ReplicationDatabase.EnabledTransPublishing Property

 

Applies To: SQL Server 2016 Preview

Gets or sets whether the database is enabled for transactional or snapshot publishing or not.

Namespace:   Microsoft.SqlServer.Replication
Assembly:  Microsoft.SqlServer.Rmo (in Microsoft.SqlServer.Rmo.dll)

public bool EnabledTransPublishing { get; set; }

Property Value

Type: System.Boolean

A Boolean value that specifies whether the database is enabled for transaction or snapshot publishing or not. If true, the database is enabled for transactional or snapshot publishing. If false, the database is not enabled for transactional or snapshot publishing.

The EnabledTransPublishing property can only be set by members of the sysadmin fixed server role.

The EnabledTransPublishing property can be retrieved by the sysadmin fixed server role on the server, by the db_owner fixed database role on the replication database, and by a user in the public access list (PAL) for a publication published from the replication database.

Setting EnabledTransPublishing is equivalent to executing sp_replicationdboption (Transact-SQL).

Getting EnabledTransPublishing is equivalent to executing sp_helpreplicationdboption (Transact-SQL).

Legacy Code Example

This example enables transactional and snapshot publishing on AdventureWorks.

			// 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);

				publicationDb.EnabledTransPublishing = true;
				publicationDb.EnabledMergePublishing = true;
			}
			catch (Exception ex)
			{
				// Implement appropriate error handling here.
				throw new ApplicationException("An error occured when installing distribution and publishing.", ex);
			}
			finally
			{
				conn.Disconnect();
			}

This example disables transactional and snapshot publishing on AdventureWorks.

			// Set the Distributor and publication database names.
			// Publisher and Distributor are on the same server instance.
			string publisherName = publisherInstance;
			string distributorName = publisherInstance;
			string distributionDbName = "distribution";
			string publicationDbName = "AdventureWorks2012";

			// Create connections to the Publisher and Distributor
			// using Windows Authentication.
			ServerConnection publisherConn = new ServerConnection(publisherName);
			ServerConnection distributorConn = new ServerConnection(distributorName);

			// Create the objects we need.
			ReplicationServer distributor =
				new ReplicationServer(distributorConn);
			DistributionPublisher publisher;
			DistributionDatabase distributionDb =
				new DistributionDatabase(distributionDbName, distributorConn);
			ReplicationDatabase publicationDb;
			publicationDb = new ReplicationDatabase(publicationDbName, publisherConn);

			try
			{
				// Connect to the Publisher and Distributor.
				publisherConn.Connect();
				distributorConn.Connect();

				// Disable all publishing on the AdventureWorks2012 database.
				if (publicationDb.LoadProperties())
				{

					{
						publicationDb.EnabledMergePublishing = false;

						publicationDb.EnabledTransPublishing = false;
					}
				}
				else
				{
					throw new ApplicationException(
						String.Format("The {0} database does not exist.", publicationDbName));
				}

				// We cannot uninstall the Publisher if there are still Subscribers.
				if (distributor.RegisteredSubscribers.Count == 0)
				{
					// Uninstall the Publisher, if it exists.
					publisher = new DistributionPublisher(publisherName, distributorConn);
					if (publisher.LoadProperties())
					{
						publisher.Remove(false);
					}
					else
					{
						// Do something here if the Publisher does not exist.

						// Do something here if the distribition DB does not exist.
						throw new ApplicationException(String.Format(
							"The distribution database '{0}' does not exist on {1}.",
							distributionDbName, distributorName));
					}

					// Uninstall the Distributor, if it exists.
					if (distributor.LoadProperties())
					{
						// Passing a value of false means that the Publisher 
						// and distribution databases must already be uninstalled,
						// and that no local databases be enabled for publishing.
						distributor.UninstallDistributor(false);
					}
					else
					{
						//Do something here if the distributor does not exist.
						throw new ApplicationException(String.Format(
							"The Distributor '{0}' does not exist.", distributorName));
					}
				}
				else
				{
					throw new ApplicationException("You must first delete all subscriptions.");
				}
			}
			catch (Exception ex)
			{
				// Implement appropriate error handling here.
				throw new ApplicationException("The Publisher and Distributor could not be uninstalled", ex);
			}
			finally

				publisherConn.Disconnect();
				distributorConn.Disconnect();
			}
