Automated delayed message redelivery
First Claim
1. A computer implemented method for delivering an event message in an asynchronous communication system, the method comprising:
- generating the event message at a publisher and publishing the event message from the publisher to at least one subscriber;
advancing a micro retry counter in a subscriber adapter when the at least one subscriber is unable to process the event message;
determining, with the subscriber adapter, whether the micro retry counter has exceeded N micro retries, wherein the subscriber adapter verifies the event message conforms to a business logic of the at least one subscriber before the micro retry counter reaches N number of micro retries; and
forwarding the event message to a redelivery manager once the micro retry counter reaches N number of micro retries.

Abstract
Method and system are disclosed for redelivering failed messages in asynchronous communication systems. The methods and systems automatically delay redelivery of such failed messages in order to allow required system resources to become available. In one implementation, the methods and systems provide two levels of redelivery: a micro level in which redelivery is attempted right away for a certain number of times, and a macro level in which a predefined, user-selectable delay is imposed before any additional micro level redeliveries are attempted. After a certain number of unsuccessful macro level redeliveries, the message is backed out to a backout queue for manual intervention by a system operator. Such an arrangement reduces or eliminates the burden on the system operator to manually resolve failed message deliveries.

8. A non-transitory computer-readable medium having computer-executable instructions stored thereon that are executed by a processor to:
-
send an event message at a publisher and publish the event message from the publisher to at least one subscriber; advance a micro retry counter in a subscriber adapter when the at least one subscriber is unable to process the event message; determine, with the subscriber adapter, whether the micro retry counter has exceeded N micro retries, wherein the subscriber adapter verifies the event message conforms to a business logic of the at least one subscriber before the micro retry counter reaches N number of micro retries; forward the event message to a redelivery manager once the micro retry counter reaches N number of micro retries; and advance a macro retry counter, with the redelivery manager, upon receiving the event message and wait a user-selectable amount of time before republishing the event message to the at least one subscriber for an additional N number of micro retries. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A system for delivering an event message in an asynchronous communication system, the system comprising:
-
at least one subsystem configured to format the event message at a publisher and publish the event message from the publisher to at least one subscriber, wherein a section of the event message is designated, at the publisher, for storing message redelivery information based on the format of the event message; at least one subsystem configured to advance a micro retry counter in a subscriber adapter when the at least one subscriber is unable to process the event message; at least one subsystem that determines, with the subscriber adapter, whether the micro retry counter has exceeded N micro retries, wherein the subscriber adapter verifies the event message conforms to a business logic of the at least one subscriber before the micro retry counter reaches N number of micro retries; and at least one subsystem that forwards the event message to a redelivery manager once the micro retry counter reaches N number of micro retries. - View Dependent Claims (17, 18, 19, 20)
