Esempi

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() 
}
