Advanced Queuing - Oracle

Working with Messaging Gateway
The native name of the non-Oracle queue (its name in the non-Oracle
messaging system)
Whether it is a queue (point-to-point) or topic (publish-subscribe)
A set of options specific to the non-Oracle messaging system. These options are
a set of {name, value} pairs, both of which are strings.
For MQSeries the only option is ‘MQ_openOptions’. This property corresponds
to the openOptions argument of the MQSeries Base Java
MQQueueManager.accessQueue method. If not specified, the value of
openOptions defaults to MQC.MQOO_OUTPUT on enqueue and MQC.MQOO_
INPUT_SHARED on dequeue.
-- Registering non-Oracle queue
-declare
v_options sys.mgw_properties;
begin
-- No options set for this foreign queue. Below is a sample of how one would
be set.
-- v_options := sys.mgw_properties(sys.mgw_property(‘MQ_openOptions’,
‘2066’));
-- Register the queue
dbms_mgwadm.register_foreign_queue(
name => 'destq', -- MGW non-Oracle queue name
linkname => 'mqlink', -- name of link to use
provider_queue => 'my_mq_queue', -- name of MQSeries queue
domain => dbms_mgwadm.DOMAIN_QUEUE, -- single consumer queue
options => v_options);
end;
The domain parameter is set to DBMS_MGWADM.DOMAIN_QUEUE for point-to-point
queues and DBMS_MGWADM.DOMAIN_TOPIC for publish-subscribe queues. Only
point-to-point queues are supported for MQSeries.
Altering a Registered Queue
After a non-Oracle queue is configured and registered, it cannot be altered. The
registration information must be deleted and re-created.
Unregistering a Non-Oracle Queue
A non-Oracle queue can be unregistered only if there are no subscribers or
schedules referencing it.
