Message Queue Manager for Multi-Component Application Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-component applications face disruptions and become nonresponsive when one component halts message processing, affecting others sharing the same queue, leading to system-wide crashes.
Innovation Solution
Implementing a message queue manager that detects unresponsive components, detaches them from the shared queue, manages their messages separately, notifies users, and provides recovery options, while allowing responsive components to continue processing messages and reattaching the component when it becomes responsive again.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a shared input message queue is used for multiple components, then message processing efficiency is improved, but system reliability deteriorates when one component becomes unresponsive
Solution Approach 1:
The patent segments the shared message queue into separate queues for each component. Instead of using a single shared queue where all components compete for messages, each component has its own dedicated queue. This segmentation isolates failures so that when one component becomes unresponsive, only its specific queue is affected, not the entire message processing system. The queue manager independently manages each component's queue, preventing cascade failures.
2Quantity of substance
If components share a common message queue, then resource utilization is improved, but ease of operation deteriorates due to inability to recover individual components
Solution Approach 1:
The patent introduces a queue manager as an intermediary between components and message queues. The queue manager acts as a mediator that monitors component responsiveness and manages queue assignments. When a component becomes unresponsive, the queue manager detects this condition and can redirect messages to alternative queues or components, providing automatic recovery mechanisms without requiring manual intervention. This intermediary layer enables resilient resource utilization while simplifying operational complexity.

AI summary
Various embodiments provide message queue management techniques designed to reduce the likelihood of multi-component applications becoming nonresponsive and enable recovery options for individual components if they do become nonresponsive. In at least some embodiments, a message queue manager detects when a component of an application interface becomes nonresponsive and detaches the component from a shared message queue. The shared message queue can continue to process messages for other responsive components while messaging for the nonresponsive component is managed via a separate queue. The message queue manager can also notify a user regarding the nonresponsive component and provide the user with options to facilitate recovery of the nonresponsive component. Further, in at least some embodiments, the message queue manager can monitor a detached component and reattach the detached component when it becomes responsive again.
