New Types of Replication New types of replications have been introduced in SQL Server 2005. The first of these is the Heterogeneous Replication which allows the publication of data from heterogeneous subscribers such as Oracle, DB2 using relevant ODBC drive and OLE DB provider. In SQL Server 2005 allows configuration of the snapshot and transaction replication without requiring additional software. The second type is the Snapshot replication from an oracle publisher. This requires the publisher to generate a set of data and the transfer of such data to the subscriber. When oracle is used the SQL Server connects to the Oracle database and retrieves the data without needing a change tracking or insertion of information into the Oracle database. Transactional replication requires that each transaction made to the data at the publisher is tracked, so that it can be replicated to subscribers. While configuring an Oracle publisher from the SQL Server triggers are added to replicate tables created in Oracle for each published table.

The concept of Peer to peer transactional replication is used to increase the server scale out

capabilities. All nodes within the system are treated as peers and can be updated

simultaneously. Each node has its own Log Reader Agent and Distribution Agent.

Therefore, a node can be taken offline for scheduled maintenance without impact on

performance and put online again and logs from other nodes can be applied to it.

HTTP Replication

SQL Server 2005 introduces Web synchronization for merge replication and provides the

user with the ability to replicate directly over an HTTP or HTTPS connection. This solution

 will be appreciated by mobile users. The Internet Information Services are used to transfer

data between the publisher and the subscriber and subscribers connect to a URL on the

 web server using authentication parameters configured in the subscription. The messages

sent are packaged as XML and encrypted using Secure Socket Layer for security. The IIS

communicates in a binary format with the publisher over a TCP/IP network connection.

Since HTTP replication is merge replication technology, updates can be made both to rows

at both the subscriber and publisher ends. Since the subscriber is mobile, the merge agent

runs on the subscriber and configures only pull subscriptions. The synchronization can be

configured to run continuously, on schedule or on demand. Subscription is initialized at the

subscriber end by a snapshot generated at the publisher and transferred to the subscriber.

In Web synchronization the snapshot is delivered as an attachment over HTTP.

Configuring Replication Using RM O

RMO can be used to create managed .NET applications that help in configuring and

maintaining replication in SQL Server 2005. RMO is implemented as a class within a .NET

assembly called Microsoft.sqlserver.rmo.dll. This assembly contains the Microsoft

SqlServer.Replication namespace.

Referencing the RMO and SMO libraries

RMO and SMO libraries can be referenced from the project created in Visual Studio.NET.

1. On the Project menu, click  Add Reference.

2. In the  Add Reference dialog box, click Microsoft.SqlServer.ConnectionInfo, hold

the CTRL key down, and click Microsoft.SqlServer.Replication .NET Programming

Interface. Click OK .

Creating a Subscription Using RMO

Replication can be configured using RMO. The typical tasks that will have to be performed

are importing the SMO and RMO namespaces, connecting to the subscriber and publisher

servers, listing existing subscribers for a publication and creating a new subscription for

In this module we have examined the enhancements made to replication services and the

different types of replications that have been introduced in SQL Server 2005. We have also

 briefly examined how replication can be configured using the options available in the SQL

Server 2005 version.

 This tutorial is part of a SQL Server 2005 Training tutorial series. Read it from the

 beginning and learn yourself.
