This article is to give some ground reality of the challenges in resolving some of the customer reported issues with complex and powerful replication engines like InfoSphere CDC. These time consuming challenges are apart from the development complexities. Background : InfoSphere CDC is an application on top of a database. It captures the changes happening in the database via DDL or DML statements via logical logs and appropriately apply on the target database. This model does not intrude the source database as CDC simply reads the logs as it appear. This capability is needed by many customers as their source database will be in production and the production system must not be hindered by any extra load. Platforms : InfoSphere CDC is supported on almost all the major platforms, on all the major operating systems and on almost all the major databases. So, a simple problem reported by customer could require a specific environment to be set by the engineering for reproducing the pro...
