Capturing and acting on different return codes

This recipe shows how we can use the return codes from a child job to control the process flow in a schedule more effectively.

Getting ready

Open the job jo_cook_ch11_0050_ChildReturnCodes. You will see that it is a simpler version of the job from the previous exercise.

How to do it…

We will begin by printing the return code from a child job.

Printing return code

1. Add a tJava component with the following code:

   System.out.println("Return code is: "+((Integer)globalMap.get("tRunJob_1_CHILD_RETURN_CODE")));

2. Link from the task to the tJava component using OnSubjobOk.
3. Run the job—you will see that the return code is 0.

   Setting the return code

4. Double-click on the child job to open it.
5. Add a tDie component, and link it to the tJava component using OnSubjobOk.
6. Open the tDie component, and change the code to 4 . Now return to the calling (parent) job.
7. Open the component tab for the task, and untick Die on error.
8. Run the job—...
