I want to set no of threads (and also if possible something like polling frequency) to increase no of messages picked up per time frame for OSB AQ Adapter (JCA proxy service).
How can I do that?
For SCA composites, there is an option of adding 'adapter.aq.dequeue.threads' property in composite.xml
Surprisingly, there is no similar option available for OSB. No properties like NumberOfThreads for DB JCA are allowed in AQ JCA file (i.e. for className="oracle.tip.adapter.aq.inbound.AQDequeueActivationSpec").
You could change the max-threads-constraint, min-threads-constraint properties to control the number of threads that are allocated to your proxy service. Configure an appropriated values based on your requirement and infrastructure.
