[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
Re: [rules-users] Understanding Rules Firing Sequence
The learning is : for your case, where all your row in your table have an implicit priority and business logic, yes, don't hope that drools engine will guess that by itself. As far i understand, you expect the rules to trigger from top to bottom (or most specific to less), and stop when a rule has fired. Your problem is that you have a lot of rules with shared conditions which have different (and conflicting) actions. Using specificity strategy is a good idea (never tried, but it looks great), but that won't prevent other (less specific) rules to fired after the first specific rules has fired. In addition to specific strategy, you have to add a condition to test if your fees field is set or not. If you add a common column (you can hide it under guvnor) that test fees == null, then the first rule exec (so the most specific one) will set this field and prevent other rules to fire. So, please let drools manage the rules firing, but tune your rules/facts to fit your specific business logic, under drools (or any other expert-system) constraints. - Mail original - De: tanug tanu.gu...@rupeelog.com À: rules-users@lists.jboss.org Envoyé: Mardi 28 Août 2012 13:44:25 Objet: Re: [rules-users] Understanding Rules Firing Sequence Thanks everyone for your suggestions. so, basically, the learning is : I should not leave rule firing to Drools, and have a proper priority and exit condition. And, I cannot rely on specificity for rule selection (i was so hoping it would work) Thanks again, best regards Tanu -- View this message in context: http://drools.46999.n3.nabble.com/Understanding-Rules-Firing-Sequence-tp4019409p4019416.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
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. NB : I hope you have something to clean up your facts too ! - Mail original - De: rvkhakhkhar1 rvkhakhk...@gmail.com À: rules-users@lists.jboss.org Envoyé: Mercredi 29 Août 2012 11:58:51 Objet: [rules-users] Timer Cron reevaluating same facts again and gain I have a rule which fires let's say every 5 secs.

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 rvkhakhk...@gmail.com 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
