Solution Overview

Problem

Existing systems face challenges in interfacing applications with distributed transaction coordinators across different runtime environments, particularly due to incompatibilities between .NET and COM environments, which hinder effective participation in distributed transactions.

Innovation Solution

The system and method involve generating new mechanisms such as queues, threads, enlistment objects, semaphores, and locks to facilitate communication and data exchange between .NET and COM runtime environments, enabling client applications to participate in distributed transactions managed by a distributed transaction coordinator operating in a different environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If applications operate in .NET runtime environment and distributed transaction coordinator operates in COM runtime environment, then each environment can optimize its own transaction handling, but compatibility issues prevent effective communication and transaction coordination between the two environments

Engineering Contradiction:
Improvetransaction coordination reliabilityVSAvoidruntime environment compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements an interface layer that acts as an intermediary between .NET and COM runtime environments. This interface receives distributed transaction requests from applications in one environment, translates them into the appropriate format for the other environment, and coordinates the transaction flow. The interface includes components for message serialization, protocol translation, and transaction state synchronization, enabling reliable transaction coordination across incompatible runtime boundaries without requiring direct compatibility between .NET and COM environments.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If direct interfacing between .NET and COM environments is attempted, then integration can be achieved, but system complexity increases due to the need for multiple translation and adaptation layers

Engineering Contradiction:
Improvecross-environment integrationVSAvoidinterface implementation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal interface architecture that handles multiple functions within a single coordinated system. The interface layer provides multi-functional capabilities including transaction request routing, protocol translation, message serialization/deserialization, error handling, and transaction state management. By consolidating these diverse functions into a unified interface framework, the system achieves cross-environment integration without requiring separate complex translation layers for each function, thereby reducing overall system complexity while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If transaction requests are translated between different runtime environments, then compatibility is achieved, but transaction processing time increases due to additional translation and coordination overhead

Engineering Contradiction:
Improveenvironment compatibilityVSAvoidtransaction processing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action mechanisms including pre-serialization of transaction messages, pre-validation of transaction requests, and pre-establishment of communication channels between .NET and COM environments. Transaction protocols and message formats are standardized in advance, allowing the interface layer to process requests efficiently without performing complex translations during actual transaction execution. Connection pooling and cached translation tables further reduce processing time by preparing translation resources beforehand, minimizing the time penalty associated with cross-environment transaction coordination.

Inventive Principle:
Principle #10Preliminary action

AI summary

In certain embodiments, a method for interfacing an application to a distributed transaction coordinator includes receiving a distributed transaction request from an application in a first runtime environment. In response to the request, the application is enlisted with a distributed transaction coordinator in a second runtime environment. The first runtime environment is at least partially distinct from the second runtime environment. A transaction identifier is received from the distributed transaction coordinator. A first resource manager is invoked to enlist in the distributed transaction using the transaction identifier and a second resource manager is invoked to enlist in the distributed transaction using the transaction identifier.
