Licensing Tips for IBM Data Replication .
No, not if you have InfoSphere Data Replication or InfoSphere Replication Server on UNIX or Windows. On those operating systems, Data Replication and Replication Server contain a complete set of IBM's data federation technology for use in data replication solutions*. For example, you can replicate to a PostgreSQL or an Oracle database using the Federation Server technology found in the Replication Server install. If you have any other data replication product, you may be able to use a copy of Federation Server to go to target databases not supported by that replication product. You'd need to work with an expert for that product to know for sure. Note also that, if you have Federation Server, the Federation Server license does not allow general use of the replication components found in Federation Server. That replication technology can only be used in support of building a database cache using cache tables.
* Data Replication and Replication Server solutions for mainframe data sources such as IMS and VSAM (called 'Classic' data sources) require a 'Classic' data replication product instead of data federation. Therefore, the mainframe federation technology for Classic data (Classic Federation Server) is not included in the purchase of Data Replication or Replication Server on UNIX or Windows.
