Drools benchmarks
by tomdc
Hello,
I'm looking for some statistics on the memory usage and speed of executing
rules when using Drools.
I was wondering if anyone has lately done some benchmarking on Drools 5.X ?
The last results that I keep on stumbling on are from 2009.
If anyone can point me to some recent graphs (or data that can be turned
into a graph) concerning benchmarks on the latest Drools version?
Thanks in advance
TDC

Is Drools Scorecard used only with spreadsheet type?
by Daniel Souza
I was looking for Drools Scorecard in the sources code and I noticed that
have use just for spreadsheet at the ScorecardCompiler class.
We know that it's something new the integration with PMML and I deeply
interested in it.
Is There a way to create directly a DRL type file to work with Drools
Scorecard?
I don't know how PMML work, but I know why PMML is used. It's an interesting
project that will be a good solution.
Maybe if I understand how to compile both I can try myself some tests and if
it's possible to use rules in the traditional way to compile with PMML I
will try too.

Skill requirement not satisfied
by adc
I am running a nurse rostering instance. But the skill requirement is not
satisfied.
I have already checked that:
- For each shift, the Shift/Skills/Skill tag is set with the proper Skill
value.
- For each employee, the Employee/Skills/Skill is set with the proper Skill
value.
- For each DayOfWeekCover, the DayOfShiftCover/Cover/Shift tag is set with
the proper Shift value.
When I run the NurseRosteringPlann, assignments are made. But I see that:
- The skill requirement is not satisfied.
- The best score is reached when all the assignement are made.
Where do I fail? What should I check?

"not in" in decision table with string input errors out
by john_appleseed_79
In my decision table I have the following input data -
+----------------------+
|CONDITION |
| |
|$data not in $param |
|Header |
|("123","234","00456") |
+----------------------+
This errors out with the following error:
[40,30]: [ERR 101] Line 40:30 no viable alternative at input ''
[43,0]: [ERR 102] Line 43:0 mismatched input ''
[6,36]: [ERR 101] Line 6:36 no viable alternative at input '\' in rule
"Pricing bracket_11"
[0,0]: Parser returned a null Package
How do we make sure that the not in comparison works for strings in Decision
Table. It seems quite easy on a DRL file. If somebody can help me out on
this, I would be very thankful.

Drools scalability in home automation scenarios
by riri
Hy everyone,
I have recently decided to use Drools in my project and being a newbie I
would greatly appreciate some input. The idea is to have a web application
that simulates home automation using rules. The user could define the
configuration of his home environment (based on virtual representation of
sensors and actuators), specify rules and execute them to see how the
configuration and the rules work together.
Seeing that I have very little experience with Drools I would like to know
how drools expert would perform if you should have 100 or more users using
the web app concurrently. In some other posts they suggest creating sessions
for each user in the knowledge base but the rules would not be the same for
each house so the knowledge base would essentially need to be different.
Should a new instance of a knowledge base be created for each user? Is there
a different way to do this since creating a knowledge base is supposed to be
"expensive"?
Sorry for the long post but I meant to give some context to the question
that could maybe help the experts. If anyone has had experience with such a
thing or can give me links to useful material it would be really helpful.
Regards

lock-on-active clarification needed
by Esteban Aliverti
Hi all,
I'm dealing with a set of rules having the lock-on-active attribute and I'm
not getting the (at least what I understand as) expected results.
I've created an isolated JUnit test. I'm attaching it to this email.
Basically, I have 2 rules:
rule "init"
lock-on-active true
when
$d: DataSample()
then
System.out.println("Setting predefined value");
modify($d){
addValue(Parameter.PARAM_A, 10.0)
}
end
rule "Rule 1"
lock-on-active true
when
DataSample($v: values[Parameter.PARAM_A] < 20)
then
System.out.println("Rule 1: "+$v);
end
DataSample is a Java class containing a Map<Parameter, Double> where
Parameter is an enum.
In the test I'm creating a ksession and inserting an empty DataSample
object.
I understand that as soon as the object is inserted, both rules are
evaluated and the result is going to be an activation of rule "init"; and
this is what is actually happening. So far so good.
Now, after I call fireAllRules() I expect that 'Rule 1' becomes active
because of the modification of the fact in "init". Well, this is not the
case. I don't see any activation for "Rule 1".
My understanding about lock-on-active is that a rule that WAS ACTIVATED is
not going to be re-activated until the current agenda group is switched.
The odd thing here is that I never had an activation for "Rule 1" so I
don't see why it activation after "init" is executed should be prevented.
So my question is: Is my understanding wrong? What is the expected behavior
of lock-on-active in this situation? I read the documentation but I
couldn't get any hint:
"
Whenever a ruleflow-group becomes active or an agenda-group receives the
focus, any rule within that group that has lock-on-active set to true* will
not be activated any more*; irrespective of the origin of the update, the
activation of a matching rule is discarded. This is a stronger version of
no-loop, because the change could now be caused not only by the rule
itself. It's ideal for calculation rules where you have a number of rules
that modify a fact and you don't want any rule re-matching and firing
again. Only when the ruleflow-group is no longer active or the agenda-group
loses the focus those rules with lock-on-active set to true become eligible
again for their activations to be placed onto the agenda."
Best Regards,
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
