[rules-users] 5.6 Decision Table VLookup
Is there a way to have a decision table behave with a vloopup? Basically we have a metadata column which the user can select from a drop down. This then drives the values of the action columns. This works except that instead of the value of the vlookup I see the actual vlookup text(i.e something like VLOOKUP(F11)). Is this possible? -- View this message in context: http://drools.46999.n3.nabble.com/5-6-Decision-Table-VLookup-tp4030082.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] 5.6 Decision Table VLookup
They are different sheets. Basically we have a our tables on sheet 1 and sheet 2 is populated from an import of data from an external datasource to allow a vlookup of information(so the business user can see the data/and we can maintain it) manstis wrote Is the VLOOKUP in the same sheet?

I will work on a test case and create a defect for it. I will see if I can't get some time to take a look at this myself but will keep you informed about my status on completing this ticket manstis wrote That then is indeed a bug. Can you please raise a DROOLS JIRA and attach a unit test demonstrating the problem (preferably please submit your unit test as a Pull Request)? We're always on the look out for community contributions, so if you want to tackle a fix it would be appreciated; otherwise we'll add the JIRA to the list to look at some time.

Re: [rules-users] Decision Tables and modify
Thanks and your assumption is correct
manstis wrote
At the momemt 6.x only supports update columns (select an action and
ensure the update engine checkbox is ticked).
You can work around this, to get modify( x ) {...}, by using a BRL
Fragment
Action column and use a Free Form DRL Fragment entering the modify syntax.
I am modifying Guided Rules, Guided Templates and Guided Decision Tables
to
generate modify syntax instead of update at the moment.
It will be in 6.1.Final for sure.
Did you mean this or the XLS variety? (I'd assume modify to already be
supported as ACTIONs are free format DRL IIRC).

No luck adding ProperReactive to the classes(in the sample project). Davide Sottara wrote I think I see the problem - though I haven't been able to test it with guvnor. Property Reactivity is resolved at compile time, when the package is built. When you load the DRL, you set PropertyReactive.ALWAYS in the (local) KnowledgeBuilder, so it will consider all classes as PR.

Re: [rules-users] Drools 5.6.0.Final PKG vs DRL infinite loop
For number 2 it is a fair to claim that the beans the rules do not live in the same package. Thanks again for the assistance Davide Sottara wrote Ok, so I have to test it. There could be two possible failure points: 1) The compiler should see the annotations and create the internal data structures, tracking the fact that the classes are @PR 2) The data structures are declared in the package of the beans, which is not (necessarily) the package where the rules are defined. We have to ensure that ALL packages are downloaded from guvnor. To check #2, it should be enough to ensure that the rules and the classes live in the same package I'll get back to you later Davide On 02/26/2014 03:59 PM, gboro54 wrote: No luck adding ProperReactive to the classes(in the sample project).

when
$firm:Firm( )
then
modify($firm){addToFirmAccumulation(va,1L,false,1)}

When I compiled and ran I didn't get the infinite looping like I did before.
The method addToFirmAccumulation is annotated with @Modifies({

[rules-users] drools 5.5 property reactive issue
I am seeing a weird pattern(or at least unexpected one) when running drools
5.5 in property reactive mode. I have to rules such as:
rule Rule 1
when
$order:Order(orderType==A, orderVolume1000)
then
insert(new Charge($order,code1,-.25));
end
rule Rule 2
when
$order:Order(orderType==A)
then
insert(new Charge($order,code2,-.24));
end
rule Set best price
when
$order:Order($id:id, $setCharge:charge)
$charge:Charge(orderId=$id,$setCharge==null ||
chargeAmount$setCharge.chargeAmount)
then
modify($order){setCharge($charge)};
end
If I insert and Order of 1001 I see all 3 activations get created, Rule 2
fires first thus triggering set price rule and the activation of Rule 1 is
cancelled. If I add a @watch(charge) to the end of the rules or set up
salience Rule 1 fires.
Could someone help me understand why the firing of Rule 2 and thus the set
best price rule cause rule 1 to get cancelled without the @watch?

[rules-users] Drools 5.5 Property Reactive on Maps
So I have an object with a map like follows:
protected ConcurrentMapString, Double accumulations = new
ConcurrentHashMapString, Double();
I wrote a convince method on the class that will look up the value in the
map and add to it if it exists and
if not there will put it in the map:
@Modifies({ accumulations })
public void addToAccumulation(String code, long volume) {
if (accumulations .containsKey(code)) {
Double value = accumulations .get(code) + volume;
accumulations .put(code, value);
} else {
accumulations .putIfAbsent(code, new Double(volume));
}
}
I have a rule to listen on the change of this filed on the object(i.e
accumulations[someCode]!=null) but
when I modify the object the rule doesn't fire. I have added
@PropertyReactive to the Object and build the kbase as follows:
Properties props = new Properties();
props.setProperty(drools.dialect.java.compiler, JANINO);
KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory
.newKnowledgeBuilderConfiguration(props);
config.setOption(PropertySpecificOption.ALWAYS);
Any insight into why this may not work?

Could you expand upon why this is a poor practice? I assumed that if a part
of the pattern doesn't match the expression evaluation is terminated
laune wrote
I can anticipate the answer where OP says that there is a constraint
restricting argVolume to 0. However, I don't think that independent
constraints such as we see them in this rule are evaluated as if they
were in a single logical expression, with Java semantics.
The seductive possibility of binding to a half-baked expression (i.e.,
$ratio:(volumeAccumulations[total]/consolidatdVolume.avgVolume))
should be discarded. This value can safely be computed on the RHS
where the denominator's value being !=0 is asserted.

Re: [rules-users] Drools 5.5 divide by 0 exception
Agreed. In this case it is possible to move to the RHS...but I have to ask
what if I need to use the math as part of a constraint. Is it not safe to
assume the divisor is 0 even if I do the check? That seems like an issue as
I do have cases which this will be required

Given that you don’t seem to using the result as a constraint, then I
can’t see any benefit to it being on the LHS. So yes, It would be better

Re: [rules-users] Drools 5.5 divide by 0 exception
Another question(on error interpretation) the stack trace seems to indicate an issue with the consequence and not the condition. Should it be assumed that seeing such errors could indicate an issue on either side of the rule? -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-5-divide-by-0-exception-tp4026582p4026594.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] Drools 5.5 divide by 0 exception
$firm should be $context...To post the rule in the public sphere I had to
modify some variables(legal company issues :-) ). The same goes for the rule
name(my replacement of text is not very good).
I understand Wolfgang's point...I just made a poor assumption(something as
someone who has used drools for several years I shouldn't have done...every
once and a while I guess I get a brain fart)
Davide Sottara wrote
Am I wrong or these are not the (only) rules that are being run?
1) The exception is thrown as the consequence of a rule called
com.nasdaq.rms.nq.status.Rule_Calculate_Firm_Participation_Ratio_cfb033f33c2b404fb2bff8e1b9af0175
Rule Calculate Firm Participation Ratio, which is not shown.
2) The Rule Add baseline to context... modifies a $firm which is not
bound anywhere
in that rule..
3) Looking at the stack trace, the consequence happens in a MVEL
Constraint, which
is in an Alpha Node immediately after an ObjectTypeNode. This usually
means that
the failing constraint is the first in the pattern, which is not the
case in your
Calculate Participation Ratio.
(to Wolfgang's point: it is not mandatory, since and is commutative,
but this is what
usually happens in practice)
You also have multiple threads... is that avgVolume computed using an
accumulate
somewhere? I wonder if there are critical races.

Agreed. In this case it is possible to move to the RHS...but I have to

what if I need to use the math as part of a constraint. Is it not safe to

as
I do have cases which this will be required

Given that you don’t seem to using the result as a constraint, then I
can’t see any benefit to it being on the LHS. So yes, It would be better
on the RHS.

AcctPerformanceStatus(acctId==$Acct.id))
then
modify($AcctContext) {addAllAcctStatuses($AcctStatuses) };
end
rule Test
when
AcctContext(getAcctStatus(Test1)!=null)
then
System.out.println(Good!);
end
I would expect that after the first 2 rules fire, that my 3rd rule would
fire if the data is there successfully(which I have done in my unit test).
However the 3rd rule never fires. Any thoughts into how to accomplish this?
We are using drools 5.5 so perhaps property reactive? These rules are
creating a context/wrapper object to make decision tables easier to
write/manage for our business users.
Thanks!

Re: [rules-users] Accumulate a on event combinations
Understood. Basically EventA is a connection lost event and EventB is a connection reopened event. In some situations the connection may be try several times and in this case we want to notify the system of a pulsing connection. So the ClosedConnectionEvent happens and then if a OpenConnectionEvent happens within 5 seconds we do nothing(if it's after 5 second we tell the system and a failover would occur). With that in mind I feel this will accomplish what I am looking for...thoughts? rule Pulsing Connection when accumulate($close:ConnectionEvent(connectionEventType == ConnectionEventType.CLOSE, $closedConnectionId:connectionInformationId) and ConnectionEvent(connectionInformationId== $closedConnectionId,connectionEventType == ConnectionEventType.OPEN, this after [0s,5s] $close); $count: count($close); $count1) then //TODO: Disconnect and go to failover end laune wrote The number of *pairs *of events A, B in the last 5 seconds (according to your first post) is not what you have formulated in your rule Raise alarm. This rule (if it were possible to write in this way) appears to count EventAs, where there is a (== at least one) matching (same id) EventB in the next 5 seconds, without any limit into the past. If you are sure that after an EventA there is at most one matching EventB, it might simplify matters. Anyway, make sure to get the requirements right, otherwise it's just groping in the dark. -W On 3 October 2012 19:31, gboro54 lt; gboro54@ gt; wrote: I thought it was? Perhaps I worded it wrong.

Re: [rules-users] Accumulate a on event combinations
Thanks. I believe you are correct(my threshold is small this is just for some testing purposes.) I like the idea you have come up with. Thanks! Davide Sottara wrote What you have written counts how many times a connection to the same endpoint (I'm assuming the connectionInformationId represents the target endpoint, in some way) has been reopened shortly after being closed. I don't know how your connection protocols work, but I could see a perfectly legit use case where your client connects to your server, closes the connection, then hey I forgot something - so it opens (and closes) a new connection. If this scenario happens more than once in the lifetime of your monitoring system, the rule fires. I'm not sure that this applies to your usecase, but maybe a better way to model the problem would be something like this? (please fix the details to match your data structures) * Server( $ep : connectionEP ) * accumulate( $c : ConnectionEvent( type == CLOSE, target == $ep ) * over window:time(5m) * and $o : ConnectionEvent( type == OPEN, target == $ep, this after[0,5s] $c ), $count : count( $c ); $count // I'd increase the threshold to 2 or 3... unless you want to capture glitches in the connection too ) In a nutshell, I would scope the pairs to the context of the same endpoint (especially if you can have different connections in parallel!), and I would also frame the temporal context within a time window. Is it possible that, occasionally, your client forgets somehting and opens two (succesful) connections in a row? If this scenario occurred twice in, say, a day, the rule you proposed would still fire.

Re: [rules-users] Drools 5.4 - Can't catch Exception
I believe this is an issue with the retract in 5.4. I removed all forms of salience to see if there was a race condition caused by that. Still got the same exception. I then took it one step more and added agenda groups and set the order in such a way that the retract rules would be the last popped off the agenda stack and still the issue arises. -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-4-Can-t-catch-Exception-tp4018981p4019107.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] Drools 5.4 - Can't catch Exception
So I keep getting the exceptions below. I have surrounded the fireAllRules with a try catch throwable block to try and debug this but I never seem to be able to catch it. This only happens in the first couple 100 invocations of the fireAllRules then never happens again(sometimes it never happens at all). Is there a way to handle this exception or prevent it from happening? I am assuming that this is occurring do to an activation being evaluated after the OrderSideContext is retracted from working memory. Anyone else run into a similar issue?

Re: [rules-users] fire a rule only once (for the time being)
I don't think it would be outrageous to build a stateful session per user. The expensive part is building the knowledge base. Session creation is cheap. slyfox wrote been thinking about this a lot. I know the real solution is to use logical inserts but I'm wondering how it would work in my case. The problem is that I may have several users with similar rules. Again, its a financial app so if a user wants to know if a price breaks a certain threshold, say low for the day, ideally when that low is broken the fact should be removed. However if I do that, would other user's rules ever fire (assuming they are looking for the same criteria)? Would it be outrageous to create one session per user? Is this a lot of overhead? -- View this message in context: http://drools.46999.n3.nabble.com/fire-a-rule-only-once-for-the-time-being-tp4018887p4018982.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] MVEL optimizer error
I was able to reproduce this error locally by updating my version of java to 1.6_31(thought I had but I didn't) The stack trace doesn't give me any information really to go off of. I have around 150 rules of which a dozen will retract the object OrderSideContext. Is there a way to get a better trace to figure out which rule may be causing this? After a retract I thought all other activations on the agenda for the tuple should be cancelled. Is this a wrong assertion?

Re: [rules-users] Drools 5.4 DSLR Stack Overflow
We are not running solaris we are on Centos with a Sun JVM. However I believe the issue is the same and am working on upgrading the JVM on our boxes. Mario Fusco wrote I think this is definitively related with the version of the JVM you're using. Exactly the same problem has been already reported on a JVM running on Solaris ( https://issues.jboss.org/browse/JBRULES-3534 ) and fixed by this commit: https://github.com/droolsjbpm/drools/commit/caf0d24f53f263e06af17ffcb2f7240cc2d38431 The fix will be available with the 5.4.1, but I am pretty sure that updating your JVM (unless you are not on Solaris too) will work for you.

Re: [rules-users] Drools 5.4 DSLR Stack Overflow
Thanks for the insight. I do have several lines of comments in this format so perhaps I will try and just change them all over to // for simplification as a test of this theory.. laune wrote The Pattern comments in org.drools.lang.dsl.DefaultExpander (defined in line 63) is vulnerable when used against strings containing '/*' followed by multiple repetitions of '*' alternating with other characters before being terminated with '*/'. The pattern (?:/\\*(?:[^*]|(?:\\*+[^*/]))*\\*+/) isn't best practice, but it shouldn't cause a stack overflow. The much simpler pattern /\\*.*?\\*/ would serve the same purpose while not causing a stack overflow.

Re: [rules-users] Drools 5.4 Jitting Error
Mario, That is what i expected(just wanted to verify). Let me know if any additional information is needed... Mario Fusco wrote In Drools 5.4 we added an optimization that JITs constraints (i.e. compile them in bytecode) after they have been evaluated for a given amount of times (currently 20). Moreover it is not true that constraints' evaluations is made in threads different from the main one. Instead it is that jitting process mentioned above that is performed in a different threads, so until the optimized version of the constraint isn't ready, the main thread isn't blocked but can continue to use the non-jitted one. The error you are experiencing is generated during the optimization process and that is why you see it happens in different thread. I will try to reproduce the issue you found just now.

Thanks Mario! That seems to have resolved the issue. I look forward to your fix. Mario Fusco wrote Ok, I've been able to reproduce your issue.

Re: [rules-users] Knowledge Base and Multiple Sessions
I did run the test and your assessment is accurate. Sessions using different knowledge bases to not perform any better. For the most part each thread is running a separate rule box, however there is one set of rules which all messages must go through (millions) while the others will have a very small subset sent to them based on what the first set determined... Vincent Legendre wrote I would say no. I think that every session has its own RETE nodes filled with its own facts. May be the different RETE instances share some evaluators (or at least generated dynamic classes that represent nodes) so it could use a bit less memory than recreating the same kbase again and again (which can affect PermGenSpace on some jvm where GC is not good at purging the permgen). But the real perf hit should be due to using multiple Thread in a single jvm : if you add too much threads, gc, swap and so on can become long. To test that may be you can test with using the same kbase for all session, and test the same with creating a new kbase for each session, and then compare the perfs (ignoring objects creation of course) ... ... and post the results back here :) My own experience of usage of multi-thread with rules is for chaining multiple rule box having distinct kbase, so I never tried that. - Mail original - De: gboro54 lt;gboro54@gt; À: rules-users@.jboss Envoyé: Jeudi 10 Mai 2012 19:12:28 Objet: [rules-users] Knowledge Base and Multiple Sessions If you have multiple sessions running on different threads against the same knowledge base, is there any performance hit during evaluation? -- View this message in context: http://drools.46999.n3.nabble.com/Knowledge-Base-and-Multiple-Sessions-tp3977702.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@.jboss https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@.jboss https://lists.jboss.org/mailman/listinfo/rules-users -- View this message in context: http://drools.46999.n3.nabble.com/Knowledge-Base-and-Multiple-Sessions-tp3977702p3980427.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] modify, retract, setFocus and Salience
I will take a stab at answering this: -Modify and Retract will cause the tree to be re-evaluated for the current facts in memory. This may cause new activations or cancellations to occur. Be forewarned that a rule that modifies a fact may cause a continuous loop if the conditions for that rule are always satisfied. If you wish to not have this behavior look at no-loop -Salience: Can be useful but I have found that using a controller fact to order execution is more efficient. The problem with Salience is that it can cause your tree to become to linear thus the behavior of the rules engine is more like a bunch of if statements rather then being able to match patterns and fire. I do use salience for some rules but try not to over do it -setFocus: I don't have anything wrong with this. This allows you to segments your rules into agenda groups. I am sure someone else on here can add more. -Mike aps4u wrote will these conditions make any trouble? waiting for a reply.. -- View this message in context: http://drools.46999.n3.nabble.com/modify-retract-setFocus-and-Salience-tp3942799p3944319.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] Contains an object
Is there a way to use contains with an object? i.e obj:Object(collection contains SubObject(string=TST,int=1)) I know you could do a from but we are writing a DSL and it would be great if I could accomplish something like this above TIA! -- View this message in context: http://drools.46999.n3.nabble.com/Contains-an-object-tp3941334p3941334.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] Contains an object
I guess I could also have a method on my main object that takes parameters and just do a not null check... gboro54 wrote Is there a way to use contains with an object? i.e obj:Object(collection contains SubObject(string=TST,int=1)) I know you could do a from but we are writing a DSL and it would be great if I could accomplish something like this above TIA! -- View this message in context: http://drools.46999.n3.nabble.com/Contains-an-object-tp3941334p3941343.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
