Re: [rules-users] Guvnor Asset versioning vs Package snapshot versioning

2010-09-17 Thread Ed Lo

Thanks Abdel.
I tried it, I like the idea. It will be good to have the package snapshot
versions managed in Guvnor, if you have implemented this for your project I
will be interested.

   Yes, basically, if you are new to Drools, you get a nice exposure to it,
and if you are experienced with Drools, bring your questions/examples/etc
and it will be the perfect opportunity to discuss them face to face with
both the development team and other users. Although this is a short bootcamp
(1 day), it is a great opportunity to drink it from the fountain as there
will surely be other people there that will be able to help you with
whatever your needs are.

See you there,
Edson

[rules-users] Guvnor 5.1: Pencil icon not clickable in BRL editor‏

2010-09-17 Thread Scott Mayne















Hi all,

I'm reading Paul 
Browne's "JBoss Drools Business Rules" and in Ch. 5 we make a BRL in the guided 
editor. We're using a simple fact model with a single class (Sales) which has 
(among others) a field "sales", type long. The book uses an earlier version of 
Guvnor so things look a little different but everything's worked so far, until 
I 
use the editor to make a rule that looks like this in "view source":

rule 
"SalesDiscount"
  dialect "mvel"
  when
    mySales : Sales( salesValue 
: sales >= "100" )
  then
    mySales.setSales( salesValue-10 );
    
update( mySales );
end

When I try it out, I get this line in the THEN 
section

"1.  Modify value of Sales [mySales] sales [pencil icon] [remove 
icon]

but neither "sales" nor the pencil icon is clickable, so I can't enter what it 
should change to. When click view source using what I could do I 
get:

rule "SalesDiscount"
  dialect "mvel"
  when
    mySales : 
Sales( salesValue : sales >= "100" )
  then
    mySales.setSales( 
);
    mySales.setWait( );
    update( mySales );
end

[I added 
the "wait" because the modify field dropdown has this as an option but it's not 
in the Java class and I'm not sure where it came from.]

Can anyone shed light on this behavior? I'm using the latest version of 
Firefox, compiling 
with GWT/building my own EAR (though I haven't done any code changes) using RAD 
7.5.5.1 (based on Eclipse 3.4), and am running Guvnor on 
WebSphere.

The morning will be talks, for those that know Drools well, it will 
mostly be what they know. The afternoon will be an open workshop, this 
means people work through examples with us onhand to help. There are 
also more experience people there who are already working on their own

their code along with them. Those people will probably just code away in 
the morning, with one eye on the talks if anything interests them they 
haven't seen before. The other type of person are those wanting to 
actually hack on Drools internals adding news features.


You get the most out of the Day if you know what it is you specifically 
want and know how to ask it. What the day isn't is 8 hours of spoon fed 
step by step workshop tutorials that you would get on a training course.


In the past we used virtual machine images on a USB stick, but setting 
that up always caused a lot of problems. So this year I think we are 
going to provide bootable usb sticks with Fedora and Drools ready to go, 
so people can work through examples and just hack code.

Re: [rules-users] Perfromance issues and memory leaks in Drools

2010-09-17 Thread Edson Tirelli

Nikhil,

Maybe you are using the term "memory leak" loosely here, but otherwise,
Drools 4.0.7 and Drools 5.0.1 were both tested to exhaustion for memory
leaks and I can tell you that no memory leak was found, and I personally
doubt there is one there on regular use. Also, FYI, Drools 5.x eliminates
the need for shadow facts, what is a considerable memory save over 4.x, but
adds some other overheads for performance improvement that kind of offset
those gains. On the other hand, Drools 5.1.1 takes the algorithm to a new
level, saving a lot of memory on systems that use modify actions on their
rules.

http://blog.athico.com/2010/03/drools-halves-memory-use-with-new-true.html

Regarding your performance, all I can tell you is that a rules engine is
a relational engine that works pretty much like a database, and rules as
databases queries. The same way you can write SQL queries that run fast or
slow on a database, you can write rules that run fast or slow on a rules
engine. It all depends on how the rules/queries are written, how your data
model/domain model looks like, etc.

So, regarding your question, we can't tell you how to improve those
metrics without knowing your domain model, rules and etc.

Re: [rules-users] How to activate/deactivate a rule.

2010-09-17 Thread Ritesh


Thank you so much...  earlier I tried with both as below for each rule
with different salience values... but it was generating 4 exception as I
mentioned in my last email.

1.

agenda-group "init"

  auto-focus true

  no-loop true

salience 10 

  dialect 'java'

2.

  dialect 'java'

 

Now I am just using :

Rule 1

salience 100

  dialect 'java'

Rule 2

salience 50

  dialect 'java'

Rule 3

salience -1

  dialect 'java'

 

This is working just fine.

 

Thanks a lot..

Hi,

Thanks for the reply..

 

--The sequential option is set to false

--Using  StatelessKnowledgeSession

 

Summary what I intend to achieve,

1.  In first rule, I am doing calculation on three different columns
and putting it in sumOfThree property of ActualSum and inserting it in
WM. Let say I have four facts.
2.  In Second Rule, I am inserting distinct audit trail in
DistinctAT. Lets say I have two distinct AT.
3.  In Third Rule, I am assuming 4 Facts of ActualSum and 2 Facts of
DistinctAT already available in WM. Now I want to get sum of sumOfThree
group by AT, which I am trying to get using Accumulate function.

 

OutPut I am getting:

AT :1001

Done!

Done Main Rule, total :-40.0

AT :1000

Done!

Done Main Rule, total :210.0

AT :1000

Done Main Rule, total :160.0

AT :1000

Done Main Rule, total :260.0

 

INFO: Number of generated exceptions   4

 

Here I see the last rule is getting fired every time ActualSum fact is
inserted in first rule. And as the facts are available one by one, these
are available to Accumulate function used in third Rule. Actually I am
expecting only two exceptions one for AT:1001 and AT:1000 with total of
-40 and 260 resp.

 

Please advise.

 

P.S.  Please ignore "$lfna_SEI and $r_SE".

Have you tried running what you have?

 

I'd expect it to give the result you expect already (other than throwing
an error because $lfna_SEI and $r_SE are not bound in the last rule and
assuming chkRuleExpre is constant over time). Rules do not normally
execute in any sequential order (unless you explicitly make them so). As
the facts are inserted into WM they are matched against your rules and
activations scheduled. When all facts are inserted into WM and you call
fireAllRules the activations are played out and "truth maintenance"
ensures the "result" of their firing is consistent with the facts in WM
(either inserted by rules or the programmer). This is in essence "how
inference engines" work.

 

After you've called fireAllRules (and assuming you have a stateful
session) you insert more ABC's then you'd have to expect the last rule
to be re-evaluated - following another call to fireAllRules. So in part
when rule 3 ultimately gives the "correct" answer depends upon when you
stop inserting ABC's.

I think this overly complex (unless other things have to be considered
as well.

As I interpret these three rules, it is required to compute the sum
of all values ABC.C with equal ABC.A

declare DistinctAT
d_auditT : String
d_sum: Double
end

rule "create DistinctAT on first ABC"
when
ABC( $a:A )
not DistinctAT( d_auditT == $a )
then
DistinctAT $disAT = new DistinctAT();
$disAT.setD_auditT($AT);
insert( $disAT );
end

rule "update d_sum in DistinctAT"
when
$disAT: DistinctAT( $a: d_auditT )
ABC( A == $a, $c:C )
then
$disAT.setD_sum( $disAT.getD_sum() + $c*0.13 );
end

Notice that I do not update/modify $disAT in the second rule since this
would cause a loop.
If you need the update to fire other rules, add "no-loop true".

To get all results, you can use a query; run it after all ABCs have been
inserted.

[rules-users] Perfromance issues and memory leaks in Drools

2010-09-17 Thread 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

Re: [rules-users] How to activate/deactivate a rule.

2010-09-17 Thread Wolfgang Laun

I think this overly complex (unless other things have to be considered as
well.

As I interpret these three rules, it is required to compute the sum
of all values ABC.C with equal ABC.A

declare DistinctAT
d_auditT : String
d_sum: Double
end

rule "create DistinctAT on first ABC"
when
ABC( $a:A )
not DistinctAT( d_auditT == $a )
then
DistinctAT $disAT = new DistinctAT();
$disAT.setD_auditT($AT);
insert( $disAT );
end

rule "update d_sum in DistinctAT"
when
$disAT: DistinctAT( $a: d_auditT )
ABC( A == $a, $c:C )
then
$disAT.setD_sum( $disAT.getD_sum() + $c*0.13 );
end

Notice that I do not update/modify $disAT in the second rule since this
would cause a loop.
If you need the update to fire other rules, add "no-loop true".

To get all results, you can use a query; run it after all ABCs have been
inserted.

Check the drools introduction at 
http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-introduction/html/ch02.html#d0e63
chapter 2.1.2.2. 

It has a nice configuration example.

Re: [rules-users] How to activate/deactivate a rule.

2010-09-17 Thread Michael Anstis

Have you tried running what you have?

I'd expect it to give the result you expect already (other than throwing an
error because $lfna_SEI and $r_SE are not bound in the last rule and
assuming chkRuleExpre is constant over time). Rules do not normally execute
in any sequential order (unless you explicitly make them so). As the facts
are inserted into WM they are matched against your rules and activations
scheduled. When all facts are inserted into WM and you call fireAllRules the
activations are played out and "truth maintenance" ensures the "result" of
their firing is consistent with the facts in WM (either inserted by rules or
the programmer). This is in essence "how inference engines" work.

After you've called fireAllRules (and assuming you have a stateful session)
you insert more ABC's then you'd have to expect the last rule to be
re-evaluated - following another call to fireAllRules. So in part when rule
3 ultimately gives the "correct" answer depends upon when you stop inserting
ABC's.
