Parent	This gets the parent object of the AffinityInfo object. This value is the same as the Server object that contains the AffinityInfo member.

주의

To get AffinityInfo object properties, users can be a member of the public fixed server role.

To set any AffinityInfo object properties and run the Alter method, users must have ALTER permission on the database.

To create a AffinityInfo object, users must have ALTER ANY APPLICATION role permission on the parent database.

To drop an AffinityInfo object, users must be the owner of the application role or have ALTER ANY APPLICATION role permission on the parent database.

To grant, deny, and revoke permission on the AffinityInfo object, users must have CONTROL permission on the application role.

This example shows you how to set all of the CPU’s on an instance of SQL Server to hard affinity.

C#

using System;
using Microsoft.SqlServer.Management.Smo;

namespace samples
{
    class Program
    {
        static void Main(string[] args)
        {
            Server dbServer = new Server("(local)");
            dbServer.AffinityInfo.AffinityType = AffinityType.Manual;

            foreach (Cpu cpu in dbServer.AffinityInfo.Cpus)
                cpu.AffinityMask = true;

            dbServer.AffinityInfo.Alter();
        }
    }
}

Powershell

//Create the server. 
$dbServer = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")

//Set the Affinity Type
$dbServer.AffinityInfo.AffinityType = [Microsoft.SqlServer.Management.Smo.AffinityType]'Manual'

//Set each CPU to Hard affinity and update
foreach ($cpu In $dbServer.AffinityInfo.Cpus)
{
   $cpu.AffinityMask = $True
   $dbServer.AffinityInfo.Alter() 
}

스레드 보안

이 유형의 모든 공용 static(Visual Basic에서는 Shared) 멤버는 스레드로부터 안전합니다. 인스턴스 멤버는 스레드로부터의 안전성이 보장되지 않습니다.
