BMC AMI Message Advisor for IMS

The architecture of BMC AMI Message Advisor for IMS is centered around several key components that work together to provide comprehensive message management capabilities. The primary components include the ISPF interface, the Message Monitor, the Message Capture Engine, the Message Replay Engine, and the VSAM data storage. The ISPF interface serves as the primary user interface, providing access to all product features.

The Message Monitor continuously monitors message queues, checking for errors based on predefined thresholds. The Message Capture Engine intercepts and stores production messages, while the Message Replay Engine replays these messages in a development environment. Communication between components occurs primarily through z/OS system services and IMS APIs.

The product utilizes VSAM datasets for storing configuration data, monitoring results, and captured messages. The ISPF interface interacts with the other components via internal APIs and system calls. The Message Monitor and Capture Engine communicate with IMS regions using standard IMS interfaces.

The Message Replay Engine interacts with IMS test regions to replay captured messages. Network requirements are minimal, primarily involving connectivity to the IMS regions being monitored and tested. The product's design emphasizes efficient message processing and minimal impact on IMS performance.
