Fwd: Early bird registration ENDS TODAY: Rules Fest 2010
by Edson Tirelli
Hey people,
I am glad to see that people are registering for the bootcamp (and the
conference)! Hope to meet you all there! If you've never been to Rules Fest
before (this is the 3rd year it is happening), it is the only technical,
no-fluff, conference in Rules Engines and related technologies that I know
of. I had a great time last 2 years and I know it will not be different
this year.
And for those that did not registered yet, just a reminder, the early
bird discount ends today as per the e-mail bellow.
Edson

Perfromance issues and memory leaks in Drools
by Nikhil S. Kulkarni
Hi,
I have written 2 different Drools programs. One is with Using rule Base of Drools 4.0 and other is using Knowledge Base of Drools 5.0.
I was trying to check that is there any improvement in Drools 5.0. But I haven't got any performance improvement in Drools 5.0 code compared to Drools 4.0.
One more important thing is I am calling this drools code from My application which itself is heavy application, when I am doing Performance tuning
I got one point i.e. session.execute() method is taking around 6-7 seconds to initialize rules and even the memory utilized by Rules is huge.
So is there any way that we can reduce the Memory leakage and improve performance.
Waiting for Reply.
Thanks & Regards,
Nikhil S. Kulkarni

by Ritesh
Hi,
I have 3 rules in my drl file and want the last one should get fired only
after all the facts in rule1 and rule2 gets inserted in working memory.
Please see below code for more understanding. Please suggest.
Thanks
declare DistinctAT
d_auditT : String
end
declare ActualSum
auditT : String
sumOfThree : BigDecimal
end
rule "insert combined sum"
dialect 'java'
when
ABC( $a:A, $b:B, $c:C )
then
BigDecimal actSum = $c.multiply(0.13);
ActualSum $as = new ActualSum();
$as.setAuditT($a);
$as.setSumOfThree(actSum);
insert($as);
System.out.println("AT :" + $movAuditT);
end
rule "insert distinct AT"
dialect 'java'
when
$a : ActualSum( $AT : auditT )
not DistinctAT( d_auditT == $AT )
then
DistinctAT $disAT = new DistinctAT();
$disAT.setD_auditT($AT);
insert($disAT);
System.out.println("Done!");
end
rule "Get Sum Group by AT"
dialect 'java'
when
DistinctAT( $dAT: d_auditT )
$total : Double()
from accumulate( ActualSum( auditT == $dAT, $actSum_Main : sumOfThree ),
sum( $actSum_Main ) )
eval(
chkRuleExpre( $total,$lfna_SEI,$r_SEI )
)
then
System.out.println("Done Main Rule, total :" + $total);
end

Memory leak error when deploying Guvnor in Tomcat
by bbarani
Hi,
I am getting the below now and then when I try to export the repository from
one system to another system (move the repository folder / repository.xml
file present in bin folder of tomcat to tomcat bin folder of another
system). Can someone let me know what might be the root cause of this issue.
Sometimes it works fine after migrating the above folders / files but most
of the time I am getting the below error.
SEVERE: A web application registered the JBDC driver

Re: [rules-users] EntityManager is closed
by Eugenio Abello
I have the same problem with drools 5.2 Using JPA with tomcat on bitronix.
I temporarily resolved with:
env.set (EnvironmentName.CMD_SCOPED_ENTITY_MANAGER, emf.createEntityManager
());
Every time I use the session.

URGENT - using lock-on-active or not
by Yaniv Itzhaki
Hi All,
I have an urgent problem which I hope someone can explain it to me and how
it can be solved.
I created 2 rules "Update 1" and "Update 2", basically the rules are the
same, get all the CaseLog objects according to "Category" and "Value" and
update the Case, which holds a list of CaseLogs, with a new object.
Note that in the update method I am updating the working memory by
retracting the old log and inserting the new one.
Now for the problem:
The problem is that on one hand, when I insert a new log line all rules
without lock-on-active re-fire. On the other hand, rules with lock-on-active
seem to disregard the addition of the new object and fire only on the lines
that were present when their group was activated.
Please see the rules below
Thanks
Yaniv
* *
*rule* "Update 1"
*salience* 4
*ruleflow-group* "group1"
*lock-on-active*
*when*
$case : Case()
$myLog : CaseLog( myClass == "Category",
myValue == "1" )
*then*
System.out.println("Logic: Update 1");
$case.update($myLog,40.0,*null*);
*end*
*rule* "Update 2"
*salience* 0
*ruleflow-group* "group1"
*lock-on-active*
*when*
$case : Case()
$myLog : CaseLog( myClass == "Category",
myValue == "1", $score : myScore )
*then*
System.out.println("Logic: Update 2 " + $score + 5.0);
$case.update($myLog,$score + 5,*null*);
*end*

On Entry On Exit actions question
by Gustavo Tenrreiro
Hi,
When using an "Email" node for example, where On Entry, and On Exit
actions are available. If I create an object within the On Entry
action ( Let's say a list of recipients for the email ), how do I
access that data from the body of the email ? What is the best
strategy to access data that was created on the On Entry action, from
the node itself ?
Thanks
