JMS - retry logic

Question

Currently we have individual Queues for each destination. We are planning to have a single queue. Eventhough we can handle different destination in the message header, how to customise the rety logic.
I mean, say I have three destination A,B &C. When the first message message is targetted to A and suppose its down, how long will the queue keep on retying the same destination? Will it not send subsequent messages to other destinations? Can we customize the retry logic to try for some time and move to next message & destination?

Hi,
Adding the properties as you have them is correct.
When I did this I also had to make a custom fault policy in the DeQueue composite which would not catch the errors.
This meant that the fault caused the message to rollback to the queue.
Fault Bindings.xml:
<?xml version="1.0" encoding="UTF-8"?>
<faultPolicyBindings version="3.0"
xmlns="http://schemas.oracle.com/bpel/faultpolicy"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<!-- Imperial Fault Policy for Reliable ASync Design Patterns -->
          <!-- Domain level Default Policy -->
          <composite faultPolicy="IMPDefaultPolicy"/>
</faultPolicyBindings>
Fault-policies.xml:
<?xml version="1.0" encoding="UTF-8"?>
<faultPolicies xmlns="http://schemas.oracle.com/bpel/faultpolicy" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<faultPolicy version="3.0" id="IMPDefaultPolicy"
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"

<!-- Imperial Fault Policy for Reliable ASync Design Patterns -->
          <!-- We simply want faults to be re-thrown so that the messages rollback to the queues/topics where they came from -->
