[rules-users] Timer Cron reevaluating same facts again and gain
I have a rule which fires let's say every 5 secs. I have thread which continously infuse facts to ksession simultaneoulsy. For example, At 5th sec, I have 500 matching facts, with total 1000 facts Before the next invocation I infuse another 1000 facts. So, at 10th sec, Rule considers whole working memory including previously evaluated facts. I expected only new facts to be evaluated as I'm running stateful session -- View this message in context: http://drools.46999.n3.nabble.com/Timer-Cron-reevaluating-same-facts-again-and-gain-tp4019422.html Sent from the Drools: User forum mailing list archive at Nabble.com.___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

How do you determine when a "fact is evaluated"?

"I expected only new facts to be evaluated as I'm running stateful session" It only works this way if you let your session alive in a separate Thread, using fireUntilHalt(). If you use fireAllRules() (by instance each 5s), then yes, everything will be re-evaluated, just as if it were a new session.

I'm maintaining count for each successful match. So, let's say, if in next phase there are another 500 successful facts, the count becomes 1500. -- View this message in context: http://drools.46999.n3.nabble.com/Timer-Cron-re-evaluating-same-facts-again-and-again-tp4019422p4019426.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Timer Cron reevaluating same facts again and gain
I'm using fireUntilHalt(). Then too it's happening I can't retract facts, as there might be other rule to be evaluated for facts. ( which too have cron timer. So If I remove facts and when that rule becomes active, there would be no firing) -- View this message in context: http://drools.46999.n3.nabble.com/Timer-Cron-re-evaluating-same-facts-again-and-again-tp4019422p4019427.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

In consequence part of the rule, there is a method call which increment the count by one for each successful match -- View this message in context: http://drools.46999.n3.nabble.com/Timer-Cron-re-evaluating-same-facts-again-and-again-tp4019422p4019429.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Timer Cron reevaluating same facts again and gain
There you are not counting "evaluations of facts" but "executions of a rule". If you have a timer on a rule with timer(5s 5s) it will fire for each and every matching fact or combination of facts, as long as this match continues for this particular fact or fact combination. -W On 29/08/2012, rvkhakhkhar1 wrote: > In consequence part of the rule, there is a method call which increment the > count by one for each successful match > > > > -- > View this message in context: > http://drools.46999.n3.nabble.com/Timer-Cron-re-evaluating-same-facts-again-and-again-tp4019422p4019429.html > Sent from the Drools: User forum mailing list archive at Nabble.com. > ___ > rules-users mailing list > rules-users@lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Timer Cron reevaluating same facts again and gain
That means, a rule with timer don't remeber for which facts it has executed consequence part previosly and when its time arrive it just execute consequence part on available facts. I checked using AgendaListner, just after rule fire(afterActivationFired) isActive becomes false, but for the next time in beforeActivationFired the same fact's isActive become true. -- View this message in context: http://drools.46999.n3.nabble.com/Timer-Cron-re-evaluating-same-facts-again-and-again-tp4019422p4019437.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

A rule never "remembers" anything, with or without timers. A rule with a timer results in an activation which is a combination of a rule and a tuple of matching facts; one rule may have any number of pending activations at any time. An activation of a rule with a timer will become reactivated (after having been fired before) when the timer fires again and the rule condition still holds for the associated tuple of fact. -W > I checked using AgendaListner, just after rule fire(afterActivationFired) > isActive becomes false, but for the next time in beforeActivationFired the > same fact's isActive become true. > > > > -- > View this message in context: > http://drools.46999.n3.nabble.com/Timer-Cron-re-evaluating-same-facts-again-and-again-tp4019422p4019437.html > Sent from the Drools: User forum mailing list archive at Nabble.com. > ___ > rules-users mailing list > rules-users@lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
