Class BatchStepTrigger

java.lang.Object

org.kuali.ole.sys.context.BatchStepTrigger

public class BatchStepTrigger
extends Object

BatchStepTrigger writes .run files containing a job name and step name for BatchContainerStep to read. It loops and sleeps until either a .success or an .error file is written for the Step. Once a result file is found tt logs the results and exits. BatchStepTrigger also checks for BatchContainerStep's .runlock file. If it doesn't find one (indicating the batch container is not running) it exits. BatchStepTrigger adds a ConsoleAppender to its Logger if one hasn't been configured. Note that this class runs without starting the SpringContext. KFS Services and Beans are not available for use.

Method Detail

main

public static void main(String[] args)

BatchStepTrigger is instantiated for each step in a brte script. The value used when exiting the system tells the brte script how to handle failures. 0: okay, 4: the step returned false, 8: an exception occurred in the execution of the step or the trigger - verify that the batch container is running, exit with an 8 if not - for each step - write a RUN semaphore file - wait and listen for a result file (either SUCCESS or ERROR) - if the result file is null the batch container is not running so remove the run file and exit with an 8 - if the result file is an ERROR - if the file is EMPTY remove the result file and exit with a 4 - otherwise log the error contained in the result file, remove the result file, and exit with an 8 - otherwise remove the result file and exit with a 0
