[!INCLUDE SQL Server]
[!INCLUDEssNoVersion] supports the following heterogeneous scenarios for transactional and snapshot replication:
-
Publishing data from [!INCLUDEssNoVersion] to non-[!INCLUDEssNoVersion] Subscribers.
-
Publishing data to and from Oracle has the following restrictions:
| Scenario | 2016 or earlier | 2017 or later |
|---|---|---|
| Replication from Oracle | Only support Oracle 10g or earlier | Only support Oracle 10g or earlier |
| Replication to Oracle | All versions prior 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 [!INCLUDEssIS].
Caution
[!INCLUDEssNoteDepFutureAvoid]
You can use [!INCLUDEssNoVersion] to publish data from Oracle with most of the same features and ease-of-use as [!INCLUDEssNoVersion] snapshot and transactional replication. This feature requires Oracle version 10G or earlier. Publishing data from Oracle is ideal for the following scenarios:
| Scenario | Description |
|---|---|
| [!INCLUDEmsCoName] .NET Framework application deployments | Develop with [!INCLUDEmsCoName] Visual Studio and [!INCLUDEssNoVersion] while operating on data replicated from a non-[!INCLUDEssNoVersion] database. |
| Data warehousing staging servers | Keep [!INCLUDEssNoVersion] staging databases synchronized with a non-[!INCLUDEssNoVersion] database. |
| Migration to [!INCLUDEssNoVersion] | Test your application in real time against [!INCLUDEssNoVersion] while replicating the source system's changes. Switch to [!INCLUDEssNoVersion] when satisfied with the migration. |
For more information, see Oracle Publishing Overview.
The following non- [!INCLUDEssNoVersion] 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.
