Re: [rules-users] Guvnor cluster problems

2011-11-23 Thread jayadev

I use database as the store for assets. I was thinking of asking DBA's to
just wipe out all the tables and then re-import. I am assuming the export is
healthy because when I imported it into a test environment it worked well. 

I am not too concerned about getting things back up. I am more concerned
about how did they ever get out of sync. Why did they get out of sync!!??
Shouldn't there be a warning or something so that users know about the
possible sync issues. Is there a way to find out which assets add/update
didnt make it to journal?

Re: [rules-users] multi-factor rule

2011-11-23 Thread Welsh, Armand

Sorry to repost again  But I also realized after sending that if you have 
to exclude locations A, B, and C from the else rule, then you do not need 
salience, nor activation group, since all the rules are not mutually 
exclusive..  This this (much easier too now)


rule 'Rule One'

when

Person (location == 'A',  age > 60 )

Then

do_something();

end



rule 'Rule Two'

when

Person (location == 'B',  age > 70 )

Then

do_something();

end



rule 'Rule Three'

when

Person (location == 'C',  age > 80 )

Then

do_something();

end



rule 'Rule Else'

when

Person (location not in ('A','B','C'), age > 65 )

Then

do_something();

end

This is a good example why it can be difficult to model rules from procedural 
language.  With a rule, you are reacting to a given condition, but with 
procedural language waterfall logic, you automatically exclude conditions as 
you fall through the logic.  With rules, there is not waterfall effect.  You 
have to simulate the waterfall logic with explicit exclusions.

This is best represented with a lot of if() but no else clauses in procedural 
language logic.

Not the only rule I modified to make this work was my else rule.

Re: [rules-users] Guvnor cluster problems

2011-11-23 Thread Welsh, Armand

If you know that your export is good, then you could backup the directory that 
contains your guvnor repository (rename it) while guvnor is off-line.

Then start guvnor with an empty repository -- this will force guvnor to 
initialize the repository.  

Next simply launch Guvnor, and import your repository.

Again, backup your existing repository so you don't lose anything. And this 
requires that your exported repository is in fact healthy.

Re: [rules-users] multi-factor rule

2011-11-23 Thread Andreas Schlüter

Hi,

you might try something like one of the following two variants:


a) Checking for Location only first, inserting a Fact for the respective
location and doing a second rule for each location that checks for this fact
and the age (using salience to ensure only one rule fires and this in the
correct order).
In this case, exactly one of the rules without the additional facts will
fire:
 - if it is one of the first three, it will fire first,  then after that the
rule with the additional fact will fire and give the correct result
- else, your "else" rule fires right away.


b) using different agenda-groups for the different locations and setting
focus to the location-specific agenda-group in a first step. If I get it
correctly (I am a newbie too and don't have the time to try it out), this
should work.


True, you have two rules for each location, but I find this acceptable:
- Rules should be simple and (close to) declarative
- If I read your requirements correctly, you typically filter on location,
so in the long run, there will be location-specific agenda-groups anyway if
you build a complete rule base.

Variant B could look like this:

rule "Rule One"
activation-group "CheckLocation"
salience 300
when
Person(location == "A" )
Then
drools.setFocus("Location-A");
end

rule "Location A: age>60"
agenda-group 'Location-A'
when
 Person(age>60)
then
  do_something();
end

rule "Rule Two"
activation-group "CheckLocation"
salience 200
when
Person(location == "B" )
Then
drools.setFocus("Location-B");
end

rule "Location B: age>70"
agenda-group "Location-B"
when
 Person(age>70)
then
  do_something();
end

rule "Rule Three"
activation-group "CheckLocation"
salience 100
when
Person(location == "C" )
Then
drools.setFocus("Location-C");
end

rule "Location C: age>80"
agenda-group "Location-C"
when
 Person(age>80)
then
  do_something();
end


rule 'Rule Else'
activation-group "CheckLocation"
salience 0
when
Person (age > 65 )
Then
do_something();
end

Re: [rules-users] Multiple Insert and negative rule

2011-11-23 Thread Welsh, Armand

As an aside note.  You may want to consider re-working your rules to never use 
the || condition.  

It's not that this is inherently bad, but that the any logical ORs mean that 
you are actually representing more than one rule within the singular rule.  
This can make mapping the logic to the rules difficult in the future.

Hi,

Probably it is because you are using NOT (). The engine will not fire this rule 
for every event in the WM. 

Consider changing from 
not ( Event( system == "any" ) ) to 
Event( system != "any" )

That will force the engine to execute it for each Event in memory.

Re: [rules-users] multi-factor rule

Try this:

activation-group 'age-test'
salience 300
when
Person (location == 'A',  age > 60 )
Then
do_something();
end

rule 'Rule Two'
activation-group 'age-test'
salience 200
when
Person (location == 'B',  age > 70 )
Then
do_something();
end

rule 'Rule Three'
activation-group 'age-test'
salience 100

Then
do_something();
end

rule 'Rule Else'
activation-group 'age-test'
when
Person (age > 65 )
Then
do_something();
end


This will do what you want, and the first rule that matches will cancel the 
activation of any other rules that matches.  However, because these rules are 
not mutually exclusive,  this is not the best way to represent the logic, since 
a change to person could cause the wrong rule to fire, since only the rules 
that are affected by the change would be re-activated.

The EASIEST way to represent this is with an Excel Spreadsheet (or the Guvnor 
Decision Table).  Then you can craft the table to identify each rule 
exclusively, and use the otherwise keyword to deal with the negation of all 
specified facts.  If you can represent your rules without requiring salience as 
the conflict resolver, then you will have better (more predictable) rules, 
since this would mean that only one of the group rules could ever be true at 
any instance in proessing.

Re: [rules-users] How to use contains with a function

2011-11-23 Thread Welsh, Armand

Wrap in in ()'s like this:

$tc : TaskContext( times contains (getTimeByID(ETimeID.NOW)) )

I have not personally tried this exact scenario, but the concept is the same as 
other scenarios I use this for.  The ()'s identifies that evaluation should be 
used here, except that it's not really an eval() because the contents don't 
returne true/false, but rather it's just java code to be processed, and the 
output can then be used in the evaluation.

I do this with matches like this:

LookupFact ( $lookupValue : value )
$sf : SomeFact ( value matches ("(?i)" + $lookupValue) )

Subject: [rules-users] How to use contains with a function

Hi all,

I encountered the following issue:

As an example TaskConectxt() holds a list of time related objects called times.
I would like to write a rule which ideally would filter the TaskContext 
according  to a specific time object.
The problematic restriction is that this time object is derived using a helper 
function (imported), in this case called getTimeByID which received as input an 
enum ID of a time and returns the desired time object.

Ideally the rule would like something like this:

rule "verify time"
  when

$tc:TaskContext(times contains 
getTimeByID(ETimeID.NOW))
  then
//something
end

unfortunately this does not work.
Is there any way to call a function with a param?
Is there a better alternative method than this one?

Thanks,
Hezi

Re: [rules-users] How can I import a drl file in a package in duvnor?

2011-11-23 Thread Welsh, Armand

Yes.

The DRL file must either specify the package name that it will be imported to, 
or the package declaration line must be missing completely -- when missing 
Drools Guvnor prompts for the package name.

To import DRL, select the option to create a new Package.  Then select the 
radio button for import, and select your other DRL file.

Guvnor will merge your DRL into the existing package.  If any rules in the new 
DRL file have the same name as an existing rule, then the rule being imported 
will become the next revision of the rule guvnor (replacing the old rule with 
the new one).

Armand

Re: [rules-users] Guvnor cluster problems

I dont see any SQL Exceptions in the log, probably means that all journal
entries did make it to database. How can I figure out how/when/for how long/
the sync messages got lost? I have logs enabled at INFO and I dont see any
WARNING's or ERROR's.

Re: [rules-users] string replace collision problem

2011-11-23 Thread FrankVhh

Hi,

Sorry, but I fogot about you :-(.

It does not work because both wolfgang and I did get your question wrong.

If I were you, I would try to work from the opposite direction and check
whether a String matches S but not SF. Than replace that S by VOL.

A second rule could than safely check for SF and replace that by S.

In short, reverse your salience, check that S is not SF and make sure that
you replace the right S in the RHS of your rules. You do not want to update
the WM.

Regards,
Frank

Re: [rules-users] multi-factor rule

2011-11-23 Thread FrankVhh

Hi,

If you do not want to check for all alternative cases, you might need a
showstopper to stop the firings of unwanted rules.

This can be achieved by executing insert(new ShowStopper() ); in your RHS.
All LHS of the rules will check for not( ShowStopper() )

Alternatively, you can use the new -experimental - feature of drools called
"declarative agenda". You could use this to block activations of rules
directly.

Also, be aware that relying on salience alone is very hard to maintain over
time.

Frank

rule "test2"
salience 5
 when
  not ( Event( (system == "anySystem" && catagory == "anyCatagory" ) ||
(system == "anyHost" && message matches ".*Hello.*")))   
 then

Hi,

Probably it is because you are using NOT (). The engine will not fire this
rule for every event in the WM. 

Consider changing from 
not ( Event( system == "any" ) ) 
to 
Event( system != "any" )

That will force the engine to execute it for each Event in memory.

Frank

Re: [rules-users] Rules that cumulate on consequence

2011-11-23 Thread Vincent Legendre

It will work properly in a stateless session ... in sequential mode ... 
may be.
This rule for instance, will loop by itself (and all other will also 
loop), in a stateless or statefull session :


rule "one"
when
$r : Result( $score : score )
Applicant( numberOfLoans > 1 )
then
$r.setScore( $score + 5 );
update( $r ); // update $r, so re-trigger the rule, which 
re-update $r, etc etc etc ...

end

May be a no-loop could work, but no-loop is dangerous (hard to 
debug/maintain, and does not handle cycles between rules firing, ie 
"rule one" will trigger "rule two", which will trigger "rule one" again 
etc etc)


The second set of rules could be better, if modified that way (test is 
the updated field is null in conditions)

rule "one"
salience 100
when
$r : Result(*numberOfLoans == null*)
Applicant( $nl : numberOfLoans )
then
$r.setNumberOfLoans( $nl );
update( $r );
end
 ...

Another option is to add some flags in the Result object, holding the 
fact that a rule (or a rule group, for instance the rule group that 
manage the numberOfLoans, another the income ...) has been fire, meaning 
that the corresponding applicant attribute has been taken into account. 
This flag is used in the conditions to exclude all other rules in the 
same group.


May be a last option is something that I already use for a use-case 
close to this one. This was about computing counter (agregate a value in 
a single object, and avoiding infinite loop), then check them (so I need 
the updated value). My solution was a rule-flow with 3 boxes :  [compute 
counter]->[update counters in RETE]->[check counters].
The main trick is to update the value but not the object in  [compute 
counter] group, like this


rule "one"
when
$r : Result()
Applicant( numberOfLoans > 1 )
then
$r.addScore( 5 );
end

-> $r fact is not updated in RETE here, so no infinite loop problem
-> The main point to care about is to avoid getting the actual score in 
condition, but uise the getter in the action part. Indeed, as the $r 
fact is not updated, the original binding would be kept and all 
"computing" rules will update the same initial value (so forget about 
agregate).



Then update all Results in [update counters in RETE] group :
rule "update_results"
when
$r : Result()
then
update ( $r );
end

-> this will update all object for their further use for validation rules

And finally, use your Result object with score updated to perform other 
actions in the [check counters] group :


rule "decide_reject"
when
$r : Result(decision == null, score < 25)
then
$r.setDecision( Decision.REJECT );
update ( $r );
end

-> Note the null check to avoid loops, again ...

the trick is to do an insertLogical of a ScoreDiff instead of setScore()

In DRL terms it'd look like this:-

rule "one"
when
$r : Result( $score : score )
Applicant( numberOfLoans > 1 )
then
$r.setScore( $score + 5 );
update( $r );

rule "two"
when
$r : Result( $score : score )
Applicant( disposableIncome < 2 )
then
$r.setScore( $score + 10 );
update( $r );
end

The result could equally just contain the factors influencing the 
score with a low salience rule then calculating the final score:-


rule "one"
salience 100
when
$r : Result()
Applicant( $nl : numberOfLoans )
then
$r.setNumberOfLoans( $nl );
update( $r );
end

rule "two"
salience 100
when
$r : Result()
Applicant( $di : disposableIncome )
then
$r.setDisposableIncome( $di );
update( $r );
end

rule "calculate score"
salience 200
when
$r : Result( $nl : numberOfLoans > 1, $di : disposableIncome 
< 2 )

then
$r.setScore( 20 );
update( $r );
end

[rules-users] How to use contains with a function

2011-11-23 Thread Hezi Stern

Hi all,

 

I encountered the following issue:

 

As an example TaskConectxt() holds a list of time related objects called
times. 

I would like to write a rule which ideally would filter the TaskContext
according  to a specific time object.

The problematic restriction is that this time object is derived using a
helper function (imported), in this case called getTimeByID which received
as input an enum ID of a time and returns the desired time object.

 

Ideally the rule would like something like this: 

 

rule "verify time"

  when



$tc:TaskContext(times contains
getTimeByID(ETimeID.NOW))

  then

//something 

end

 

unfortunately this does not work. 

Is there any way to call a function with a param?

Is there a better alternative method than this one?

 

Thanks,

Hezi

[rules-users] multi-factor rule

2011-11-23 Thread Ronald Albury

Hi - I am a Drools newbie and I apologize in advance if the answer to my
question is intuitively obvious to the casual user.

I have an object that has two fields: location(there are more than 50
locations) and age.  I am having difficulty building clean rules for the
following pseudo-code


// Rule One
if(location == "A") {
   if(age > 60)
  do_something();
}
// Rule Two
else if(location == "B") {
if(age > 70)
do_something();
}
// Rule Three
else if(location == "C") {
if(age > 80)
do_something();
}
// Rule Four
else {
if(age > 65)
do_something();
}

The issue comes with Rule Four.  How do I avoid writing the rule so that I
don't have to say (location!="A"&&location!="B"&&location!="C") ?  I also
don't want to have to write an explicit rule for every possible location.

I considered an activation-group with salience to have the rules executed
in order, but the problem is that if rules 1-3 do not fire, then rule 4
fires for all locations - I can get a hit if location=="C" and age==70.

Is it possible to have a 'Map' and do something like
(age>map.get(location)) ?  I could live with creating a map with all
possible locations for key, although I'd rather not go this route.

This problem is typical for the types of rules I'll be writing ... there
can be completely different sets of rule criteria depending on location.


Thanks in advance for your suggestions and your patience.

Re: [rules-users] How to change Guvnor language?

2011-11-23 Thread Michael Anstis

Guvnor is localised to the following locale:-

   - es_ES
   - fr_FR
   - ja_JP
   - pt_BR
   - zh_CN

The default language for messages etc when no locale is provided (or is
unavailable) is English.

Provided you are using the downloaded WAR, or you have compiled from source
using the "full" profile you should be able to append the required locale
to your URL.

e.g. http://127.0.0.1:/org.drools.guvnor.Guvnor/Guvnor.html?locale=es_ES

You can also use the Guvnor.jsp page that uses the HTTP request header
locale setting (that should be set by your browser).

e.g. http://127.0.0.1:/org.drools.guvnor.Guvnor/Guvnor.jsp
