Examples
The following example shows how to set all the CPUs on an instance of SQL Server to hard affinity.
Visual Basic
using System;
using Microsoft.SqlServer.Management.Smo;
namespace samples
{
class Program
{
static void Main(string[] args)
{
Server dbServer = new Server("(local)");
dbServer.AffinityInfo.Cpus[1].AffinityMask = true;
dbServer.AffinityInfo.AffinityType = AffinityType.Manual;
foreach (Cpu cpu in dbServer.AffinityInfo.Cpus)
cpu.AffinityMask = true;
dbServer.AffinityInfo.Alter();
}
}
}
Powershell
$dbServer = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$dbServer.AffinityInfo.AffinityType = [Microsoft.SqlServer.Management.Smo.AffinityType]'Manual'
foreach ($cpu In $dbServer.AffinityInfo.Cpus)
{
$cpu.AffinityMask = $True
$dbServer.AffinityInfo.Alter()
}
