Re: [rules-users] Regarding Drools Rules Engine
Some remarks, see below. 2009/12/2 Anupindi RaviShankar iamrav...@gmail.com: Hi All, We are evaluating Drools rules engine for one of the clients. The client has given some parameters based on which evaluation needs to be done. We were not able to get this information from Drools site. So need your help in getting this information. • Number of transactions Drools Engine can support. Can it support around 1-1.5 million transactions. The term transaction is typically used for a unit of work performed within a (database) system. If this is meant, then the question askes is usually how many per second. • How can we introduce enforcement levels, overriding authority etc.? I'Ve been reading a lot about rule based systems, but enforcement level is absolutely new to me. (Google comes up with some strange, unrelated quotes.) Also, overriding authority seems to be more related to the law than anthing else. • How can the controlling class get to know which rule was fired and which was overridden ? The concept of overriding a rule is also unusual with respect to rules. There is nothing I can relate to this verb's meaning. -W • Does the rule engine support the tracking of different rule types? Can you please provide your updates on the same.

My approach is to extract the zip and put it into my dropins directory within eclipse: eclipse dropins drools-5.1.0.SNAPSHOT-eclipse-all I would make sure you get rid of all the artefacts in your current eclipse features/plugins dirs first.

[rules-users] Drools Design Patterns
I've been using Drools for about a year now, but still consider myself a newbie, although I'm starting to get a better idea of how to implement solutions, for the experts this is probably second nature. Whilst the Drools doco is very good, and the blog/mailing lists are a great source of info, and there are now some very good books on Drools, there is a hugh amount of functionality emerging in the Drools project, it's almost becoming a full time activity just to keep up. I wonder if the time is coming to start collecting real experiences into a form that makes it easier for new users to work out how to attack their problem. I hate to re-invent the wheel and if this exists in some form elsewhere, I'd like to know. If not, then it might be good to capture this knowledge in some way. I'm interested in some views from the user community on what they would like to see. Maybe the way to go is add some pages to the JBoss Drools wiki and evolve it from there, and provide a way for the drools user community to contribute to the overall success of Drools, rather than just ask questions. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Can we use 'from' CE in Decision Tables ?
Hi Gurvinder. Not sure where new lines have gone from your email - it makes it very hard to read! I've also been working on a project which uses decision tables and I couldn't find any way to use from statements either. I'm hoping to get some time within the project to work on the drools decision table code to add some improvements, providing support for the from clause is one of these however I'm not sure whether I will get time or not. However I think you may be able to restructure your code so that you don't need the from cause however I've not fully tested it. The code relies on their existing a constructor which takes the promotion code and the equals is defined that P1.equals(P2) when P1.code.equals(P2.code). If you wanted to match that a promotion of a particular name exists then I think you can use the rule Rule existsPromotion when Line(promos contains (new Promotion(HOTBUY))) then ... However the expression language doesn't support not contains which means you have to full back to use java: rule contains d when line : Line(eval(!line.getPromos().contains(new Promotion(HOTBUY then ... end If you prefer you could also define a method on Line containsPromotionWithCode(code) which would let you choose how to do the match.

Thomas, Thanks the response. I'm not sure how the newlines disappeared from my post either. I do know I'd put them all there neatly formatted. I'll try out solution you provided and let you know how it goes. I guess I'll have to resort to quite a few evals in my decision tables, given that 'from' does not work in there. Don't like it, but if it works, at least I'll be able to acheive my project's objects. Thanks again for the solution. I'll let you know how it works out.

[rules-users] CEP + prevent consequences from triggering multiple times?
Hi, I'm trying to write a rule in drools, which triggers once some condition is active for a specified time interval. For example, if a vehicle is over a speed limit (100 mph) for 30 seconds, I want to trigger an action. However, once this rule has fired, I don't want it to fire again until the vehicle has dropped below the speed limit (and gone over the limit again). The only way I've managed to model this is by defining two rules; one for determining when the vehicle is speeding and one for determining when it is not speeding and using a global object to track the state of the vehicle (see rules below). rule OverSpeedLimit no-loop true when $minSpeed : Double() from accumulate( $speedingEvent : SpeedingEvent ($speed : speed) over window:time( 30s ) from entry-point SpeedingStream, min($speed) ); eval ($minSpeed 100.0 !state.speeding) then state.speeding = true end rule !OverSpeedLimit no-loop true when $speedingEvent : SpeedingEvent() from entry-point SpeedingStream eval ($speedingEvent.speed = 100.0) then state.speeding = false end My questions is: Is there a better way to model the above behaviour, preferably as a single rule? The reason I ask is because I believe it would be too complicated for my users to define rules like this. Ideally, I would like to be able to create a DSL such as: when Speed is above X for Y seconds then ... Any help greatly appreciated.

Re: [rules-users] CEP + prevent consequences from triggering multiple times?
Have you tried truth maintenance? (i.e. insertLogical) rule OverSpeedLimit no-loop true when not SpeedingIndicator(); $minSpeed : Double(doubleValue 100) from accumulate( $speedingEvent : SpeedingEvent ($speed : speed) over window:time( 30s ) from entry-point SpeedingStream, min($speed) ); then insertLogical(new SpeedingIndicator()); end Though I'm not sure this will work, because inserting the SpeedingIndicator negates the first condition, probably causing the SpeedingIndicator to be retracted automatically. :) But it's worth a try just to see if no-loop would override that somehow. Apart from that, note that you can test the results of an accumulate in the returned value. (The Double(doubleValue 100) part.) YOu don't need the eval. Also, where is the state object coming from? If it's a global, it's not a good idea to use them in the conditions of your rules. Changes to them are not tracked by the rete. --- On Thu, 12/3/09, reverselogic reverselo...@gmail.com wrote: From: reverselogic reverselo...@gmail.com Subject: [rules-users] CEP + prevent consequences from triggering multiple times?

The problem mentioned by Richard is fixed in trunk. Regarding Guvnor

Regarding your comment on the documentation, it is documented here:

use the code from previous post to load the pkg...
it works fine..
now, goto guvnor advanced view and change the Configuration from:

Re: [rules-users] Trivial rule with condition in RHS won't compile, help please
Ok, I found http://n3.nabble.com/Strange-MVEL-error-td62055.html#a62055 which indicates that expressions are disabled in mvel RHS. I understand good intentions, but I **need** this expression for this particular situation. Anybody know some what to turn this back on? Also, when I try wrap the RHS in a function, that also fails. I'm guessing because I declare dialect mvel for the entire file.

I would assume that you're trying to test out rule writing and see
what works and what doesn't. I don't believe you can use if
statements in the RHS.
Normally, anytime you want to use if statements inside the RHS, it's
a sure sign that you should move it to the LHS and create separate
rules.
You can actually make your rule even simpler:
rule test
dialect mvel
when
//empty LHS automatically implies true
then
System.out.pritln(***)

You can use them in the RHS, but just with java dialect. The RHS code should
then be passed through with no modification.
And there are occasional reasons why you would want to test conditions in the
RHS (optimization, mostly) but should be avoided most of the time.

Re: [rules-users] CEP + prevent consequences from triggering multiple times?
Hi Greg, Thanks for the response. Unfortunately your example doesn't appear to work, the SpeedIndicator doesn't get retracted, causing the consequence to only ever trigger once. However, I could add another rule to remove the SpeedingIndicator - meaning I no longer have to use the nasty global state object from my example. Any other suggestions greatly appreciated.

Well, technically you choose a different dialect because you want different functionality, so consistency isn't a requirement. I do agree that the difference is not intuitive.

Hi Thomas, Just wanted to let you know that the eval soution finally worked. I create a 'containsCode' method on my Line bean and then used that to see if the Line contained a given code.

The code relies on their existing a constructor which takes the promotion code and the equals is defined that P1.equals(P2) when P1.code.equals(P2.code). If you wanted to match that a promotion of a particular name exists then I think you can use the rule Rule existsPromotion when Line(promos contains (new Promotion(HOTBUY))) then ...

However, when I try to define it in a decision table so that the 'code' can be feed from a spreadsheet, I use the following values in the rules cells : RuleTable HOTBUYS CONDITION ACTION l : Line not ( Promotion ( code == $param ) from l.promos ) System.out.println($param added); PROMOTION PROMOTION HOTBUY BESTBUY I'm getting the following parser errors [10,17]: [ERR 101] Line 10:17 no viable alternative at input 'Promotion' in rule _11 in pattern Line [10,29]: [ERR 101] Line 10:29 no viable alternative at input 'code' in rule _11 [10,63]: [ERR 102] Line 10:63 mismatched input ')' expecting 'then' in rule _11 java.lang.IllegalArgumentException: Could not parse knowledge. at com.sample.DecisionTableTest.readKnowledgeBase(DecisionTableTest.java:85) at com.sample.DecisionTableTest.main(DecisionTableTest.java:28) Also in Eclipse IDE, I get the following error : Unknown error while parsing. This is a bug. Please contact the Development team. NewPromotions.xls Is it possible to use 'from' conditional element in decision tables ? If so, what am I doing wrong.

[rules-users] CEP fusion
Hello, I have this test rule that basically fires if a followup reading is not received with the appropriate value within some time. According to the fusion docs, simply using: *not*( FollowUpReading(value == $val, *this* before[0s,5s] $reading ) ) should wait 5 seconds before firing, however this does not work unless I explicitly also set: *duration*( 5s ) and if I do that, it seems to wait the 5 seconds, however it always follows what I put in the duration value and seems to compeltely ignore the time tolerances I use here.: $reading : DatarReading($val: value) *not*( FollowUpReading(value == $val, *this* before[0s,5s] $reading ) ) And if I have different values, it will fire the rule after 2 seconds and ignore the 5s in the sample below. Any ideas? * rule* my rule *duration*( 2s ) *when * $reading : DatarReading($val: value) *not*( FollowUpReading(value == $val, *this* before[0s,5s] $reading ) ) *then* System.err.println(did not receive follow up - reading value: + $val); * end * ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Need help related to collection of data accessing in rule file.
I have the same problem as I'm trying to create a decision table via excel where the fact is a root object A where A has a collection B, and B has a collection C. My rules are based out of the instance A, loop for each object in B, and within that, loop each object in C. Not sure how I can write an expression for the same. From the examples, I see that one can access a particular element in A by $a.listname[1] but in my case, I need to access all elements in the loop. Any suggestions? prasad raju sagi wrote: Hi , I am trying to create rule on a fact , which contains arraylist of collection and the object in the collection internally contains an arraylist of another collection of objects.

Re: [rules-users] Drools Design Patterns
Thanks Mark, Wolfgang, I think this is a worthwhile area, although difficult. My hope was that ordinary users might have a view of what they want to see, not necessarily formal patterns, but just ways of doing common problems. Hopefully we get some more responses from the community, but anyway I'll see what I can do from a naive user perspective.

Whilst the Drools doco is very good, and the blog/mailing lists are a great source of info, and there are now some very good books on Drools, there is a hugh amount of functionality emerging in the Drools project, it's almost becoming a full time activity just to keep up. I wonder if the time is coming to start collecting real experiences into a form that makes it easier for new users to work out how to attack their problem. I hate to re-invent the wheel and if this exists in some form elsewhere, I'd like to know. If not, then it might be good to capture this knowledge in some way. I'm interested in some views from the user community on what they would like to see. Maybe the way to go is add some pages to the JBoss Drools wiki and evolve it from there, and provide a way for the drools user community to contribute to the overall success of Drools, rather than just ask questions. -- ___ rules-users mailing listrules-us...@lists.jboss.orghttps://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- ___ rules-users mailing listrules-us...@lists.jboss.orghttps://lists.jboss.org/mailman/listinfo/rules-users ___ 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
