[rules-users] OutOfMemoryError using 6.0.1

[john poole]

I've converted some NurseRostering rules, which worked in Drools 5.50, to
OptaPlanner 6.0.1. While it works far better for the time it runs, it uses
up whatever memory I can give it (9GB) and then eventually crashes the GUI.

with:
Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: GC
overhead limit exceeded 

Is there a way to limit how much memory OptaPlanner uses? Or is it likely
that I'm just adding fact to the WorkingMemory in a way that wasn't a
problem in 5.5 but is a problem in 6.0?

[rules-users] How to initialze a query parameter or set an empty list

[ismaximum]

Hi all

So I have this query:

query listPrimaryBenefits(List primaries)
RuleInsuranceSubtype($subtypeId := id, riderFlag != "Y")  and 
primaries := List() from collect (InsuranceCover(benefitTypeId ==
$subtypeId, topup == Boolean.FALSE))
end


outside the query and within my rule I have this checking:

rule "Test rule"
when
  listPrimaryBenefits($primaries;)
  eval($priamries == null || primaries.isEmpty())
then 
  assert 


Now, if there is a RuleInsuranceSubtype in WM with given condition,
everuthing is fine and $primaries is empty and being checked in eval
statement BUT if there is no  RuleInsuranceSubtype in WM with riderFlag as N
(which is a valid scenario) then the whole query returns false and as the
result in the rule, my eval statement won't even get executed and its 'when'
returns false.

How can I prevent this? I tried to put OR but don't know how to set
$primaries to an empty or null value. 

Does anybody know how to do this or have a better solution?

Thanks

Re: [rules-users] kieContainer version as LATEST for Drools 6

[Mark Proctor]

We want it to be quick. I hope 4 to  weeks. We’ll do one beta, one CR and then 
final.

Also it might be called 7.0. We are being asked to differentiate community 
versions, with our product version - by increasing the community version number.

[rules-users] java.lang.NullPointerException in simple example

[ahgiovanini]

Hi guys! 

I'm new in the world of jboss and drools and I'm making some simple examples
that existing on
https://github.com/droolsjbpm/drools/tree/master/drools-examples-api

Now, I'm studing the CashFlow example and in my project when I run it, I
receive a error message saying: 
Exception in thread "main" java.lang.NullPointerException

[rules-users] Drools with Microsoft SQL Server

[Hong Ju]

Hi,

Has anyone had an experience to configure Drools to use Microsoft SQL server? 
We have been using H2, but we want to switch to SQL.  This is my persistence 
unit:

  org.hibernate.ejb.HibernatePersistence
  jdbc/processInstanceDS
org.drools.persistence.info.SessionInfo
org.jbpm.persistence.processinstance.ProcessInstanceInfo
  org.drools.persistence.info.WorkItemInfo
  org.steward.care.fact.Account
  org.steward.care.fact.ObservationGroup
  org.steward.care.fact.ObservationParent
  org.steward.care.fact.Observation
  org.steward.care.fact.ClinicalRuleMatch
  org.steward.care.fact.Comorbidity
  org.steward.care.fact.OutboundNotice
  org.steward.care.fact.Medication
  org.steward.care.fact.data.CodedElement
  org.steward.care.fact.data.StructuredValue
  org.steward.care.fact.data.TriggerMatch
  
 
 
 
 
 
 
 
  
   

This is how I configure a data pooling:

PoolingDataSource pds = new PoolingDataSource();

  // The name must match what's in the persistence.xml!
  pds.setUniqueName("jdbc/processInstanceDS");

  //
  
pds.setClassName("com.microsoft.sqlserver.jdbc.SQLServerXADataSource");

  // doesn't really matter
  pds.setMaxPoolSize(3);

  pds.getDriverProperties().put("user", "myuser");
  pds.getDriverProperties().put("password", "mypassword");



  pds.getDriverProperties().put("serverName", "localhost");
   pds.getDriverProperties().put("databaseName", "CAREDatabase");

  pds.getDriverProperties().put("URL", 
"jdbc:sqlserver://localhost;databaseName=CAREDatabase;IntegratedSecurity=true");

   // pds.getDriverProperties().put("selectMethod", "cursor");


  pds.init();


But I get this error:

Yes, it is, and you are in good company. - A thorough study of the
temporal operators or reading Hawking's A Short History of Time helps,
either one ;-)

The word is "illuminative" rather than "interesting". Take this one:

$e1: Event($location: properties["location"] && ...)
not Event(, this after $e1)

The $e1 Event is here, Time is Now. It's most certainly true that
nothing is here after Now! - And the next one:

$e1: Event($location: properties["location"] && ...)
not Event(, this after[0, 1m] $e1)

Again, Event $e1 is here, Time is Now, and nothing is here after Now.
The operator does not instruct the Engine to wait!

Cheers
Wolfgang

[rules-users] 5.6.0.cr1 Guvnor Release

[gboro54]

Is there a built Guvnor artifact for expert 5.6.0.cr1? Using the 5.5.0
version of Guvnor against the 5.6.1 runtime does not work(as I would
expected). This is only a temporary until we get the knew kie-workbench up
and running with Drools 6.

Re: [rules-users] Help with event not found over window query

[daveor]

Thanks for your email below. I needed to refactor my code somewhat to get this 
technique to work but it solved the problem that I had. 

I was previously using fireAllRules() but I refactored the code to use 
fireUntilHalt() instead, which required some additional work to make a couple 
of other supporting features behave properly. I know you don't strictly need to 
do this, but it needed to be done anyway and it made sense to do it now.

I would have thought it was quite a common scenario where someone wanted to 
implement business logic such as:

- Something happens
- It is expected that something else will happen within a certain time period 
of the first thing happening
- If the second thing doesn't happen within the time period, generate an alert

I ran into trouble because my various rules (from my original email) wouldn't 
fire an alert as expected when I fed in simulated events. 

I'm curious as to why you think it's interesting that the four rules below fail 
to meet my expectation? I suppose it's the fact that I'm a drools newbie and 
the issue here is probably just my inexperience mapping business logic into 
drools rules.

Re: [rules-users] "in" syntax breaking the Rete Tree

[droolster]

Also, when I add this condition:

rule "ABC" 
when 
A ( $p : p ) 
B ( c < $p, c in (3,4), c > d  ) 
then 
System.out.println ("Hello"); 
end 

The Rete Tree looks like this: (is that correct?)

Re: [rules-users] "in" syntax breaking the Rete Tree

[droolster]

I can't give you my exact code as it is company-sensitive code. But you can
test this against any POJO with a few int and Integer fields.

I'm trying to promote Drools Expert in my organisation so I would appreciate
your help. It's not causing a problem with rule evaluation. That is working
fine. But it doesn't look good when things which should be working are not.

Re: [rules-users] "in" syntax breaking the Rete Tree

[droolster]

This even occurs in 5.6.0 - I went back to the old version thinking it maybe
the plugin for 6.0.0.Final. It's not, it's the same problem.

Both these rule definitions cause a problem in the Rete Tree viewer tab:

rule "ABC"
when
A ( $p : p )
B ( c < $p, c == 3 || c == 4  )
then
System.out.println ("Hello");
end

rule "ABC - 2nd version"
when
A ( $p : p )
B ( c < $p, c in (3, 4)  )
then
System.out.println ("Hello");
end

It causes a problem with one of the AlphaBaseVertex - it is NULL and the
Rete Tree render fails with a NULL pointer exeception. You can still see the
tree after but that node (alphbasevertex) has no properties when looking at
the property tab for it. The rules evaluate ok. But the corresponding
information is not in the Rete Tree diagram.

What do you mean by "fails"? The rule should fire in any case.

This is not enough code for a check: Java code inserting the facts,
Java code defining the facts, complete text of the rule is required,
and Drools version.

If you look at the decision table examples in the Drools documentation you'll 
see that decision tables don't fit the pattern you have posted.

But you can rules to do what you want, and you'll need one rule for each 
comparison if a distinct action is to be performed for each inequality.

[rules-users] Attribute comparison thru decision table

[bala.ganesh]

Hi,

I have a requirement to compare attributes in two objects(Object1 Vs. Object2) 
and store the values based on business rule in object 3.
Example rules:

If (Obj1.atrr1 != Obj2.atrr1)
 Then Obj3.attr1 = Obj2.atrr1

If (Obj1.atrr2 != Obj2.atrr2)
 Then Obj3.attr2 = Obj1.atrr2

If (Obj1.atrr3 - Obj2.atrr3 > 10)
 Then Obj3.attr3 = Obj1.atrr3

We are planning to use decision table for this to avoid a separate GUI 
development.
Would like to know whether writing rule for each attribute is the only solution 
or is there any simpler approach?


Thanks in advance,
-Bala

The docs say it will. But I didn't get it working.

The unit test samples are showing only updateToVersion(ReleaseId on a ).

It's created in the normal way.

X x_obj = new X();
kSession.insert(x_obj);

I am using drools 6.0.1.Final.

I do not get a stack trace from Eclipse. But the null pointer exception is
displayed on screen when I click on the Rete Tree tab.
