SQL Server エージェントでの自動管理タスクのスケジュール設定

例

提供されているコード例を使用するには、アプリケーションを作成するプログラミング環境、プログラミング テンプレート、およびプログラミング言語を選択する必要があります。詳細については、「Visual Studio .NET で Visual Basic SMO プロジェクトを作成する方法」または「Visual Studio .NET で Visual C# SMO プロジェクトを作成する方法」を参照してください。

1. プログラムで SQL Server エージェントを使用する場合、エージェント名前空間を修飾する Imports ステートメントを含める必要があります。アプリケーションの宣言の前、かつ他の Imports ステートメントの後に、次のようにステートメントを挿入します。

Imports Microsoft.SqlServer.Management.Smo

Imports Microsoft.SqlServer.Management.Common

Imports Microsoft.SqlServer.Management.Smo.Agent

Visual Basic での警告の作成

このコード例では、パフォーマンス条件によってトリガされる警告を作成しています。条件は、次の形式で指定する必要があります。

ObjectName|CounterName|Instance|ComparisionOp|CompValue

警告の通知にはオペレータが必要です。operator は Visual Basic キーワードであるため、Operator 型には角かっこが必要です。

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Define an Alert object variable by supplying the SQL Agent and the name arguments in the constructor.
Dim al As Alert
al = New Alert(srv.JobServer, "Test_Alert")

'Create the alert on the SQL Agent.
al.Create()

'Run the AddNotification method to specify the operator is notified when the alert is raised.

Visual Basic でプロキシ アカウントを使用することでユーザーがサブシステムにアクセスできるようにする

このコード例では、ProxyAccount オブジェクトの AddSubSystem メソッドを使用して、ユーザーが指定されたサブシステムにアクセスできるようにする方法を示します。

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Declare a JobServer object variable and reference the SQL Agent.
Dim js As JobServer
js = srv.JobServer
'Define a Credential object variable by supplying the parent server and name arguments in the constructor.
Dim c As Credential
c = New Credential(srv, "Proxy_accnt")
'Set the identity to a valid login represented by the vIdentity string variable. 
'The sub system will run under this login.
c.Identity = vIdentity
'Create the credential on the instance of SQL Server.
c.Create()
'Define a ProxyAccount object variable by supplying the SQL Agent, the name, the credential, the description arguments in the constructor.
Dim pa As ProxyAccount
pa = New ProxyAccount(js, "Test_proxy", "Proxy_accnt", True, "Proxy account for users to run job steps in command shell.")
'Create the proxy account on the SQL Agent.
pa.Create()
'Add the login, represented by the vLogin string variable, to the proxy account. 
pa.AddLogin(vLogin)
'Add the CmdExec subsytem to the proxy account. 
pa.AddSubSystem(AgentSubSystem.CmdExec)
'Now users logged on as vLogin can run CmdExec job steps with the specified credentials.
