Inspecting Process Variables during Simulation

During simulation, as each activity executes, you can inspect variable values in the Process Variables view. The values are those you loaded into Process Variables or into the simulation properties for receives, invokes, onMessage branches of picks and onEvent branches of event handlers. For information on loading and changing data values, see Supplying and Inspecting Sample Variable Data During Simulation.

Here is a recommended way to inspect variable values, by opening and closing variables as you need to.

1. Display the Process Variables view.

Tip: Display the list of variables with all variables closed. To close all variables, select a variable from the list, and select Close All from the right-mouse menu.

2. Start simulation. For details, see Simulating Execution of a BPEL Process.
3. Step to the first receive or onMessage branch of a pick activity. For more information, see Stepping to the Next Activity in a BPEL Simulation.
4. Notice that the variable in use is highlighted in the Process Variables list. The following example shows the buyerInfo variable highlighted.



5. Double-click the highlighted variable to open it.
6. Right-mouse click the variable and select View Data.
7. Step to the next activity to execute the current activity. The following example shows the normal result of variable processing.



8. Continue stepping through the simulation, inspecting variables as needed.
