[jboss-jira] [JBoss JIRA] Commented: (JBPM-886) change ejb timers from SLSB to an entity bean approach

[Tom Baeyens (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBPM-886?page=comments#action_12379555 ] 
            
Tom Baeyens commented on JBPM-886:
----------------------------------

the timer entity bean should leverage the existing JBPM_JOB table.  most difficult part will be to do a flush between the moment when a new job is persisted with the hibernate session and then you need to flush before loading that same record as an  entity bean to schedule the ejb timer on it.

> the problem is that all the timers are put on a single slsb.  so we have to loop through all the timers to cancel or find one.  that is a bottleneck.
> we need to change that approach to the use of entity beans.  1 entity bean per job.  so that we can put queries for jobs and that way have a more efficient way of finding and cancelling ejb timers.
