(JDeveloper 11.1.1.7, WLS 10.3.6, SOA/BPM 11.1.1.7)
Following is a simple Application to demonstrate how to
Communicate between running process instances in Oracle BPM, using Events,
Signals and Correlation
Create a BPM Application with an Asynchronous process
Define a Business Object and payload as shown below
Modify the Business Object and add attributes as follows
Add another Business object as follows for identifying the
instance of the process we want to send a signal.
Create a process data object with the object type ‘ESCObject’
and make sure it is Auto Intialized.
Open the Start activity properties and create Data mappings
as follows and associate the Start activity payload to the process payload.
Open the Start activity Correlations property and Add a
correlation key as shown below.
Make sure the correlation has ‘Initiates’ as shown below
Drop a User activity after the Start and associate the data
mappings as shown below.
Create a new Event as shown below
Drop an Event Sub process in the ESC Process and set the
implementation type for the Start as Signal and associate data mappings as
shown below.
Define Correlations as shown below. Make sure the Mode is ‘Uses’.
Add an Update activity in the event sub process as follows.
Make sure Auto Initialize is
not checked for the payload in the Event Sub process
Create another process in the process to throw the Signals
for Stopping the process
Add a throw event after the Signal Start in the process as
follows and associate data mappings.
Make sure Auto Initialize is not checked for the process data
object in the Terminate Process
Testing
Login
to the EM Console and click on the Composite
Enter
data as follows for testing and click on ‘Test Web Service’
The
process now waits at the human task for the user to respond.
You can also see it in the BPM Workspace
Select
to test the other process to terminate the first process instance
Enter the correlation key data for the process
instance and click Test Web Service
The
process is now terminated and the user task in the BPM Workspace is Withdrawn
