Re: [rules-users] Using global variable in DRL file
How do the record counts relate to files? 1800,12k and
9.5k =:= ABPolicyTransactions, ABPolicy, ABAgent?
Are these two rules all there is?
The second one has
$csvPolicy : CSVBeanPolicy()
//$csvAgent : CSVBeanAgent() --- assume this is not commented out
Now if you do insert CSVBeanAgents, this will create (using the
*assumed* record counts) that you'll get 12,000*9,500 = 114.000,000
activations! This is the reason for your heap problem.
The RHS of this rule has an if, comparing agent ids from both facts.
(If statements on the RHS is an anti-pattern, with rare exceptions!)
Conditions belong into the LHS!
rule accumulate policy APEs into agent APE
when
$csvAgent : CSVBeanAgent( $agno: agentNo, $agAPE: agentAPE )
$csvPolicy : CSVBeanPolicy( agentNo == $agno, $polAPE: policyAPE )
then
modify( $csvAgent ){
setAgentAPE( $agAPE + $polAPE )
}
end
Now, inserting all facts will still create some activations, but only
12,000, the number of ABPolicy records.
Firing the rules after each insertion of an agent will not let more
than one activation accumulate - you can't have less that that :)

Hi Laune and thanks for replying
Actually it was not just 50,000, it was 1,00,000 records in single CSV that
we solved the Heap space problem by your help and we have developed that
product and successfuly integrated in Liferay Portal... :)
Now in this case, we have to read* three CSV files* having *1800,12k and
9.5k* records. Now our concern is that if it was running fine for 100
thousand records then why it is creating problem data which is much lesser
than 100 thousand.
Actually we are thinking in the direction like, it might creating problem
because increased number of columns in each of three CSV files that we are
using compare to that 100 thousand records in which we had 8 columns but
only one file.
Another concern is ,there may be possibility that as we are generating
objects from 3 CSV one after another then firing rules might creating
problem...?? Please help us in finding out what is the reason for this

Re: [rules-users] Apply role to whole class hierarchy
Thanks for your help, Edson! We are using drools 5.4.0.Final via maven. Maybe I am missing something, so here's a quick overview of what we do. We have a model class ButtonEvent which is derived like this: ButtonEvent - ZonedEvent - VSCPEvent Then there's a rulebase with something like this: import test.vscp.VSCPEvent; import test.vscp.information.ButtonEvent; declare VSCPEvent @role( event ) @timestamp( timestamp ) @expires( 1h ) end declare ButtonEvent @role( event ) @timestamp( timestamp ) @expires( 1h ) end rule Button long pressed when b : ButtonEvent( action == Action.PRESSED ) not( ButtonEvent( action == Action.RELEASED, this after[0s,1s] b ) ) then ... end What I would have expected is that the second 'declare' statement to be unnecessary.

[rules-users] [Planner][DRL] Changable problem facts?
Hello! I am working on task scheduling system. My system works fine, but I want to make it faster. For my current problem we can assume that my domain consists of: * Worker (int id, ListTimePeriod workingHours) * TaskAssignment (int id, ListTimePeriod possibleExecutionTime, Duration leadTime, Worker worker) I am trying to assing each Task Assignment to 1 worker. It's obvious. All I need to do is to make my rules computing faster. For example I have a rule: rule ASSIGN_OUT_OF_WORKING_TIME when $w : Worker($id : id != 0, $wh : workingHours) $ta : TaskAssignment(worker != null, worker.id == $id) not TimePeriod( isBetweenInclusive($ta.getTimeSlot()), isBetweenInclusive($ta.getEndTimeSlot()) ) from $wh then insertLogical(new IntConstraintOccurrence(ASSIGN_OUT_OF_WORKING_TIME, ConstraintType.NEGATIVE_HARD, 100, $w )); end This rule checks if every TaskAssignment assigned to a Worker lies in the worker's working hours. The problem is that score calculator is trying to pair given Worker with every TaskAssignment. So I have to make set of TaskAssignment as small as possible. I can acquire that by storing in a Worker any kind of Set including all assigned TaskAssignments. After this my domain should looks like this: * Worker (int id, ListTimePeriod workingHours, SetTaskAssignment cashedTaskAssignments) * TaskAssignment (int id, ListTimePeriod possibleExecutionTime, Duration leadTime, Worker worker) and my rule: rule ASSIGN_OUT_OF_WORKING_TIME when $w : Worker($id : id != 0, $wh : workingHours, *$cta : cachedTaskAssignments*) $ta : TaskAssignment() *from $cta* not TimePeriod( isBetweenInclusive($ta.getTimeSlot()), isBetweenInclusive($ta.getEndTimeSlot()) ) from $wh then insertLogical(new IntConstraintOccurrence(ASSIGN_OUT_OF_WORKING_TIME, ConstraintType.NEGATIVE_HARD, ASSIGN_OUT_OF_WORKING_TIME, $w )); end My cloneSolution() method is cloning everything right (deep clone of every TaskAssignment and Worker). I've checked it via many tests. Anyways I'm getting: *Score corruption: the workingScore (-1800hard/0soft) is not the uncorruptedScore (-1904hard/0soft):* or similar error. To sum up: * my system works fine without any changes in Worker class * I want to make it faster by caching assigned TaskAssignments in a Worker objects * I'm getting 'Score corruption' error Is my idea possible to play out? -- View this message in context: http://drools.46999.n3.nabble.com/Planner-DRL-Changable-problem-facts-tp4018944.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] Using global variable in DRL file
Ah, yes - there are multiple updates of an Agent from several
different policies.
Now, it depend: Is the computed sum of the APEs in the Agent used in
any other rule? If not, the solution is simple. Do not use
modify/update; simply accumulate the values, using the setter, and in
this case you can even omit the no-loop.
rule accumulate policy APEs into agent APE
when
$csvAgent : CSVBeanAgent( $agno: agentNo, $agAPE: agentAPE )
$csvPolicy : CSVBeanPolicy( agentNo == $agno, $polAPE: policyAPE )
then
$csvAgent.setAgentAPE( $agAPE + $polAPE );
end
If you do need the updated CSVBeanAgent.agentAPE, it's a little more
complicated and I should test the solution before I post it. - Or if
you want to try untested: you'll need an accumulate, like this:
rule accumulate policy APEs into agent APE
no-loop true
when
$csvAgent : CSVBeanAgent( $agno: agentNo, $agAPE: agentAPE )
accumulate( CSVBeanPolicy( agentNo == $agno, $polAPE: policyAPE );
$sum: sum( $polAPE ) )
then
modify( $csvAgent ){ setAgentAPE( $sum ) }
end
Note that this assumes that the old value in agentAPE is 0 or can be
overwritten; otherwise you might need to add the old value to the
$sum.

Sorry, I think I missed this, all you need is a no-loop in the rule :)

Hi Laune !
I applied your suggested changes but the loop is running infinitely and
same
policyAPE is used to generated cumulated value I mean for 1 agent it is
expected that all the policy APEs should sum up to generate Agent APE
but
same policy APE getting summed up infinitely.plz find attached of my
consolewe printing in console in following order --- *
System.out.println($agAPE+ZZeeesshhaaannn+$polAPE);*
Also find my updated RuleMain and Sample.DRL...
thanks very much again !

Re: [rules-users] Rule Templates
The information that would help me is (using Eclipse or JBDS) can one edit, It depends if you mean edit the templates or edit the data that you use to populate it. You can create a rule template in any text editor you like and, AFAIK, it can have any extension you prefer. Convert it to an inputstream and use it in the code as is documented. Regarding the data source, you have multiple options to collect the data. Editing this data depends a bit on the type you are using. I typically convert xml objects to java objects and use (and, sometimes, abuse) them to fill the template and generate rules. compile to drl Compile to drl is done using the code as documented. String drl = converter.compile( objs, templateStream ); You can do with the String whatever you like. use it to feed a knowledgebuilder directly, or write it to a file. and test the rule templates Again. This depends on what you mean. If test the rule templates means: check whether it generates a correct drl, than there are 2 things you can do. 1) Manually check that the rules are as you expect them to be. 2) Verify that the drl compiles in a knowledgebuilder. If test means, check whether my generated rules can construct a correct decision, then you wikk have to set up a service/a method/ a unit test in which you use the rules to create a knowledge base and which takes input data to generate a certain output. If you want, you can use guvnor to create test scenarios or implement a testing tool by your own. Regards, Frank mclovis wrote Frank, Thank you for your quick reply. I had previously read your suggested documentation and understand the basics of rule templates. The information that would help me is (using Eclipse or JBDS) can one edit, compile to drl and test the rule templates. The information in the article does not reflect these things and furthermore has a lists of file types for Drools that is not in current versions of IDEs (example: rules resource). If you have knowledge of the mechanics of these things (using even Ant or Maven to compile), it would be much appreciated.
