Service Manager for SOA Transaction and Debugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing business software applications face challenges in providing flexible and consistent service management across different components, particularly in ensuring data consistency, concurrency, and debugging within a service-oriented architecture.
Innovation Solution
A method and system that utilize a service manager to collect requests, execute methods based on semantic descriptions from a repository, add tracing functionality, and manage transactions, allowing for flexible construction of services across application server components with consistent functionalities like transaction and concurrency management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service-oriented architecture is implemented with multiple application components, then service flexibility and reusability are improved, but ensuring data consistency and managing transactions across components becomes more complex
Solution Approach 1:
The patent introduces a service manager as an intermediary component that coordinates transactions across multiple application components. The service manager receives service requests, identifies the involved components, and manages the transaction lifecycle including setting transaction attributes, committing transactions, and handling rollbacks. This mediator approach resolves the contradiction by centralizing transaction management while preserving component flexibility.
Solution Approach 2:
The service manager is designed as a universal component that handles multiple functions: service request routing, transaction management, concurrency control, and debugging coordination. By consolidating these diverse functions into a single multi-functional component, the system achieves transaction consistency across flexible service-oriented architecture without proportionally increasing complexity.
2Difficulty of detecting and measuring
If tracing functionality is added to monitor method execution across components, then debugging capability is improved, but system complexity and overhead increase
Solution Approach 1:
The service manager acts as an intermediary that collects and coordinates tracing information from multiple application components during method execution. Rather than each component implementing its own complex tracing system, the service manager centralizes the collection and management of tracing data, improving debugging capability while avoiding the complexity of distributed tracing implementation across all components.
3Reliability
If semantic descriptions are checked against service requests, then service consistency and correctness are improved, but request processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-compiling service requests and pre-fetching semantic descriptions before actual service execution. The service manager prepares the matching criteria and available service information in advance, so that when a service request arrives, the semantic matching can be performed more efficiently. This reduces the time penalty of consistency checking while maintaining service correctness.
