Integration

Hi all.

I'm starting to work with JMS adapter and need some help to understand it's message handling behaviour.

Im my test scenario, I have a TIBCO JMS Queue where I have to consume its messages using Oracle ESB JMS Adapter.

Question 1: If at a given point in time the Queue has 100 messages, how the JMS Adapter handle them, one by one, or is it possible to configure threads and consume all messages at the same time?

Question 2: Given the Question 1, how would this work if we had a Topic instead of the Queue?

Question 3: When the JMS Adapter consumes messages from a Queue, how does it know about a new message? Does it register to the Queue and the Queue singns the Adapter of a new Message? Does it polls for new messages from time to time?

Question 4: I have configured JMS Adapter to consume messagens from a TIBCO Queue using ESB I made this configuration in two SOA Suite environments. In one of the environments, when I deploy the ESB project, it does not consume the messages from the Queue (it does not work at all). I've looked for message logs in OPMN log files, OC4J log files, etc, and didn't find anything suspect.

How can I know, by consulting logs or anything else, if the steps below were acomplished or not?

a) the class com.tibco.tibjms.naming.TibjmsInitialContextFactory was successfully found and loaded.

b) the Adapter is acctually listening to the Queue. The console shows that the ESB flow is up and running, but, how do you know if it is acctually working?

Maybe those are newbie questions, but I don't know how to answer them :-P

Thanks
