Infosphere Data Replication for IMS

The core architecture comprises three main components: the Replication Engine, Capture, and Apply components. The Replication Engine acts as the central control point, managing the replication process, including scheduling, error handling, and overall coordination. The Capture component is responsible for extracting data changes from the source IMS databases.

It utilizes IMS logging to identify and capture changes. The Apply component applies the captured changes to the target IMS databases. Communication between these components occurs primarily through z/OS internal mechanisms and TCP/IP for network communication.

The product uses IMS databases for both source and target data storage. The Replication Engine uses configuration files to define replication rules, data mappings, and performance settings. The Capture component interacts with IMS logs, and the Apply component uses IMS APIs to apply changes.

Ports required for communication include those used by TCP/IP. The product supports RACF for authentication, ensuring secure access. The product's design is optimized for high-volume IMS environments, providing efficient data replication.

The product's architecture is specifically tailored to the IMS environment, offering optimized performance and integration.
