A system for routing an application message detects that routing rules are dynamic and static. The system then invokes a rules engine to receive the dynamic routing rules and interleaves the dynamic routing rules with static routing rules. The system then executes the interleaved rules to route the message.

Mediator with interleaved static and dynamic routing

Described is an improved method, system, and computer program product for implementing an improved resequencer, along with related mechanisms and processes. Some embodiments provide an approach for generating a message sequence having start and increment values.

Method and system for implementing sequence start and increment values for a resequencer

Described is an improved method, system, and computer program product for preventing concurrent access and processing of data by multiple threads. The inventive approach may be applied to prevent concurrent access in resequencers.

Method and system for implementing a scalable, high-performance, fault-tolerant locking mechanism in a multi-process environment

Described is an improved method, system, and computer program product for implementing an improved resequencer, along with related mechanisms and processes. An improved error handling method and system for messages is also described.

Method and system for performing blocking of messages on errors in message stream

Embodiments of the present invention enable processing of tasks within a service-oriented architecture (SOA). In embodiments, an echo mediator is a mediator SOA component that acts as a service provider by processing a service request associated with a service requester and returning the result to the service requester. In embodiments, an echo mediator handles a received sequential service request by synchronously processing it. In embodiments, an echo mediator handles a received parallel service request by storing it in a persistent store, and an echo mediator with processing capacity retrieves the stored parallel service request and asynchronously processes it. In embodiments, a group of echo mediators may be distributed among the nodes of a grid, forming an echo mediator grid in which each of the echo mediators interfaces with a common data store deployed within the grid. In embodiments, the grid of echo mediators balances the processing of stored service requests.

Processing of service-oriented tasks within a grid computing environment

Additional synonym pairs are inferred from a pair of schema elements (of different schemas) mapped by a user, and the inferred pairs are added to a dictionary. According to one aspect of the present invention, a mapped pair is inferred as a synonym pair if the elements of the mapped pair cannot be mapped according to a program logic otherwise. According to one more aspect of the present invention, the parents of the mapped elements are also inferred as synonym pairs if sufficient peer (to the mapped elements) elements are already mapped or considered synonyms.
