Hi All

I am new to drools and i am trying to install Guvnor in Jboss5.0.1 GA  .I got the below error
DEPLOYMENTS IN ERROR:
  Deployment "persistence.unit:unitName=#ACL" is in error due to the following reason(s): java.lang.RuntimeException: Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a non-jta-data-source for a RESOURCE_LOCAL enabled persistence context named: ACL


I removed the jars mentioned as per the link below but still the error remains the same.
https://jira.jboss.org/jira/browse/JBRULES-2034

Can someone plz point me to the permanent solution to this problem.
Same error is there if I try to deploy Guvnow war file in Weblogic.Is Gunor deployable on Weblogic.

Thanks,

This is exactly the approach I used in JBRULES-2225, because not just  
was the locking broken, it also produced measurable contention in our  
application.
The fixed version behaved considerably better.

Have you also defined the "fact" process variable? You can do this by
clicking on the background of you process in the editor and updating the
variables parameter, or in the header in xml:

<header>
 <variables>
   <variable name="fact" >
     <type name="org.drools.process.core.datatype.impl.type.ObjectDataType"
           className="org.drools.ProvFact" />
   </variable>
 </variables>
</header>

Otherwise the process won't know where to find the "fact" variable
(because you could have multiple, nested variable scopes if you start
using composite nodes).

Mike and Wolfgang, things are clearer now, I will definitely try to your suggestions.

Thanks for the help,

Hello Joel,

nothing on the LHS (between when and then) matters when a rule fires; so eval() and all other CEs are evaluated when facts are inserted.

So, trying to get rid of the eval's would be worthwhile.

The second thing (and I agree with Michael) is that you shoudl get rid of collect, which causes the delay during insertion. I'd also use a Collector fact with attributes for deal, a booking rule and a count.

rule addCollector
when
   $deal: MarketDealModel()
  not (Collector( deal == $deal )
then
  insert( new Collector( ?deal ) );
end

When there is a matching Collector and a BTExecutionBookingRuleModel matches the deal:
then
modify the collector by incrementing the count and storing the matched booking rule

At a lower salience, add 2 rules matching a collector with count == 1 and count != 1 with obvious consequences. (The second one could switch to the next level activation group.)

HTH
Wolfgang

Hi Mike,



Quick reply, thanks !



I think I can't use ? exists ? because I want one and only one booking rule of a specific level (LEVEL_1, LEVEL_2, ...) matching a deal, that's why the bookingRuleModels list collected should only contain 1 booking rule. This explain why in the RHS I'm getting the first booking rule (bookingRuleModels.get(0)).

If there is more than one booking rule (or none), I switch to the second Drools rule which tries to find a unique LEVEL_2 booking rule, then same thing if none or too many, switch to LEVEL_3 booking rule ...



Hope you get the idea.



The matchXXX function compare the XXX criterion of a booking rule (ex Trader) with the corresponding Deal attribute (ex Trader).

Here's the implementation for comparing trader criterion, note that if a booking rule does not specify a criterion it is considered as matched.



 private static boolean matchCriterion(NorthIdEntity<?> ruleCriterionModel, NorthIdEntity<?> model) {

   if (ruleCriterionModel == null) {

     // no criterion => matching ok

     return true;

   }

   return ruleCriterionModel.equals(model);

 }



I have read that eval is not performant but I thought it was only when executing rules not at facts insertion phase.

Is this coorect or is eval impacting negatively facts insertion ?



Another idea comes to my mind : can I use a stateless session since once a deal is classified/booked we don't want to process it again ?



To finish I forgot to give informations on my environment, it may be useful :

- Drools version 5.01

- java 6

- launching my server with following memory options : -Xms256m -Xmx1024m





Thanks again for your thought,



Joel

Hi,



As an aside, you shouldn't need to use a rule flow as the rules themselves determine which RHS is activated. Could you consider using "exists" instead of the "ArrayList( size == 1) from collect..." - it looks like you're not too bothered which Booking Rule matches as (I believe) you have no way to determine which is at index(0). Also, what do your "matchXXX" functions do? Could you investigate removing the "evals"?



I don't have any knowledge of your domain - we're all newbies at some time or other.



With kind regards,



Mike

Subject: [rules-users] Memory error when inserting facts in stateful session

Hello,

To be short I'm facing some performance/memory problems with Drools which leads to the error : java.lang.OutOfMemoryError: Java heap space.

That was for the short story, let me now give you more details.

First, I'm a Drools newbie so I certainly have made some "bad" choice.

I'm using Drools 5.01 to classify automatically the deals made by the traders of my company (this is the functionnal problem I want to solve with Drools).

I have written 4 rules, a rule-flow and start the deals classifying process with a stateful session.

I have successfully (unit) tested different scenarios, so everything is ok on a functionnal point of view.

Problems arise when I started to insert more deals in the session, which leads to an OutOfMemoryError before the call to ksession.fireAllRules. logs are below (after the drools rule).

Number of facts I have tried to insert in my statefull session :

-         222 booking rule (POJO expressing classification criteria)

-         750 product index

-         750 deals

What drools does here is to find the correct booking rule to apply for each deal (we need some product index for that).

Can you tell me if those numbers seems unrealistic ?

What can I do to avoid the memory errors ?

To be complete, I show you the drools rules :

rule "Find and apply level 1 booking rule"

     lock-on-active true

     ruleflow-group "Level 1 booking rule group"

     when

           dealModel : MarketDealModel( $dealPortfolio : portfolio, $dealTrader : trader, $dealProduct : product)

           // retrieve the ProductRelatedIndexes corresponding to the deal product (only one by product)

           productRelatedIndexes : ProductRelatedIndexes( product.internalCode == $dealProduct.internalCode, $dealProductIndexes : relatedIndexes)

           // try to find one and only one level 1 matching rule (level 1 <=> all matching criteria are defined).

           bookingRuleModels : ArrayList( size == 1 ) from collect (

                 BTExecutionBookingRuleModel(

                       priority == BTExecutionBookingRuleModel.LEVEL_1

                       && eval(matchTraderCriterion(traderCriterion, $dealTrader))

                       && eval(matchPortfolioCriterion(portfolioCriterion, $dealPortfolio))

                       && eval(matchIndexCriterion(listedIndexCriterion, $dealProductIndexes))

                       && eval(matchProductTypeCriterion(productTypeStringCriterion, $dealProduct))

                 )

           )

     then

           Logger log = LoggerFactory.getLogger("BOOKING RULE ENGINE LOGGER");

           // get the unique collected bookingRuleModel.

           BTExecutionBookingRuleModel effectiveBookingRuleModel = (BTExecutionBookingRuleModel) bookingRuleModels.get(0);

           // log.info<http://log.info>("Found matching level 1 booking rule --> " + effectiveBookingRuleModel);

           effectiveBookingRuleModel.applyRuleOnDeal(dealModel);

           retract( dealModel );  // only needed in use of stateful session to avoid processing this deal again.

end

I don't put the 3 others, they are basically the same except the priority == BTExecutionBookingRuleModel.LEVEL_1 which is done against LEVEL_2, LEVEL_3 and LEVEL_4 rule.

Each rule is in his own ruleflow-group, it is very basic, if first drools rule is not active then we try the second (with compares priority to BTExecutionBookingRuleModel.LEVEL_2).

I also put some logs showing that inserting deals fact takes longer and longer :

- the 222 booking rule are inserted in 16ms

- the 750 booking rule are inserted in 46ms

- the 750 facts are inserted at a pace of 5 by second, then it starts to deteriorate to several seconds for one insert to finish with the OutOfMemoryError.
