Heterogeneous Database Replication
SQL Server supports the following heterogeneous scenarios for transactional and snapshot replication:
Publishing data from SQL Server to non-SQL Server Subscribers.
Publishing data to and from Oracle has the following restrictions:
|2016 or earlier||2017 or later|
|Replication from Oracle||Only support Oracle 10g or earlier||Only support Oracle 10g or earlier|
|Replication to Oracle||Up to Oracle 12c||Not supported|
Heterogeneous replication to non-SQL Server subscribers is deprecated. Oracle Publishing is deprecated. To move data, create solutions using change data capture and SSIS.
This feature is in maintenance mode and may 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.
Publishing Data from Oracle
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. This feature requires Oracle version 10G or earlier. Publishing data from Oracle is ideal for the following scenarios:
|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.
Publishing Data to Non-SQL Server Subscribers
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.
