Abstract
Provided is a method for duplicate message elimination A plurality of message threads process operations to deliver messages from a message store to a destination queue. An in-doubt list is generated identifying messages that are in-progress of being delivered from the message store to the destination queue by the message threads. One message thread processing one message adds an entry including the message identifier to a monitor queue. The message thread further adds the message to the destination queue. A recovery thread is generated in response to detecting a failure in the processing by the threads to deliver the messages from the message store to the destination queue. The recovery thread processes the messages indicated in the in-doubt list and compares with message identifiers in the monitor queue to prevent duplicate delivery of messages to the destination queue.
