FAULT TOLERANT RETRY SUBSYSTEM AND METHOD

摘要

A fault-tolerant retry subsystem, method and computer program product are provided in order to automatically retry to deliver a message. In the context of a fault-tolerant retry subsystem, processing circuitry is provided to receive notification that delivery of a message to a subscriber has failed. The processing circuitry also defines a time interval at which delivery of the message is to be retried. The message is to be subjected to a plurality of retry attempts in an instance in which the delivery of the message to the subscriber continues to fail. The time interval is defined in a manner that depends upon which of the plurality of retry attempts is to be performed. As such, the time interval varies between at least some of the retry attempts. The processing circuitry causes the delivery of the message to be retried following expiration the time interval.

主权项

1. A fault-tolerant retry subsystem for automatically retrying to deliver a message, the fault-tolerant retry subsystem comprising a processing circuitry configured to:
receive notification that delivery of the message to a subscriber has failed; define a time interval at which delivery of the message is to be retried, wherein the message is to be subjected to a plurality of retry attempts in an instance in which the delivery of the message to the subscriber continues to fail, and wherein the time interval is defined in a manner that is dependent upon which of the plurality of retry attempts is to be performed such that the time interval varies between at least some of the retry attempts; and cause the delivery of the message to be retried following expiration of the time interval.
