Question on use of Timer node in rule flow

by Alan.Gairey＠tessella.com

I'm currently experimenting with including a Timer node within a rule flow. My question is: what (if any) runtime state information is persisted by Drools Flow for a Timer node? I can recreate a session via a call to JPAKnowledgeService.loadStatefulKnowledgeSession, but if a process instance was previously on a Timer node, will it start from where it left off, or will the Timer delay start from the beginning again? For example, if I have a Timer node with a delay of 7 days, but the application is stopped / crashes after 6 days, then when I recreate my session, will the Timer node just wait 1 more day, or will the delay of 7 days start from scratch? Thanks in advance for any help, Alan

Flow and Rules Together - Best practice question

by J Michael Dean

Have been working solely with rules and have now created an overall rule flow that has enabled me to eliminate parts of the conditions of many rules, because the rules are in rule flow groups. For example, if the glucose value must be below 40 to get into a rule flow group called "Below 40", then I do not need to check that the glucose is below 40 in the condition of every rule in the group. I have noticed, however, that when a fact is inserted, it appears to activate all rules for which the conditions match, even though the majority of the rules are not in the rule flow group. I am interpreting this as simply activating everything applicable, taking advantage of the Rete, and then the activated rules are filtered by rule flow group. Is this a correct interpretation? The corollary question is whether I am using best practice by eliminating "redundant" conditions from my rules, or whether I should include in those conditions the constraints that were determining whether the rule flow group becomes active. If this scaled up to one to two thousand rules, would the activations and filtering be more costly? Thanks for any advice. My colleagues and I were very happy to eliminate the redundant conditions because it makes our rules look simpler, but now concerned may be going down wrong track. - Mike

Re: [rules-users] rules-users Digest, Vol 39, Issue 45

by Nilima R

Hi In drools in deployment we get the below link. http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/xxxx... We need to include this in properties file in application wherein this URL is mentioned. How can one protect unauthorized access to this URL as the whole set of rules can be viewed for this .

If your field is called "foo", then should have a method in the class representing your fact, such as: boolean getFoo(){ return <condition> ? ! (<expression>) : <expression>; } Basically, <condition> could be a global parameter (public static final) or a static or regular method call. <expression> could depend on other attribute values, and so on. You can then write your CEs with a test such as foo == true But I think this is closely related with that other question you have posted. -W On Wed, Feb 17, 2010 at 9:32 AM, djb <dbrownell83(a)hotmail.com> wrote: > > Hi Wolfgang, > > Sure, I know de Morgan's laws, but I'm not asking how one can negate a > condition... > > I'm asking how one can either negate or not negate, based on a test... and > whether I'm going to have to split my spreadsheet/rule-template into 2, > (i.e. 1 for "may not be" rules, 1 for "must be" rules). > > My spreadsheet has a field that in Java would be expressed as field ? > !finalResult : finalResult > > But in DRL, it seems the lack of a ternary operator means I have to split > my > rule-set, and I'm just checking if this is the case. > > -Daniel > > -- > View this message in context: > http://n3.nabble.com/Negating-a-result-tp212559p212656.html > Sent from the Drools - User mailing list archive at Nabble.com. > _______________________________________________ > rules-users mailing list > rules-users(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > -------------- next part -------------- An HTML attachment was scrubbed...

And my rules have about 7 conditions, none of which are mandatory. And that is actually the source of all my problems: that the conditions are optional. If I set up a few logical relationships, there is nothing specific I am testing on, which gives a single expression I can test in a function. In procedural programming, I check each of the 7 conditions optionally, and then I apply my ternary operator to the final result. But here I can't do that, because the condition is made up of all the little conditions that may or may not be applicable. PS. Ok, so I see from the other thread that a rule template is meant to place whatever text you give it, like a text pre-processor. I'll see if that is correct, thanks. I thought it might not be, because if you provide a blank cell, it deletes your entire condition, instead of providing a "" or a null, like you'd expect from a text pre-processor. -- View this message in context: http://n3.nabble.com/Negating-a-result-tp212559p212797.html Sent from the Drools - User mailing list archive at Nabble.com. ------------------------------ Message: 3 Date: Wed, 17 Feb 2010 11:33:14 +0100 From: Wolfgang Laun <wolfgang.laun(a)gmail.com> Subject: Re: [rules-users] Negating a result To: Rules Users List <rules-users(a)lists.jboss.org> Message-ID: <17de7ee81002170233s62e0353fs50d439c532c75e82(a)mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" On Wed, Feb 17, 2010 at 11:02 AM, djb <dbrownell83(a)hotmail.com> wrote: > > Ok, so I see from the other thread that a rule template is meant to place > whatever text you give it, like a text pre-processor.

Drools Guvnor problem after crash..

by Tharakesh Siddalingaiah

Hello, I am not able to see/edit rules in Drools Guvnor (5.0.0.M5) after JBoss crash. We are using SQL Server 2005 for the rules repository. This was working just fine for over a year now. After restarting the server, I was not able to see any of the rules. When I logged into Guvnor It said that repository appears to be new and asked if I wanted to install the samples. We restored the database to a previous dump and I was able to see the rules if I went in through categories. However, I can't see the rules under the Package view. I also can't build a package nor export the rules as XML. Nor can I search for rules from the Find tab. I have an XML export from a few days ago that looks good but we would loose the history of rule changes. Any ideas on how to get our Guvnor working? thanks, -tk Tharakesh Siddalingaiah Solution Architect GTO GIS Core Banking - PWM IT US Deutsche Bank AG Tel: +1 (410) 895 5275 Mob: +1 (410) 905 2169 tharakesh.siddalingaiah(a)db.com --- This communication may contain confidential and/or privileged information.
