摘要:
A client computer group is created at a server computer by selecting a subset of a group of client computers, where each of the group of client computers has a separate communication channel with the server computer. A message from at least one of the subset of the group of client computers is received at the server computer. In response to receiving messages from at least two of the subset of the group of client computers within the client computer group, the messages are grouped under a single unit of work. A single decision associated with the single unit of work for the client computer group is computed. Each of the at least two of the subset of the group of client computers is operable to accept the single decision.

Embodiments of the present invention provide a method, system and computer program product for configurable pacing in messaging systems. In an embodiment of the invention, a configurable message pacing method has been provided. The method includes receiving a message directed for placement in a repository of an intermediate messaging system into which messages are placed by message producing applications and from which messages are retrieved by message consuming applications. Thereafter, it can be determined if the placement of the received message into the repository will result in a breach of an associated threshold value for the repository. Consequently, a message pacing action can be triggered responsive to the determination that the placement of the received message into the repository will result in a breach of the associated threshold value for the repository.

A method, system, and computer program for delivering messages and data to competing consumers. One aspect of the invention includes a message delivery system including a destination messaging engine, one or more receiver messaging engines, and a message pool. The destination messaging engine is configured to distribute data from one or more producers. The receiver messaging engines are configured to request data from the destination messaging engine and transmit the data to one or more consumers. The message pool is configured to store data from the producers, with the destination messaging engine arbitrating data in the message pool among the receiver messaging engines.

In response to publication of a topic message on a topic to a messaging system by a publisher application, a determination is made as to whether any subscriber applications are registered for the topic. In response to determining that at least one subscriber application is registered for the topic, the published topic message is delivered to each registered subscriber application. In response to determining that no subscriber applications are registered for the topic, the published topic message is stored and in response to receipt of a first subsequent subscription request from a new subscriber application for the topic, the stored published topic message is delivered to the new subscriber application.

There is disclosed a source messaging system having a queue for receiving messages. The source messaging system has means for determining whether a message should be permitted to become INDOUBT. This is done by retrieving a value denoting the maximum number of messages that may be permitted to become INDOUBT at any one time; determining whether the message falls within the range denoted by the value; and responsive to determining that the message falls within the range, permitting the message to become INDOUBT.
