Continuous Queue
JMS Queue Configuration 171
For example, when you set the batch size property to -1 (unlimited), and the
redelivery delay property to 30 seconds (30,000 milliseconds), new messages can
be processed in the queue. Processing continues even when a large number of
errors are being reprocessed.
The same connection factory is used for both the sequential and continuous
queues. To avoid sequential consumer processing issues, set the redelivery delay
value in the destination queue configuration. Do not set the connection factory
level configuration.
If the number of times that a message in error is processed exceeds the configured
try count, the message stops processing and is redirected for error management.
As an alternative to setting the batch size property to -1, you can implement an
error queue. To implement an error queue, you must uncomment entries for the
error queue in the ejb-jar.xml and weblogic-ejb-jar.xml files.
