I am working on a multithreaded JMS receiver and publisher code (stand alone multithreaded
java application). MOM is MQSonic.
XML message is received from a Queue, stored procedures(takes 70 sec to execute) are called and response is send to Topic within 90 sec.
I need to handle a condition when broker is down or application is on scheduled shutdown. i.e. a condition in which messages are received from Queue and are being processed in java, in the mean time both Queue and Topic will be down. Then to handle those messages which are not on queue and not send to topic but are in java memory, I have following options:
(1) To create CLIENT_ACKNOWLEDGE session as :
connection.createSession(false, javax.jms.Session.CLIENT_ACKNOWLEDGE)
Here I will acknowledge message only after the successful completion of transactions(stored procedures)
(2) To use transacted session i.e., connection.createSession(true, -1). In this approach because of some exception in transaction (stored procedure) the message is rolled back and Redelivered. They are rolled back again and again and continue until I kill the program. Can I limit the number of redelivery of jms messages from queue?
Also in above two approached which one is better?
