Tuning of Service Engines
Oracle BPEL Process Manager provides several property settings that can be
configured from Oracle Enterprise Manager Fusion Middleware Control to op-
timize performance for response times, throughput, and concurrency. The BPEL
Service Engine can be tuned at either the domain level or the process level.
It is absolutely essential to know the nature of processes that are to be executed
in your infrastructure, for you to be able to tune it. Processes can be categorized
by the nature of their interfaces, for example, asynchronous, push based, or
synchronous. They can also be durable (long running) or transient (short lived).
Again, in any of these processes, there may be activities that are idempotent
(retryable, such as the Assign and Invoke activities) or invocations that are non-
blocking (happening in parallel). A process can also have a breakpoint wherein
its state is saved in the dehydration store or the state is not stored at all. All these
factors have to be taken into consideration when tuning the service engines.
