Session Manager Centralizes Multithreaded Task Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In business management systems, privileged users lack centralized control over multiple sub-tasks, leading to resource leaks and inefficient monitoring of sessions, especially in multithreaded server applications where tasks can go out of control, causing memory and computing cycle leaks.
Innovation Solution
A Session Manager is introduced to register, monitor, and maintain execution tasks, providing a central repository for all running sessions, allowing for better control over task execution, resource management, and handling of stalled or waiting tasks by assigning new clients and listeners to unblock background processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If privileged users directly manage multiple sub-tasks in multithreaded server applications, then task execution flexibility is improved, but resource leaks and system instability occur due to lack of centralized control
Solution Approach 1:
A Session Manager component is introduced as an intermediary between privileged users and multiple sub-tasks. The Session Manager maintains a centralized registry of active sessions, tracks their states, and coordinates task execution. This mediator approach allows flexible task management while preventing resource leaks through centralized monitoring and controlled access to session information.
2Difficulty of detecting and measuring
If users can access and monitor all active sessions, then monitoring capability is improved, but information security is compromised as sensitive business data may be exposed
Solution Approach 1:
The Session Manager implements local quality by providing different levels of session information access to different users or components. Instead of exposing all session details universally, it selectively reveals only necessary information (such as session state, progress, or specific metrics) while keeping sensitive business data protected. This selective information disclosure maintains monitoring capability without compromising security.
3Loss of energy
If a centralized Session Manager is introduced to control all sessions, then resource management is improved, but system complexity increases
Solution Approach 1:
The Session Manager is designed as a universal component that performs multiple functions: registering sessions, tracking their states, monitoring progress, coordinating task execution, and preventing resource leaks. By consolidating these diverse functions into a single multi-functional component, the system reduces overall complexity compared to having separate mechanisms for each function, while still achieving comprehensive resource management.

AI summary
According to one general aspect, a method may include acquiring, by a session manager, a list of active sessions. In various embodiments, each session may include a grouped plurality of sub-tasks that are configured to be sequentially performed in order to accomplish a business management task. In some embodiments, the method may include receiving a selection of one of the sessions to supervise. In one embodiment, the method may include retrieving a list of the at least one event listener(s) from a session context associated with the selected session. In another embodiment, the method may include receiving events generated by the session.
