For an even less technical solution you could have a person with a big stick standing behind the users... I think what we are all wondering is why you want to limit the number of rules!

Re: [rules-users] rule limit
thanks for all of the responses, fun to read :) Sorry I thought it was pretty strait forward question. I would assume somehow the parser 'knows' how many rules are in a drl file I do not want an over ambitious user to just create rule after rule after rule (though I suppose he could technically do a lot even in one rule) rule a //1 when then end rule b //2 when then end rule c //3 when then end and so on... -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-rule-limit-tp3394660p3400312.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

But when it comes to compiling/loading the rules, you can of course check the number of rules and issue an error message if it exceeds your limit. See answer by Davide Sottara for technical details. However I'm still not convinced that this rather technical measure will make your life easier in the long run. Still having the impression that educating the user of your system to find a useful structure in their rules will pay off more than just putting up road closed signs.

Re: [rules-users] rule limit
Hi Slyfox, nice to read you. Am 05.10.2011 23:49, schrieb slyfox: is this something I missed in the doc As you are talking about the doc, it seems you have a particular part of the solution already in mind (the product/tool you'd like to use to enforce the size limit). Up to now, you did not describe these ideas anywhere. If you really expect anyone to help you, please let us know your actual use case and what you have thought up so far. It is simply not possible to find a quality answer in reasonable time without this knowledge -- finding the correct answer would involve a lot of guessing what you *really* want to know and then answering the guessed question(s). When asking a very broad question like can it be done, the best you can expect to get is a very broad answer (Yes, it can be done in this case). or would you mind pointing me in the direction of how to accomplish this? If you give more details on what you're trying to *achieve*, I promise to give it a try. If not, oh well, ehm, let me put it like this: as you're certainly storing the file on some media like a hard disk which cannot be unlimited in capacity, the file it holds is also implicitly limited in the number of rules in that file. Of course, this is absolutely not the answer you were looking for, but hey, how can one know better with that little information you gave first hand? It's all good, and I'd really like to help you, but please please please allow me and the fellow list members to get a clue what problem you're actually trying to solve. Describe what you're trying to build, how the problem you're experiencing surfaced, maybe what you already tried to solve it, how you think a rule number limit could solve your problem, these sorts of things.

Re: [rules-users] rule limit
As far as I know, the parser does not check the number of rules in a DRL Maybe you could do something like this: (i) use a KnowledgeBuilder to load the DRL resource; (ii) before you add the packages to the knowledgeBase, iterate over kBuilder.getKnowledgePackages() to find the package generated from your DRL; (iii) use getRules().size() on the package to check if the number of rules exceeds your desired threshold D. -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-rule-limit-tp3394660p3398277.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
