[Messaging, JMS & JBossMQ] - What does the MaxMessage element set up in the proxy-factory
by alzamabar-vu
Hi, I'm going through the configuration for MDBs in the conf/standardjboss.xml file. The configuration for Standard MDBs contained within the <proxy-factory-config> element contains, amongst the others, the following elements:
1) MaximumSize
2) MaxMessages
I'm trying to keep our JBoss server *busier* than it is at the moment when sending out SMS messages trying to achieve a higher performance throughput by increasing the number of messages which can be processed concurrently. Ideally I'd like 20, 30, etc (to be fine tuned) MDBs to be able to serve concurrently 20, 30, etc requests and I'm not sure whether I should change 1), 2) or both.
>From what I could guess, 1 is the number of MDBs that the container keeps in the pool, 2) is the number of concurrent messages. Is that right?
Thanks for any response.

[JBoss jBPM] - Re: EJB3 Stateless Session Bean and jbpm-enterprise.ear
by crussell42
Martin, thank you so very much.
Ronald man I don't have any idea what you were trying to convey.
The ONLY difference from what I had already tried was the silly removal of the
| <property name="jta.UserTransaction">java:comp/UserTransaction</property>
|
If it is there, the deleteJobsForProcessInstance throws the exception.
Silly me I figured that the flag isTransactionEnabled would override ever even reading this property?
So just to ease others pain and suffering here is the jbpm.cfg.xml and hibernate.cfg.xml that work for me for postgres.
Also this little snippet is important as well when creating a JbpmContext from your own config xml string. The combination of these 3 things finally does seem to work.
| /**
| * Get jbpm context. Note that we must set the session from the DbPersistenceService
| * or hibernate will fail.
| */
| private JbpmContext getJbpmContext() {
| //JbpmContext jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| DbPersistenceService persServ=(DbPersistenceService)jbpmContext.getServices().getPersistenceService();
| jbpmContext.setSession(persServ.getSessionFactory().getCurrentSession());
| return jbpmContext;
| }
|
jbpm.cfg.xml (actually just an xml string in my program)
