[jboss-user] [jBPM] - Sharing database between multiple JBPM runtimes

baecks [http://community.jboss.org/people/baecks] created the discussion "Sharing database between multiple JBPM runtimes" To view the discussion, visit: http://community.jboss.org/message/610492#610492 -------------------------------------------------------------- Hello, I have JBPM 3 deployed in a number of JBOSS AS 5.1. I set up the application server and JBPM to use one single MYSQL database for persistence (--> only one shared database). The idea is to use the database as a "synchronization mechanism" between the various JBPM instances. I'm now trying to find out if this is supported by JBPM 3 (& Hibernate) and whether the following use-cases will work: 1/ New ProcessDefinition - Create a new ProcessDefinition on one server and store it into the database. - On a second server, obtain the list of ProcessDefinitions using the JBPM API (GraphSession::findAllProcessDefinitions). Will the new ProcessDefinition be in the list? 2/ Resume process instance - On one server, start a new process instance and store the state into the database - On a second server, retrieve the process instance (based on instance ID) and make the process continue (signal) Is this possible? The idea is to have multiple JBPM run-times "virtually" working together without a need for JBOSS AS clustering, Hibernate caches etc. I believe Hibernate does some caching (don't know exactly how) and I fear this might cause this setup not to work (completely). Any info on this would also be welcome. All answers & help are very appreciated. Thanks, Sven. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/610492#610492] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
