20.6. Replication Management Objects (RMO)

Replication Management Objects, or RMO, is a new .NET object model that replaces the replication portion of the COM-based Distributed Management Objects (DMO) object model that was used in SQL Server 2000 and earlier. You can think of RMO as being something of a companion to SQL Management Objects (SMO), which we discuss extensively in Chapter 25.

RMO gives you programmatic access to any portion of your replication creation and configuration using any .NET language. Examples of RMO use would be automating operations such as:

• Creating and configuring a publication — You can make use of the ReplicationDatabase as well as the TransPublication or MergePublication objects to define publications.

• Adding and removing articles — The TransArticle object supports the addition and removal of articles within your publication. In addition, you can add column filters or add a FilterClause property to limit what rows are replicated.

• Republishing your snapshot

These are just some more everyday use kinds of examples. RMO is, however, capable of creating, modifying or deleting any part of the replication process.

RMO can be utilized in Visual Studio by adding a reference to the Microsoft.SqlServer.Replication .NET Programming Interface library. You then point your include, imports, or using directives to Microsoft.SqlServer.Replication. As with any of the management libraries that support SQL Server, you will also need to have a reference to the Microsoft.SqlServer.ConnectionInfo ...
