Sequential Queues
JMS Queue Configuration
165
3
Configure your external system and enterprise services to use the queues.
4
To enable message processing, you must configure the consumers value of the
message queue.
The system processes the messages after they are written to the queue.
Sequential Queues
The sequential queue is a JMS queue with a system cron task as a consumer.
Messages in sequential queues are processed on a strict first-in-first-out basis,
ensuring that messages are processed in the order that they are generated and
received. When a message results in an error, the system generates an error file
and does not process subsequent messages in the queue until the error is cleared.
You can configure two system sequential queues for inbound and outbound
message processing. A predefined cron task, JMSQSEQCONSUMER, polls the
queues. There are two instances of the task, one that polls the inbound queue and
one that polls the outbound queue.
The following table describes the cron task parameters that you can configure.
Continuous Queue
The continuous queue is a JMS queue with a message-driven bean (MDB) as a
consumer.
By default, this queue is configured for enterprise services only. The queue does
not process messages in first-in-first-out sequence, as the sequential inbound
queue does. Messages are processed in a multi-threaded mode, which produces
better system performance.
Parameter
Description
MESSAGEPROCESSOR
Java class that processes the messages from the
queue. The system provides this class.
QUEUENAME
Queue JNDI name, when the queue is created on
the application server.
SELECTOR
The WHERE clause for configuring an instance of
the cron task to process a subset of messages in
the queue. This parameter is optional.
TARGETENABLED
The Boolean flag that controls whether the cron
task runs in a specific application server. The
default is 0 (false).
This parameter applies only when the system is
running a multi-application server environment.
