在 SMO 中配置 SQL Server

在 SMO 中,Information 对象、Settings 对象、UserOptions 对象和 Configuration 对象存储有关 Microsoft SQL Server 实例的设置和信息。

SQL Server 具有许多描述已安装的实例的行为的属性。这些属性描述了启动选项、服务器默认值、文件和目录、系统和处理器信息、产品和版本、连接信息、内存选项、语言和排序规则选择以及身份验证模式。

SQL Server 配置

Information 对象属性包含 SQL Server 实例的相关信息,例如处理器和平台。

Settings 对象属性包含 SQL Server 实例的相关信息。除邮件配置文件和服务器帐户之外,还可以修改默认的数据库文件和目录。这些属性在连接持续时间内一直保留。

UserOptions 对象属性包含与算术、ANSI 标准和事务相关的当前连接行为的相关信息。

还存在由 Configuration 对象表示的一组配置选项。它包含表示可通过 sp_configure 存储过程进行修改的选项的一组属性。诸如**“优先级提升”“恢复间隔”“网络数据包大小”**等选项用于控制 SQL Server 实例的性能。其中的许多选项可以进行动态更改,但在某些情况下,其值需要先配置,在重新启动 SQL Server 实例后才发生更改。

每个配置选项都对应一个 Configuration 对象属性。使用 ConfigProperty 对象,可以修改全局配置设置。许多属性都有最大值和最小值,这些值也存储为 ConfigProperty 属性。这些属性需要使用 Alter 方法来提交对 SQL Server 实例的更改。

Configuration 对象中的所有配置选项都必须由系统管理员进行更改。

示例

对于下列代码示例,您必须选择编程环境、编程模板和编程语言才能创建应用程序。有关详细信息,请参阅如何在 Visual Studio .NET 中创建 Visual Basic SMO 项目如何在 Visual Studio .NET 中创建 Visual C# SMO 项目

在 Visual Basic 中修改 SQL Server 配置选项

此代码示例说明如何在 Visual Basic .NET 中更新配置选项。它还检索并显示指定配置选项的最大值和最小值的相关信息。最后,程序会通知用户是否已进行了动态更改,或者是否存储了更改直到重新启动 SQL Server 实例后再予以应用。

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Display all the configuration options.
Dim p As ConfigProperty
For Each p In srv.Configuration.Properties
    Console.WriteLine(p.DisplayName)
Next
Console.WriteLine("There are " & srv.Configuration.Properties.Count.ToString & " configuration options.")
'Display the maximum and minimum values for ShowAdvancedOptions.
Dim min As Integer
Dim max As Integer
min = srv.Configuration.ShowAdvancedOptions.Minimum
max = srv.Configuration.ShowAdvancedOptions.Maximum
Console.WriteLine("Minimum and Maximum values are " & min & " and " & max & ".")
'Modify the value of ShowAdvancedOptions and run the Alter method.
srv.Configuration.ShowAdvancedOptions.ConfigValue = 0
srv.Configuration.Alter()
'Display when the change takes place according to the IsDynamic property.
If srv.Configuration.ShowAdvancedOptions.IsDynamic = True Then
    Console.WriteLine("Configuration option has been updated.")
Else
    Console.WriteLine("Configuration option will be updated when SQL Server is restarted.")
End If

在 Visual Basic 中修改 SQL Server 设置

此代码示例显示 InformationSettings 中有关 SQL Server 实例的信息,并修改 SettingsUserOptions 对象属性中的设置。

在此示例中,UserOptions 对象和 Settings 对象都有一个 Alter 方法。您可以分别运行这两个对象的 Alter 方法。

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Display information about the instance of SQL Server in Information and Settings.
Console.WriteLine("OS Version = " & srv.Information.OSVersion)
Console.WriteLine("State = " & srv.Settings.State.ToString)
'Display information specific to the current user in UserOptions.
Console.WriteLine("Quoted Identifier support = " & srv.UserOptions.QuotedIdentifier)
'Modify server settings in Settings.

srv.Settings.LoginMode = ServerLoginMode.Integrated
'Modify settings specific to the current connection in UserOptions.
srv.UserOptions.AbortOnArithmeticErrors = True
'Run the Alter method to make the changes on the instance of SQL Server.
srv.Alter()

在 Visual C# 中修改 SQL Server 设置

此代码示例显示 InformationSettings 中有关 SQL Server 实例的信息,并修改 SettingsUserOptions 对象属性中的设置。

在此示例中,UserOptions 对象和 Settings 对象都有一个 Alter 方法。您可以分别运行这两个对象的 Alter 方法。

//Connect to the local, default instance of SQL Server.

{
            Server srv = new Server();
            //Display all the configuration options. 

            foreach (ConfigProperty p in srv.Configuration.Properties)
            {
                Console.WriteLine(p.DisplayName);
            }
            Console.WriteLine("There are " + srv.Configuration.Properties.Count.ToString() + " configuration options.");
            //Display the maximum and minimum values for ShowAdvancedOptions. 
            int min = 0;
            int max = 0;
            min = srv.Configuration.ShowAdvancedOptions.Minimum;
            max = srv.Configuration.ShowAdvancedOptions.Maximum;
            Console.WriteLine("Minimum and Maximum values are " + min + " and " + max + ".");
            //Modify the value of ShowAdvancedOptions and run the Alter method. 
            srv.Configuration.ShowAdvancedOptions.ConfigValue = 0;
            srv.Configuration.Alter();
            //Display when the change takes place according to the IsDynamic property. 
            if (srv.Configuration.ShowAdvancedOptions.IsDynamic == true)
            {
                Console.WriteLine("Configuration option has been updated.");
            }
            else
            {
                Console.WriteLine("Configuration option will be updated when SQL Server is restarted.");
            }
        }

$srv = get-item default

#Display information about the instance of SQL Server in Information and Settings.
"OS Version = " + $srv.Information.OSVersion
"State = "+ $srv.Settings.State.ToString()

#Display information specific to the current user in UserOptions.
