My current customer has a SOA Suite implementation dating from the 10g era. They use many queues (JMS serves by AQ) to decouple services, which is in essence a good idea.
However, there are quite a load of them. Many composites have several adapter specifications that use the same queue, but with different message selectors. But also over composites queues are shared.
There are a few composites with ship loads of .jca files. You would like to replace those with a generic adapter specification, but you might risk eating messages from other composites. This screendump is an anonymised of one of those, that actually still does not show every adapter. They're all jms adapter specs actually. Read the complete article here.
