SQOUT (Sequential) JMS Queue behaving continuosly

Troubleshooting


Problem

This document describes and proposes solutions for a problem with the Integration Framework JMS Sequential Queue

Symptom

Maximo Integration Framework uses two JMS queue types: Sequential and Continuous Queues.

By default, when TPAE is installed, these queues are defined:

SQOUT - Sequential OutBound Queue
CQIN - Continuous InBound Queue
SQIN - Sequential InBound Queue

The main difference between Sequential and Continuous queues is the error management.

For Continuous Queues ( with exception queue defined ) the messages processing will not stop if an error occurs, instead, the error is moved to the error queue and the next messages are processed and the integration flows with no stops.

For Sequential Queues, the message processing stops whenever an error occurs and the integration flow stops and a manual interaction is required to either solve the problem or delete the error message so the other messages can processed.

In some situations, a Sequential queue may wrongly behave as a Continuous queue and keep processing all messages regardless the errors in the queue. This may cause problems with data integrity in the external system.
