Continuous queues
A continuous queue is a JMS queue with a message-driven bean (MDB) as a consumer. A continuous queue is predefined for enterprise services only and uses multi-threaded processing to provide better system performance. A continuous queue does not guarantee the processing order of the messages as is the case with a sequential queue.
When message processing results in an error that can be managed in the message reprocessing application, the system generates an error message and then continues processing subsequent messages in the queue. There is one default continuous queue to process inbound messages. You can choose to implement additional continuous queues, depending on your integration requirements.
