Dim value As IProcessSecurityContext

value = instance.SnapshotGenerationAgentProcessSecurity

public IProcessSecurityContext SnapshotGenerationAgentProcessSecurity { get; }

説明

SnapshotGenerationAgentProcessSecurity は読み取り専用プロパティです。返された IProcessSecurityContext オブジェクトのプロパティを使用して、エージェントのセキュリティ コンテキストを設定する必要があります。エージェントによる接続と、これらの接続に必要な権限の詳細については、「レプリケーション エージェントのセキュリティ モデル」を参照してください。

SnapshotGenerationAgentProcessSecurity プロパティを取得できるのは、パブリッシャ側の固定サーバー ロール sysadmin のメンバ、またはパブリケーション データベースの固定データベース ロール db_owner のメンバだけです。

返された IProcessSecurityContext オブジェクトのプロパティを設定できるのは、パブリッシャ側の固定サーバー ロール sysadmin のメンバ、またはパブリケーション データベースの固定データベース ロール db_owner のメンバだけです。

SnapshotGenerationAgentProcessSecurity プロパティを取得すると、sp_helppublication_snapshot (Transact-SQL) を実行したのと同じことになります。

返された IProcessSecurityContext オブジェクトのプロパティを設定すると、sp_addpublication_snapshot (Transact-SQL) および sp_changepublication_snapshot (Transact-SQL) を実行したのと同じことになります。

SnapshotGenerationAgentProcessSecurity プロパティは、SQL Server 2005 でのみ使用できます。

セキュリティに関する注意セキュリティに関する注意

可能であれば、実行時にセキュリティ資格情報の入力を求めるメッセージをユーザーに対して表示します。資格情報を格納する必要がある場合は、Windows .NET Framework で提供される cryptographic services を使用します。

この名前空間、クラス、またはメンバは、.NET Framework 2.0 でのみサポートされています。
