Alright. So do I have to worry about contamination between rule flows. Consider the following scenario: 1) Instantiate Fact Model A with property A = 10. 2) Insert Fact Model A into Working Memory 3) Start Process A. 4) Instantiate second instance of Fact Model A with property A = 20. 5) Start Process A again.
So are there now two separate instances of Fact Model A in working memory or is there still only one instance and property A has been updated to 20? Will process B find the correct value (20)? Is it thread safe? Will unused fact objects hang around forever? Sorry if I'm being a little thick about this. Maybe I'm worrying about nothing. Thanks for your response. >>> JeffMax <[email protected]> 2/18/2011 11:31 AM >>> My experience has been (and I believe the expected behavior of stateful sessions) is that the state of your working memory will not be cleaned up between flow executions. If,for example, one flow execution inserts a new fact into working memory, then a subsequent flow execution would see that fact in working memory. For my requirements, which was to use Drools-Server as a stateless, request - response server, with no shared state between requests, it was necessary to use a stateless session. - Jeff -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/RuleFlow-only-calling-first-RuleFlowGroup-when-called-through-drools-server-tp2514244p2527353.html Sent from the Drools - User mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list [email protected] https://lists.jboss.org/mailman/listinfo/rules-users ------------------------- Statement of Confidentiality This message (including attachments) may contain confidential or privileged information intended for a specific individual or organization.
