Product Overview

The architecture of Message Driven Processor comprised several key components. The message queue manager was responsible for storing and retrieving messages, providing a persistent and reliable message store. The message processing engine handled message routing, transformation, and delivery.

Adapters were used to interface with CICS applications, enabling the exchange of messages between client applications and CICS transactions. Configuration was managed through JCL and control statements, which defined message queues, routing rules, and other operational parameters. The system used proprietary protocols for communication.

The main workflow involved client applications sending messages to the message queue manager, which then routed the messages to the appropriate CICS applications via the processing engine and adapters. Due to the product's end-of-life status, organizations should migrate to modern messaging platforms like IBM MQ. This migration involves re-architecting applications to use the new middleware's APIs and protocols.

The transition requires careful planning to ensure minimal disruption to existing systems and data integrity. The new architecture should include components for message queuing, routing, and transformation, along with adapters for CICS integration.
