Hi, I'm thinking about how to activate/deactivate parts of the rule set during runtime. I'm doing some brainstorming about that and would be happy, if I could get more experienced input. ;-) What I want to do: I have several rules where I process 4 different objects separate and some rules processing combinations of the 4 objects. Now I want to be able to activate/decativate the processing of e.g. one of the objects at runtime when my application receives a specific command. How can I do that? My thoughts: 1.) I thought about maybe inserting a fact that states if the processing of a object is disabled. If I'm including the fact in the rules conditions, the rules including the specific object are prevent from firing. But I could imagine that is results in performance costs because its always checked in every rule condition if the specific processing is (de)activated. 2.) Is it possible to (de)activate the execution of rules for a specific object using some grouping... 3.) Is it possible to rebuild the knowledge base during runtime using templates and incremental change-set processing. Or something alike... (Because the separate processing of the 4 objects is kind of identical.) Thanks for any input! :) Tina _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

There is the little documented "enabled" attribute too... http://drools-java-rules-engine.46999.n3.nabble.com/executing-ruleflow-wi... But agenda group would provide what you're after (unless you need a single rule in two groups). 2010/10/28 Wolfgang Laun <wolfgang.laun(a)gmail.com <mailto:wolfgang.laun@gmail.com>> Look at the agenda-group attribute. Setting the focus makes just the group's rules eligible for firing. Falling back to the "MAIN" (default) group is automatic, after all group rules have been "exhausted". I think this is what you mean with your #2 Solution 1 could be used, too; efficiency's not a problem. -W -W On 28 October 2010 02:08, Tina Vießmann <tviessmann(a)stud.hs-bremen.de <mailto:tviessmann@stud.hs-bremen.de>> wrote: Hi, I'm thinking about how to activate/deactivate parts of the rule set during runtime.
