Oracle Service Bus, how to verify Result Caching is active

Oracle Service Bus has a feature now for a while which gives us the option to switch on Result Caching on services. Result Caching is based on Oracle Coherence, an in-memory data grid.

I would rather have some sort of short overview in the...
