Do you use a stateful session?
Are your measurements before and after you've inserted facts into
working memory?
Would be helpful to the group to post your use-case source?
Thanks,

We used two approaches to double check results.
At first we used an approach similiar to what you haved described.
Please note that (depneding on platfom) freeMemory is not byte-
exact). Wo you won't see little changes.
Also, if you were using stateless sessions the result you have seen

Hi everyone,
isn'it there a way to find when a rule isn't more active.
For example if i have this rule:
rule light 2 on
dialect java
when
Light (name==0/0/2, actualvalue==1);
then
System.out.println(luce 2 on);
end
when someone turn on the light 2 i discover that the rule is fired using an

Hi all,
Our object deals with the clinical domain. We have a class LabEvent that
represents a visit in the laboratory. Each event is associated (using the
laboratoryResult association) with one or more LabResult objects (children),
each represents the results of a particular test.
in the rule
There is a mechanism called truth maintenance ensuring for example
A - B
B - C
that C becomes false when it's premise (B) becomes false as well.
What it basically does it track the LHS side of the rule and undoes
asserted facts when there are no more facts to support it (activate

Hi Thomas and all,
Drools delegates most of the complex expression evaluation to MVEL and it
seems that it currently does not support variables as indexes in the
map/collection simplified syntax. So, it will not work for now.
The good news is that we work very close with MVEL's author
I've thought about some callback mechanism that is executed when a rule
is no longer true, the problem I have is which variable changed to make
the rule no longer true and how do I expose the bound variables to the
user, especially if the rule is no longer true due to a retraction, and
What about:
Number( intValue 1 ) from accumulate(
LabEvent( eval( dateWithinLastMonths(effectiveTime,1)), results :
laboratoryResult ) and
LabResult( value 1.8 ) from results,
count( 1 ) )
Accumulate supports multiple patterns and has the count() function.
thanks a lot

The same interface you are using (AgendaEventListener) has 2 methods for
activations created and canceled:
void activationCreated(ActivationCreatedEvent event,
WorkingMemory workingMemory);
void activationCancelled(ActivationCancelledEvent event,
For Drools 4.0.x we eventually run profiling tools to make sure we got

any leak in 4.0.7.
It is very important though to make sure that if you are using stateful
sessions, you call dispose() on the session after

If you have each character in a different attribute, you can use in and
not in to list the valid/invalid characters:
a : Abbreviation( pos1 == 'A', pos2 in ('-','D','H'), pos3 == '-',
pos4 in ('O', 'R', 'U', 'L') )
a : Abbreviation( pos1 == 'A', pos2 not in ('-','D','H'), pos3 !=

Hello,
I have a HashmapString, Double hm as Input and want to execute the rule
for each key respectively value.
when
hm: HashMap()
value: Number() from hm.values()
key: String() from hm.keySet()
then ...
But unfortunately it doesn't work like this. Any ideas?

As an update, MVEL author fixed this and will do an MVEL release soon.
When he does, we will test here and let you know, but you should be able to
simply replace MVEL jar and it will work.

Hi Thomas and all,
Drools
Yes i know this. I've tried to use activationCancelled method to
discover when a rule isn't more true but it doesn't work. The code was
public static class FiredRulesListener extends
DefaultAgendaEventListener static class FiredRulesListener extends
DefaultAgendaEventListener
