Abstract

Generating exception delay messages when messages communicated between asynchronous messaging applications are delayed and for forcibly retaining the original message. Specifically, the invention provides methods and systems for generating an exception delay message after a time threshold has expired without deleting the original message. The exception delay message may be sent once when the time threshold first expires or each time that the time threshold expires.

Claims

1. A method for generating a second message, comprising the steps of:

putting a first message comprising a time threshold data item;

determining whether the time threshold data item has expired;

generating, in response to the determination that the time threshold data item has expired, the second message, wherein the second message indicates that the time threshold data item has expired; and

forcibly retaining the first message.

2. The method of claim 1, wherein the time threshold data item comprises a time interval and the second message is generated each time that the time interval expires.

3. The method claim 2, wherein the amount of time before the threshold expires is passed within the first message when the first message in transferred from a first message queue manager to a second message queue manager.

4. A system for generating a second message, the system comprising:

a first message comprising a time threshold data item;

a plurality of message queues for storing messages;

a plurality of message queue managers for transmitting, receiving and storing messages in the plurality of message queues and determining whether a time threshold data item of a message has expired, wherein each message queue manager is operable to;

transmit a first message, comprising a time threshold data item;

determine whether the time threshold data item has expired;

generate, in response to the determination that the time threshold data item has expired, the second message, wherein the second message indicates that the time threshold data item has expired; and

forcibly retain the first message.

5. The system of claim 4, wherein the time threshold data item comprises a time interval and each message queue manager is operable to generate a second message each time that the time interval expires.

6. The system of claim 4, wherein the first message comprises an amount of time before the threshold data item expires as of when the first message is transferred from one node to another node.
