Message queue configuration
The external system defined for the cron task that imports software catalogs uses the default Control Desk queue names and continuous queues.
| Queue name | Java™ Naming and Directory Interface (JNDI) name |
|---|---|
| Sequential queue in | jms/maximo/int/queues/sqin |
| Sequential queue out | jms/maximo/int/queues/sqout |
| Continuous queue in | jms/maximo/int/queues/cqin |
| Continuous error queue | jms/maximo/int/queues/cqerr |
Configuration of the queues is performed using the console provided by the application server. For detailed information about configuring the queues, see the documentation provided with your application server. If you use WebSphere® Application Server, the installer ensures that these queues are defined. If you use Oracle WebLogic Server, you must manually configure these queues.
The following parameters
are important in queue configuration; you can access them using the
application server console.
- Reprocessing Delay: A delay of at least several seconds is desirable so that dependencies are committed to the database before reprocessing occurs.
- Reprocessing Timeout: The timeout must allow for reprocessing due to dependencies, but eliminate records once the likelihood of a dependency being loaded passes (usually several seconds).
- Error Destination – Errors can be placed in files on the operating system, discarded, or placed in error queues. If using the continuous queue, messages should not be immediately discarded because some reprocessing is required by design.
