The LoanFlowPlus tutorial provides step-by-step instructions on setting up and using Oracle BPEL Process Analytics to monitor an Oracle BPEL Process Manager process flow.
The following topics are included in this chapter:
|
Note: The directory paths shown in this chapter follow Microsoft Windows conventions (using backslashes (\)). If you are running the tutorial on a Linux or Solaris operating system, modify the directory paths as required (using slashes (/)). |
To run the LoanFlowPlus tutorial, you must first deploy the LoanDemoPlus sample into Oracle BPEL Process Manager as described in the list that follows. In any step where it is mentioned, BPM_HOME is the Oracle home directory for Oracle BPEL Process Manager.
Make sure Oracle BPEL Process Manager Server is running.
For all files in the following directory, clear the read-only flag in the file properties:
BPM_HOME\integration\orabpel\samples\demos\LoanDemoPlusWithWorkFlow\LoanFlowPlus
From the command line, set the command path to the following directory:
BPM_HOME\integration\orabpel\bin
Run the obant command from the following directory:
BPM_HOME\integration\orabpel\samples\demos\LoanDemoPlusWithWorkFlow
Open the Oracle BPEL Process Manager Console, select default from the Domain box, then click Login.
On the Dashboard tab, make sure that the following processes are included in the Deployed BPEL Processes column:
CreditRatingService
LoanFlowPlusWorkFlow
StarLoanWithWorkFlow
UnitedLoan
|
Note: Leave Oracle BPEL Process Manager Server running for the duration of the tutorial. |
You insert sensors into the Oracle BPEL Process Manager LoanFlowPlus process flow, so that events are published to a JMS queue from which Oracle BPEL Process Analytics can capture them. Oracle BPEL Process Analytics uses the JMS queue to present the event metadata during composite event creation, and to capture the events in real time.
Use one of the methods described in the following sections to set up the event activity sensors:
Using the Preconfigured Event Activity Sensors
This method allows you to quickly move to the steps on using Oracle BPEL Process Analytics, but does not give you a complete understanding of what is involved in monitoring Oracle BPEL Process Manager events.
Using JDeveloper BPEL Designer
This is the preferred method. It provides a full demonstration of what is involved in monitoring Oracle BPEL Process Manager events.
Preconfigured event activity sensors are included in the LoanDemoPlus sample. If you do not want to use the tutorial to understand how to insert sensors into the process flow, proceed to: "Using Oracle BPEL Process Analytics to Model Events".
If you choose to insert event activity sensors using JDeveloper BPEL Designer, you need to insert the following sensors into the LoanFlowPlus process flow:
For the LoanRequest sensor, screenshots of how your window should look are provided for most steps. For the remaining sensors, screenshots are provided only when they vary substantially from the LoanRequest screenshots.
Before you can insert the sensors, you must load the LoanFlowPlus process into JDeveloper BPEL Designer.
This section includes the information about loading the process, inserting each of the required sensor actions and sensors, and deploying the modified LoanFlowPlus process as follows:
Follow these steps to load the process. In each step where it is mentioned, BPM_HOME is the directory specification for the Oracle home into which you installed Oracle BPEL Process Manager (on Microsoft Windows systems, for example, C:\OraHome_5).
Open JDeveloper BPEL Designer.
On the File menu, click New. The New Gallery dialog box opens.
In the Items box, select Application Workspace, then click OK. The Create Application Workspace dialog box opens.
Click OK.
In the Applications Navigator, select Application1.
On the File menu, click Open. The Open dialog box opens.
In the Open dialog box, specify the following file, then click Open.
BPM_HOME\integration\orabpel\samples\demos\LoanDemoPlusWithWorkFlow\LoanFlowPlus\LoanFlowPlusWithWorkflow.jpr
In the Applications – Navigator , expand LoanFlowPlusWithWorkflow, then Integration Content.
Double-click LoanFlowPlus.bpel.
The JDeveloper BPEL Designer interface should contain a panel in the Diagram View similar to Figure 4-1.

This section describes how to insert the first of the four sensors required for the tutorial. A sensor is composed of the attributes described in the following table:
The steps that follow describe how to insert the LoanRequest sensor.
Using these steps, you will create a sensor named LoanRequest on the Oracle BPEL Process Manager process activity named receiveInput. The structure of the event associated with that activity will be held in the activity variable named input, and the activity will be evaluated when it completes. At that time, the event structure will be published to the JMS queue as defined by the BPAPublisher sensor action (for the Oracle BPEL Process Analytics monitor to receive), and will be published to the database as defined by the BPMReportsPublisher sensor action (for the BPEL reports).
In the LoanFlowPlus diagram, double-click receiveInput. The Receive property sheet opens.
