IBM Shuffles IBM i CDC Function and Data Replication Tool
March 9, 2016 Alex Woodie
If your IBM i shop uses change data capture (CDC) software from IBM, you’ll be interested to know that last week IBM announced that it’s no longer selling the InfoSphere Change Data Capture for DB2 on IBM i as a separate product. It made the change because that same IBM i-based CDC engine can now be found in the latest release of its InfoSphere Data Replication product.
InfoSphere Change Data Capture traces its lineage directly to DataMirror’s Transformation Server, the journal-based data replication tool at the center of IBM’s acquisition of DataMirror in July 2007. Nearly a year later, IBM re-released delivered InfoSphere Change Data Capture version 6.2 which marked the name change from Transformation Server.
Big Blue laid out the changes in IBM United States Software Announcement 216-062. Essentially, the company is moving its core IBM i-based CDC engine that’s been at the heart of the InfoSphere Change Data Capture V6.1 for DB2 on IBM i product to the InfoSphere Data Replication product.
“The InfoSphere Data Replication product previously included the Change Data Capture V6.1 and V6.2 software as supporting programs to provide access to the iSeries engine,” IBM says. “Beginning with InfoSphere Data Replication V11.3.3, the iSeries engine is now a part of the InfoSphere Data Replication product. Clients no longer need to use the Change Data Capture version of the software because the same function is available to clients using the InfoSphere Data Replication V11.3.3 iSeries engine.”
The InfoSphere Data Replication software supports three forms of data replication, including CDC, SQL replication, and Q replication. Since the CDC engine in this product is the same product that IBM sold separately as InfoSphere Change Data Capture V6.1 for DB2 on IBM i, the company decided to simplify its product lineup.
InfoSphere CDC customers who become InfoSphere Data Replication customers, will gain a little bit more functionality. That’s because, while Q replication (which uses WebSphere MQ) doesn’t work on IBM i, the DB2 for i database can support SQL replication (although it does require the customer to purchase DB2 Information Integrator if they want to replicate data to or from a non-DB2 data source).
IBM will stop selling InfoSphere Change Data Capture V6.1 for DB2 on IBM i on September 30. For more information on how to upgrade the IBM i CDC engine from version 6.1 to version 11.3.3, see www.ibm.com/support/knowledgecenter/SSTRGZ_11.3.3/com.ibm.cdcdoc.cdcfori.doc/tasks/upgrading.dita.
