LocalTaskService keep using one Entity Manager, Breaks when Database is Restarted

thomas.setiabudi Aug 12, 2013 11:33 PM

Hi,

This is similar post to https://community.jboss.org/thread/231488?tstart=0

Only that it discuss about LocalTaskService here

I use JBPM5.4.Final, and Drools-Spring 5.4.Final in a Web Application.

I create Stateful Knowledge Session and LocalTaskService in the Spring config file, they are created once for the rest of the web application life.

Everything works fine, until the Database Server, MS SQL Server 2008, is restarted.

Which then break the Stateful Knowledge Session and LocalTaskService.

After looking at the LocalTaskService code here
https://github.com/droolsjbpm/jbpm/blob/5.4.x/jbpm-human-task/jbpm-human-task-core/src/main/java/org/jbpm/task/service/local/LocalTaskService.java#L52-L55

Local Task Service has TaskServiceSession and then TaskServiceSession has TaskPersistenceManager which contain an EntityManager.

The problem is this EntityManager is acquired from EntityManagerFactory just exactly once.

when the database connection is no longer valid (Because of Database Server restart), it will still use the same EntityManager which will of course throw exception.

My question is, is it a bug? or I use these LocalTaskService Wrongly?

Currently, to keep my application running, I create another class that implements TaskService, and have all the code just like LocalTaskService, the difference is I add a check before doing anything about the task.

This is a sample code:

public void addTask(Task task, ContentData content) {
                    checkEntityManagerFactory();
                    session.addTask(task, content);
          }

and the checkEntityManagerFactory() implementation:

public void checkEntityManagerFactory() {
                    if (session != null) {
                              try {
                                        Query query = session.getTaskPersistenceManager()
                                                            .createNewQuery("SELECT 1 FROM Task WHERE id = 0 ");
                                        query.getResultList();
                              } catch (Throwable e) {
                                        session = service.createSession();
                              }


                    } else {
                              session = service.createSession();
                    }
          }

execute simple select query, when that query throws exception, that means its time to get new EntityManager which in this case is create new TaskServiceSession.

Is it the correct way to do this?

Will this issue fixed in JBPM 6 ?

Any help is appreciated.

Regards,

Thomas Setiabudi

swiderski.maciej Aug 13, 2013 1:10 AM (in response to thomas.setiabudi)

In general, TaskServiceSession object is request scoped object, meaning it shall be created and destroyed on every request. Although LocalTaskService caches it and that is the main reason why LocalTaskService is not thread safe. So to workaround the problem you would need to create LocalTaskService per request which is lightweight enough to do so and that should resolve the problem.

When it comes to ksession, as far as I can tell it does not have issue like LocalTaskService as ksession manages entity manager on command level. Every operation is a command that will be managed independently within transaction and entity managers will be closed and cleaned on transaction completion. What's you ksession strategy? Do you use single session or many sessions? if many make sure you use dedicated environment objects for every ksession.

Hi Maciejs,

I use a single session strategy, so I created only 1 LocalTaskService too, does it mean that it is not threadsafe this way?

Should I stick to the Many Session and Many LocalTaskService to get threadsafety?

arif.mohammed Apr 4, 2014 1:28 AM (in response to thomas.setiabudi)

Hi Thomas,

    Did you got any solution for thread safety issue ?

    Iam also using single ksession for entire application and I could use 1 LocalTaskService for each thread but the issue is with LocalHTWorkItemHandler. It need LocalTaskService and LocalHTWorkItemHandler need to be registered on ksession following is the code. It look like chicken and egg problem, am I doing anything wrong here ? Maciej can you please help us ?

humanTaskHandler = new LocalHTWorkItemHandler(localTaskService, ksession); //ksession is singleton object
ksession.getWorkItemManager().registerWorkItemHandler("Human Task",humanTaskHandler); // Do I need to register this handler for every thread ??

simply extend the handler to create instance of LocalTaskService on every invocation of the important methods and the listener.

org.drools.container.spring.beans.persistence.DroolsSpringJpaManager.endCommandScopedEntityManager has similar problem, after em.close failure, operation can not continue anymore, It will throw exception: javax.persistence.PersistenceException: org.hibernate.SessionException: Session is closed! I have to restart tomcat。

appScopedEntityManager is application scope, so maybe have similar problem,

below is exception trace:

8. Re: LocalTaskService keep using one Entity Manager, Breaks when Database is Restarted

arif.mohammed Apr 19, 2014 2:42 PM (in response to lijiangt)

It seems to be there are always problems with transactions with jBPM. I agree as per the documentation it is said that we can configure it in different environments, It would be great if jBPM team can enhance the documentation for configuring in different types of environments Or I might have not looked in proper place. Initially I had some problems with jBPM5.4.0 + Spring + tomcat + bitronix tx mgr, then I am forced to move to jBoss app server. I started using jBPM5.4.0 + Spring + jBoss7.1.1 dont ask why spring layer if I am already in JEE environment, I have some project constraints. Later with some changes in configurations I am able to work with jBPM5.4.0 + Spring + Local transactions (for unit testing) but Iam not able to succeed with jBPM5.4.0 + Spring + JTA + Bitronix/Atomikos tx mgr. Now at last when I am in process of upgrading to version 6 I have problems with both jBPM6 + Spring + Local transactions and jBPM6 + Spring + JTA + Bitronix/Atomikos for oracle DB, However I am able to succeed atleast in deployment with jBPM6 + Spring + jBoss7.1.1.

To cut short the description I always face problems with transactions when not using jBPM + jBoss There seems to be already there are un-resolved threads related to using jBPM outside of jBoss container
