JBPM5 configuration for Oracle in production

lescarret Apr 7, 2011 4:24 AM

Hello,

I want to deploy JBPM in production using persistence of processes and human tasks in an Oracle database. I have changed in the persistence.xml and hiberante.cfg.xml file the H2 database connection configuration by Oracle configuration.

We encounter the following exceptions while listing Processes in the jbpm-console :

Caused by: javax.persistence.PersistenceException: [PersistenceUnit: org.drools.persistence.jpa] Unable to build EntityManagerFactory

...

Caused by: org.hibernate.HibernateException: The chosen transaction strategy requires access to the JTA TransactionManager

What is the jar involved ?

The JBPM 5 involved a lot of components. For production use, we want a minimal deployment at first time.

We want to cut dependency with a drools-guvnor repository, and obtain the processes definition from file system.

How can we achieve that ?

Can we change only the ChangeSet.xml in jbpm-gwt-core-5.0.0.jar ?

Thanks in advance,

You can use 'Guvnor' or filesystem (http://community.jboss.org/message/587133#587133)

You need to modify the persistence (process/task/audit ) details for Oracle.
Do you plan to use JBPM-Console (e.g, http://community.jboss.org/people/bpmn2user/blog/2011/02/26/orcale-integration-with-jbpm5) or do you plan to use it using api calls (e.g, http://community.jboss.org/people/bpmn2user/blog/2011/04/03/jbpm5-human-task-api-usage-example) ?

Thanck you very much for your answer : it helps.
We plan to use the API for integration purpose and the jbpm-console as a back office application.
