示例

本例在分发器安装时创建分发数据库。它还支持在 AdventureWorks 数据库上进行合并和事务性发布。

// Set the server and database names
string distributionDbName = "distribution";
string publisherName = publisherInstance;
string publicationDbName = "AdventureWorks2012";

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();

    // Enable AdventureWorks2012 as a publication database.
    publicationDb = new ReplicationDatabase(publicationDbName, conn);
