Heterogeneous Database Replication

SQL Server 2012 supports the following heterogeneous scenarios for transactional and snapshot replication:

  • Publishing data from Oracle to SQL Server.

  • Publishing data from SQL Server to non-SQL Server Subscribers.

Heterogeneous replication to non-SQL Server subscribers is deprecated. Oracle Publishing is deprecated. To move data, create solutions using change data capture and SSIS.

Caution note Caution

This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

You can use SQL Server to publish data from Oracle with most of the same features and ease-of-use as SQL Server snapshot and transactional replication. Publishing data from Oracle is ideal for the following scenarios:

Scenario

Description

Microsoft .NET Framework application deployments

Develop with Microsoft Visual Studio and SQL Server while operating on data replicated from a non-SQL Server database.

Data warehousing staging servers

Keep SQL Server staging databases synchronized with a non-SQL Server database.

Migration to SQL Server

Test your application in real time against SQL Server while replicating the source system's changes. Switch to SQL Server when satisfied with the migration.

For more information, see Oracle Publishing Overview.

The following non-SQL Server databases are supported as Subscribers to snapshot and transactional publications:

  • Oracle for all platforms that Oracle supports.

  • IBM DB2 for AS400, MVS, Unix, Linux, and Windows.

For more information, see Non-SQL Server Subscribers.
