Hi Robert,
 I guess it depends :-). Depending on your needs, you can either use
competing consumers over point to point queues, or
pub/sub broadcasting. If you are in a j2ee 1.3 environment, you can easily
set up MDB's to consume the event messages.
Otherwise, you will have to bootstrap the consumers on your own (Service
Activators either in a startup servlet or as a custom
service, etc.).

The easiest is probably using point to point queues to process the events,
then you will only consume the event once, depending
also on your needs for message expiration, etc. Which appserver and
available jms providers are you using?

Jin,
How does that work when I have a clustered j2ee server?
How would AQ comunicate with cluster? Would I need an load balancer between
the two?
Thanks.
robert

Hi Robert,
  not off hand :-), but there should be plenty of examples/docs off of
the oracle otn site.
We aren't doing that specific thing where I am currently, but we have had
multiple jms providers integrated
into the same application server. Following the terminology from the
enterprise integration patterns site
(which is really good IMHO), you can either send the event using push (the
data with the event) or pull
(just the notification, and grab the data yourself).

Jin,
Yes I think that this will work, this is what I was thinking of doing :)
Do you have any links of actual implementations of this?
Thanks.

JMHO, but you could always put a trigger on the table, and have the trigger
send
a notification event message off to oracle aq, then have your appserver
code binding
to aq through their jms apis, take the notification as an event message and
do the rest
of the processing.

Hi,
Is there a pattern standard way of accomplishing that?
I am looking to notify j2ee server that insert or update happened on a
perticular table in Oracle.
Thanks for your input.
robert
