Invoke OnMessage activity of a running BPEL process instance...

Question

Hi,
We are using Oracle BPEL 10.1.2.0.2. I am willing to invoke a running instance of a BPEL process (Timer) in following scenario:
The 'Timer' BPEL Process gets initiated, and logs its instance-id into the database
'Timer' process waits on an OnMessage activity for another process to invoke it
Another BPEL process selects the instance-id of 'Timer' process from the database
The question is: in the above scenario, can the 2nd BPEL process invoke the OnMessage activity of the Timer BPEL process. I did search through the Locator API but was unable to find a method which can invoke a running BPEL instance.
I am not willing to use correlation here because correlation does not guaranty the invocation of the target BPEL process and also does not generate any error if no instance gets invoked.
Thanks,
Upendra Jariya.

JDK 5.0 includes sample code for java.lang.management API in the <JDK>/demo/management directory. In particular, demo/management/VerboseGC demonstrates how to use the java.lang.management API to print GC statistics in a similar way to -verbose:gc.
You can reference this demo program and make appropriate modification, for example, just to call java.lang.management.MemoryMXBean.setVerbose() operation to turn on/off the -verbose:gc tracing.
