Re: [jboss-user] [jBPM] - How to handle failed processes/states due to server crashes?

by Michael Rinne

Michael Rinne [http://community.jboss.org/people/mrinneL1] replied to the discussion "How to handle failed processes/states due to server crashes?" To view the discussion, visit: http://community.jboss.org/message/555485#555485 -------------------------------------------------------------- Hi, Concerning exception handling, I saw that advice to take care of exceptions in the user code a couple of times in this forum, but I am not totally convinced that this is capable to handle all cases that arise in BPM. Let us assume I have a process definition containing the sequence state1 -> task1 -> task2 -> state2. Let us further assume there is some sort of dependency between task1 and task2, i.e. if task2 fails we have to perform some kind of undo for task1. If I handle exceptions within the user code for task2 I am not able to undo task1, because I do not want task2 to know about task1. For the same reason, I do not want to combine task1 and task2 into a single task. The solution in jpdl 4 seems to be adding another transition from task2 to a task "undo_task1" and any exception in task2 will make sure that we take the transition to "undo_task1". Another transition from "undo_task1" will lead back to state1 and of course we add a decision in order to prevent processing from taking this circle endlessly. However, an exception-handler as provided by jpdl 3 seems to be a convenient way to handle most exceptions on a BPM scale, although it will most likely not be as flexible as the explicit solution sketched above. What are you opinions on this? Does anyone have a better idea on how to do exception handling on BPM scale with jpdl 4? Thanks, Michael -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/555485#555485] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

To view the discussion, visit: http://community.jboss.org/message/555471#555471 -------------------------------------------------------------- I have a similar issue and I think there is a race condition between the DispatcherThread that handles the execution of async Messages/Jobs and the main-Thread. Both alter data in the JBPM4_JOB table, I think this is what is going on: 1. main-Thread is running along, minding his own business and creates a hibernate-Session 2. DispatcherThread wakes up and also creates a hibernate-Session accessing data in the JBPM4_JOB table 3. DispatcherThread did its work and removes the Job data from the JBPM4_JOB table 4. main-Thread ends an execution and deletes the execution related data from the JBPM4_JOB table, since the same data have been altered by different session there is an exception at this point -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/555471#555471] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Also note you had "exectution" and "execution" in the code fragment. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/555458#555458] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
