I've been surprised recently by the number of people who still have an old IBM product called DataPropagator, or 'DProp'. More suprising is that they think they're at a dead end with no replacement. Nothing could be further from the truth. DataPropagator was a product name. Product names, as I'll show later, can change. However, the underlying technology remains. In DataPropagator's case, the technology inside it is what IBM calls SQL Replication. SQL Replication is alive and well. You can find it in several IBM products.
For example, if you're on z/OS and currently running DB2 DataPropagator or DataPropagator Relational, the DProp function can now be found in the SQL Replication feature of WebSphere Replication Server v9.1 and InfoSphere Replication Server v10 as well as IBM's newer InfoSphere Data Replication product. This is important information because, if you move to DB2 z/OS v9 or v10, you must upgrade to one of these newer replication products because they contain the only level of DProp function that supports the newer DB2s.
Getting back to the subject of name changes, here is a graphic that shows the transformation of 'DProp' names on z/OS.
What If You're Current on S&S?
You may want to know what you're entitled to if you had purchased DataPropagator and are current on S&S. The easy thing to do is to search IBM announcement letters for 'datapropagator'... okay :) maybe it's easier said than done, so here's the ones that answer the question:
In a nutshell, they say that DataPropagator (v7 and v8) have been replaced by WebSphere Replication Server. v9. Of course, in 2010, v10 of Replication Server was released and its brand was changed to InfoSphere. Customers can move to Replication Server v10 if they are current on DataPropagator S&S.
The following lists add some comments about what else changed for each of these name changes:
- 1990: IBM Data Propagator
- The first - this product only replicated data between IMS and DB2.
- This product replicated between DB2 databases.
- A companion product, DataPropagator NonRelational, replicated data from IMS to DB2.
- A little later, IBM's data federation product, DataJoiner, provided the basis for heterogeneous SQL Replication between DB2 and other relational databases.
- 2000: DB2 DataPropagator
- This was the start of a new, improved implementation of SQL Replication.
- The NonRelational product was renamed to IMS DataPropagator.
- A new data replication technology, Q Replication, was added as a high-performance alternative to SQL Replication.
- On UNIX and Windows, this merged data replication and federation into a single product.
- A new release and a brand change - from DB2 to WebSphere.
- The end of Information Integrator.
- All data replication needs are now contained in a single product with a replication name.
- A new version and a brand change - from WebSphere to InfoSphere.
- A merging of InfoSphere Replication Server and InfoSphere CDC.
If anyone knows of anything I missed, feel free to add it to the comments :)
