Advanced Queuing - Oracle

Working with Messaging Gateway
Unregistering a Queue: Example
begin
dbms_mwgadm.unregister_foreign_queue(‘destq’, ‘mqlink’);
end;
Monitoring the Status of a Registered Non-Oracle Queue
You can use the MGW_FOREIGN_QUEUES view to check which non-Oracle queues
are registered.
Checking Which Queues Are Registered: Example
SQL> select name, link_name, provider_queue from MGW_FOREIGN_QUEUES;
NAME LINK_NAME PROVIDER_QUEUE
------------------------------------
DESTQ MQLINK my_mq_queue
AQ Queues
You do not need to register AQ queues. When AQ queues are referenced,
Messaging Gateway accesses them directly.
Configuring Propagation Jobs
Propagating messages from one queue to another queue requires a propagation job.
A propagation job consists of a propagation subscriber and a propagation schedule,
hereafter called a subscriber and a schedule. The subscriber specifies the source and
destination queues, while the schedule specifies when the propagation job is
processed. A subscriber without an associated schedule is not processed. For a
schedule to be associated with a subscriber, it must have the same propagation
source and propagation destination.
A Messaging Gateway subscriber does not necessarily correspond to a subscriber in
a non-Oracle messaging system, unless that system has such a notion. Note that a
Messaging Gateway subscriber for an AQ queue is not the same thing as an AQ
subscriber on that queue. However, creating a Messaging Gateway subscriber
results in the creation of a corresponding AQ subscriber.
