ReplicationDatabase Class

レプリケーション トポロジのパブリケーション データベースまたはサブスクリプション データベースを表します。

名前空間: Microsoft.SqlServer.Replication
アセンブリ: Microsoft.SqlServer.Rmo (microsoft.sqlserver.rmo.dll 内)

構文

'宣言
Public NotInheritable Class ReplicationDatabase
    Inherits ReplicationObject
public sealed class ReplicationDatabase : ReplicationObject
public ref class ReplicationDatabase sealed : public ReplicationObject
public final class ReplicationDatabase extends ReplicationObject
public final class ReplicationDatabase extends ReplicationObject

解説

ReplicationDatabase を使用して、パブリケーションまたはサブスクリプション データベースを表すことができます。ReplicationDatabase を使用しても、master、tempdb、msdb、model などのシステム データベースを表すことはできません。ディストリビューション データベースは、DistributionDatabase によって表されます。

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。

継承階層

使用例

この例では、ディストリビュータをインストールするときにディストリビューション データベースを作成します。また、AdventureWorks データベースでのマージとトランザクション パブリッシングを有効化します。

// Set the server and database names
string distributionDbName = "distribution";
string publisherName = publisherInstance;
string publicationDbName = "AdventureWorks";

DistributionDatabase distributionDb;
ReplicationServer distributor;
DistributionPublisher publisher;
ReplicationDatabase publicationDb;

// Create a connection to the server using Windows Authentication.
ServerConnection conn = new ServerConnection(publisherName);

try
{
    // Connect to the server acting as the Distributor 
    // and local Publisher.
    conn.Connect();

    // Define the distribution database at the Distributor,
    // but do not create it now.
    distributionDb = new DistributionDatabase(distributionDbName, conn);
    distributionDb.MaxDistributionRetention = 96;
    distributionDb.HistoryRetention = 120;

    // Set the Distributor properties and install the Distributor.
    // This also creates the specified distribution database.
    distributor = new ReplicationServer(conn);
    distributor.InstallDistributor((string)null, distributionDb);

    // Set the Publisher properties and install the Publisher.
    publisher = new DistributionPublisher(publisherName, conn);
    publisher.DistributionDatabase = distributionDb.Name;
    publisher.WorkingDirectory = @"\\" + publisherName + @"\repldata";
    publisher.PublisherSecurity.WindowsAuthentication = true;
    publisher.Create();
