4:33 a.m.
We are using version 5.1.0.M1. We have long-running processes (flows). They are
long-running because we have work item nodes that involve the user of our application to
do something. We are in the development cycle of our product and everything is going well.
I am trying to configure persistence and running into some issues.
I am to the point where our basic unit tests appear to be running fine with persistence
enabled both in the container (tomcat6) and in our unit testing environment
(ServletUnit).
We have unit tests that run the same test in multiple threads in parallel (the idea is to
try to expose thread safety issues), and these tests always fail. At the end of this
message, I have pasted a few of the different stack traces I have seen.
I expect that I have done something silly in the configuration, and I could use some help
in finding it. I am not sure if the problem is my configuration of JPA, Hibernate, the
DataSource, or if it is an interaction between what Drools is expecting and the details of
my configuration.
Thanks,
Rob Collins

What kind of thread safe tests are you doing?
if multiple threads modify the status of the process, only one of them will
commit the new status, and the other ones will rollback the transaction
because of a bad state.
Is that what you are looking for?

The idea of the tests is to ensure that our implementation is thread-safe. Each thread in
the test creates its own Drools session and executes its own workflow (which contains
actions and work items that involve user interaction that is simulated by the unit test).
This scenario tests the real-world case of our server handling sessions from multiple
users. There should NOT be cross-talk between these sessions. Without persistence,
everything works as expected. With persistence enabled, two sessions running in parallel
are enough to fail 100% of the time.
Each thread creates a session like this:
session = JPAKnowledgeService.newStatefulKnowledgeSession(getKnowledgeBase(),
null, getEnvironment());
The calls to getEnvironment() return the same value each time it is called called. Is this
right?
The environment is created like this:
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
environment = KnowledgeBaseFactory.newEnvironment();
environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
Any idea where I messed up?
Thanks,
Rob

What kind of thread safe tests are you doing?
if multiple threads modify the status of the process, only one of them will commit the new
status, and the other ones will rollback the transaction because of a bad state.
Is that what you are looking for?

We are using version 5.1.0.M1. We have long-running processes (flows). They are
long-running because we have work item nodes that involve the user of our application to
do something. We are in the development cycle of our product and everything is going well.
I am trying to configure persistence and running into some issues.
I am to the point where our basic unit tests appear to be running fine with persistence
enabled both in the container (tomcat6) and in our unit testing environment
(ServletUnit).
We have unit tests that run the same test in multiple threads in parallel (the idea is to
try to expose thread safety issues), and these tests always fail. At the end of this
message, I have pasted a few of the different stack traces I have seen.
I expect that I have done something silly in the configuration, and I could use some help
in finding it. I am not sure if the problem is my configuration of JPA, Hibernate, the
DataSource, or if it is an interaction between what Drools is expecting and the details of
my configuration.

yes the problem is the environment.. I saw that problem in the past..
you need to create a separate environment object per each session.

The idea of the tests is to ensure that our implementation is
thread-safe.
Each thread in the test creates its own Drools session and executes its own
workflow (which contains actions and work items that involve user
interaction that is simulated by the unit test).
This scenario tests the real-world case of our server handling sessions
from multiple users. There should NOT be cross-talk between these sessions.
Without persistence, everything works as expected. With persistence enabled,
two sessions running in parallel are enough to fail 100% of the time.
Each thread creates a session like this:
session =
JPAKnowledgeService.newStatefulKnowledgeSession(getKnowledgeBase(), null,
getEnvironment());
The calls to getEnvironment() return the same value each time it is called
called. Is this right?
The environment is created like this:
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
environment = KnowledgeBaseFactory.newEnvironment();
environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
Any idea where I messed up?
Thanks,
Rob

What kind of thread safe tests are you doing?
if multiple threads modify the status of the process, only one of them will
commit the new status, and the other ones will rollback the transaction
because of a bad state.
Is that what you are looking for?

We are using version 5.1.0.M1. We have long-running processes (flows). They
are long-running because we have work item nodes that involve the user of
our application to do something. We are in the development cycle of our
product and everything is going well. I am trying to configure persistence
and running into some issues.
I am to the point where our basic unit tests appear to be running fine with
persistence enabled both in the container (tomcat6) and in our unit testing
environment (ServletUnit).
We have unit tests that run the same test in multiple threads in parallel
(the idea is to try to expose thread safety issues), and these tests always
fail. At the end of this message, I have pasted a few of the different stack
traces I have seen.
I expect that I have done something silly in the configuration, and I could
use some help in finding it. I am not sure if the problem is my
configuration of JPA, Hibernate, the DataSource, or if it is an interaction
between what Drools is expecting and the details of my configuration.
Thanks,

You were right the first time - I am sharing the environment between multiple sessions.
That is easy for me to fix.
Can I share the EntityManagerFactory, or should I create one for each session?
Thanks,
Rob

oh.. sorry.. you are creating a new env per each session.. but the problem is related with
that..
I will review that and let you know.

yes the problem is the environment.. I saw that problem in the past..
you need to create a separate environment object per each session.

The idea of the tests is to ensure that our implementation is thread-safe. Each thread in
the test creates its own Drools session and executes its own workflow (which contains
actions and work items that involve user interaction that is simulated by the unit test).
This scenario tests the real-world case of our server handling sessions from multiple
users. There should NOT be cross-talk between these sessions. Without persistence,
everything works as expected. With persistence enabled, two sessions running in parallel
are enough to fail 100% of the time.
Each thread creates a session like this:
session = JPAKnowledgeService.newStatefulKnowledgeSession(getKnowledgeBase(),
null, getEnvironment());
The calls to getEnvironment() return the same value each time it is called called. Is this
right?
The environment is created like this:
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
environment = KnowledgeBaseFactory.newEnvironment();
environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
Any idea where I messed up?
Thanks,

What kind of thread safe tests are you doing?
if multiple threads modify the status of the process, only one of them will commit the new
status, and the other ones will rollback the transaction because of a bad state.
Is that what you are looking for?

We are using version 5.1.0.M1. We have long-running processes (flows). They are
long-running because we have work item nodes that involve the user of our application to
do something. We are in the development cycle of our product and everything is going well.
I am trying to configure persistence and running into some issues.
I am to the point where our basic unit tests appear to be running fine with persistence
enabled both in the container (tomcat6) and in our unit testing environment
(ServletUnit).
We have unit tests that run the same test in multiple threads in parallel (the idea is to
try to expose thread safety issues), and these tests always fail. At the end of this
message, I have pasted a few of the different stack traces I have seen.
I expect that I have done something silly in the configuration, and I could use some help
in finding it. I am not sure if the problem is my configuration of JPA, Hibernate, the
DataSource, or if it is an interaction between what Drools is expecting and the details of
my configuration.
Thanks,

I think that you can share it.. but just in case take a look at the official
JPA documentation to be sure about it.

You were right the first time - I am sharing the environment between
multiple sessions. That is easy for me to fix.
Can I share the EntityManagerFactory, or should I create one for each
session?
Thanks,

oh.. sorry.. you are creating a new env per each session.. but the problem

I will review that and let you know.

you need to create a separate environment object per each session.

The idea of the tests is to ensure that our implementation is thread-safe.
Each thread in the test creates its own Drools session and executes its own
workflow (which contains actions and work items that involve user
interaction that is simulated by the unit test).
This scenario tests the real-world case of our server handling sessions
from multiple users. There should NOT be cross-talk between these sessions.
Without persistence, everything works as expected. With persistence enabled,
two sessions running in parallel are enough to fail 100% of the time.
Each thread creates a session like this:
session =
JPAKnowledgeService.newStatefulKnowledgeSession(getKnowledgeBase(), null,
getEnvironment());
The calls to getEnvironment() return the same value each time it is called
called. Is this right?
The environment is created like this:
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
environment = KnowledgeBaseFactory.newEnvironment();
environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
Any idea where I messed up?
Thanks,

What kind of thread safe tests are you doing?
if multiple threads modify the status of the process, only one of them will
commit the new status, and the other ones will rollback the transaction
because of a bad state.
Is that what you are looking for?

We are using version 5.1.0.M1. We have long-running processes (flows). They
are long-running because we have work item nodes that involve the user of
our application to do something. We are in the development cycle of our
product and everything is going well. I am trying to configure persistence
and running into some issues.
I am to the point where our basic unit tests appear to be running fine with
persistence enabled both in the container (tomcat6) and in our unit testing
environment (ServletUnit).
We have unit tests that run the same test in multiple threads in parallel
(the idea is to try to expose thread safety issues), and these tests always
fail. At the end of this message, I have pasted a few of the different stack
traces I have seen.
I expect that I have done something silly in the configuration, and I could
use some help in finding it. I am not sure if the problem is my
configuration of JPA, Hibernate, the DataSource, or if it is an interaction
between what Drools is expecting and the details of my configuration.
Thanks,
