[rules-users] Remote debug as Drools App on Eclipse
Good day everyone, sorry if this is a basic question. I'm using eclipse and I know that you can debug an App as a Drools application to be able to debug the .drl contents. I have always used this feature on apps that reside on my local machine. I have also used the "Debug as a Remote Java Application" feature within eclipse, however, I honestly don't know how to Debug a Remote App as a Drools Application; is it possible?? Thanks a lot in advance for your time. -- View this message in context: http://drools.46999.n3.nabble.com/Remote-debug-as-Drools-App-on-Eclipse-tp3924515p3924515.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] please provide a rule for events timeout cases
With this kind of scenario it helps a lot if you retract a matching
pair (R+S, R+F). (If you need the information for further processing,
create another fact.)
And make sure to use '==' when testing for equality!
rule request_success
when
$req : EventRecord( type == EventRequest, $user: user)
$resp : EventRecord( type == EventResponseSuccess, user==$user,
this after[0s.10s] $req )
not EventRecord( type == EventResponseSuccess || == EventResponseFailure,
user == $user, this before $resp )
then
// success
retract( $req );
retract( $resp );
end

Re: [rules-users] please provide a rule for events timeout cases
without the error trace, hard to say why it crashes ...
But your rules can be simplified/clarified :
- "and" to connect conditions is not needed
- in your first 'not' condition, which you add to test that no other event
takes place between the two objects matched in previous patterns, you should
test the two response types, as you don't want *any* response ...
- again in your first 'not' condition, the after/before should not be in a
interval. Why not using after/before only ? For timeout ? Should be a third
rule to me ... and should add a rule to handle response coming after the
timeout too.
- I cant see the utility of you second 'not' pattern (may be because of my
previous remarks)
Another question : why don't you retract the response too ? Is it because you
want to keep them ?
To me it is better to retract it, especially if it takes place between another
initial EventRequest and its response. at least mark the response as treated
and ignore the treated responses in your conditions
So, your rules will become 2 groups of rules : first group to handle the
response that correspond to a request, second group to handle the timeout cases
:
rule event_success_case
when
$req : EventRecord( type=EventRequest, $user : user )
$resp : EventRecord( type=EventResponseSuccess, user=$user, this after
$req )
not (EventRecord( type=EventResponseSuccess || EventResponseFailure,
user=$user,
this != $resp, this after $req , this before $resp)))
# 'this != $resp' is not mandatory as you test after/before (which are
strict), but it does not harm ...
then
System.out.println("Success case for user " + $req.getUser());
retract($req);
retract($resp);
end
rule event_failure_case : same but testing the other status
rule event_timeout_case
when
$req : EventRecord( type=EventRequest, $user : user )
not (EventRecord( type=EventResponseSuccess || EventResponseFailure,
user=$user,
this after[0,10s] $req))) // assuming 10s for timeout
then
System.out.println("Timeout case for user " + $req.getUser());
retract($req);
end
rule event_response_after_timeout_case
when
$resp: EventRecord( type=EventResponseSuccess || EventResponseFailure,
$user : user )
not (EventRecord( type=EventRequest, user=$user,
this before $resp)))
then
System.out.println("Response coming after timeout case for user " +
$req.getUser());
retract($resp);
end

Re: [rules-users] Performace Issues drools
This may no longer be the case, but my understanding is that when you use from to query data from a member list of another object in working memory, that those members are not indexed by Rete. I think every time the rule evaluates, it has to iterate through the entire member list (collection) to find the matching facts that are extracted for additional evaluation. With that said, if you have one rule that extracts the facts, and inserts them into working memory, they will be indexed and now many operations on the fact type will be pre-computed at the time of insert, improving performance dramatically. I don't know if this makes sense, but consider the following: CONDITION: $pt: Patient ( ) LabTest( ) from $pt.labTests $numTests: Number ( ) from accumulate ( LabTest($type: type == "lab"), count($type) ) Drools first collects all the Patient facts and for each Patient it extracts the collections of tests. Now the collection of patients are already known by Rete, so this has been pre-computed at time of fact insert. Next, for each Patient fact, drools extracts the collection of LabTests performed. These are not indexed by Rete to they are not actually in working memory. Each time this rule is evaluated, the collection of LabTests must be generated. Next the accumulate evaluates the LabTest facts to find those that have a getType() == "lab". Since the facts do not exist in working memory, accumulate iterates all the LabTest fact and extracts just the ones where getType == "lab". If the rule file 10 times, that's 10 iterations of the collection. If you break this into two rules: CONDITION: $pt: Patient ( ) $test : LabTest( ) from $pt.labTests CONSEQUENCE Insert($test); CONDITION: $numTests: Number ( ) from accumulate ( LabTest($type: type == "lab"), count($type) ) In this scenario, Drools only extracts the LabTest facts once, and inserts them in working memory, so that when the 2nd rule is evaluated, it is already known which LabTest facts are in memory that exist, and the iteration only happened once, at insert time, instead at every rule evaluation. My understanding may be obsolete, and inaccurate as it applies to Drools 5.4, but this is the type of coding changes I have made in the past to improve performance. The key is knowing how to control the insertion rule, so it does not insert duplicates, or refire unexpectedly. Care must be taken to ensure you are properly binding your facts when you do this though... But the most speed benefit in drools comes from using the rete engine to avoid multiple iterations of the same collection... -Original Message- From: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] On Behalf Of sanal Sent: Tuesday, April 17, 2012 4:27 AM To: rules-users@lists.jboss.org Subject: Re: [rules-users] Performace Issues drools Hi, Still Iam facing some issues with the accumulte.Please see the below senario.I am trying to explain with the below example. Suppose Glucose is a OrderedComponent which is under Labgroup.

In this case no rule exist for glucose. 2) If no rule is found for the Orderedcomponent.I need to Check if any rule exist for its parent(group). I am trying to achive this by changing the component key. The component key is changed to that of the parent and the rules are executed once again.This process is contiuned until any rules exist for the group or root parent is reached(tree format). 1st Issue Here parent of glucose is Lab. And Lab has got rule.So the Parent rule of lab should get executed. In this senario only 2 glucose orders should go under package. 3rd one should not go under package. With my existing Drl all the 3 are going inside the package.How can i correct this? 2nd Issue While accumulating with lab group,all ordered items whose parent group is lab should be summed up.

Re: [rules-users] please provide a rule for events timeout cases
"Immediate response" is one way of saying that there is no other
response between a request and a response for one user. Simply add
this condition, testing for both kinds of response.

[rules-users] StatefulSession finalize() memory question
I'm just beginning at a project that is using Drools in a Desktop application, currently V 5.2.0. This is my first contact with Drools. My first task was to analyze the application's memory usage. I noticed that there were quite a number of ReteooStatefulSession's hanging around on the Finalizer queue--they never do get GC'd (at least not in normal operation). My question is the motivation for implementing StatefulSession's with a finalize() method. My understanding is that it is best practice to call dispose() in any case, when finished with the session. I built drools-core here locally and removed the finalize() method which had the desired effect--no Sessions on the Finalizer queue. The application uses rules as the logic behind data entry masks. One rule per mask type, one session per mask instance. There may be several instances of a mask type active at any time.

Re: [rules-users] please provide a rule for events timeout cases
Hi,
Now time out is working fine.
But facing issues for correlating success and failure events which doesnot
have unique id. I want to correlate an event request followed by its
immediate event response.
Ex: Consider the events in below order
EventRecord( type=EventRequest, user="katta" )
EventRecord( type=EventResponseFailure, user="katta" )
EventRecord( type=EventRequest, user="katta" )
EventRecord( type=EventResponseSuccess, user="katta" )
Rules:
rule event_success_case
when
$req : EventRecord( type=EventRequest, user="katta" )
and EventRecord( type=EventResponseSuccess, user="katta", this after[0s,
10s] $req )
then
System.out.println("Success case for user " + $req.getUser());
retract($req);
end
rule event_failure_case
when
$req : EventRecord( type=EventRequest, user="katta" )
and EventRecord( type=EventResponseFailure, user="katta", this after[0s,
10s] $req )
then
System.out.println("Failed case for user " + $req.getUser());
retract($req);
end
In the above example I don't have any unique identity to correlate request
and response. I need to correlate only based on events order.
In the above example events order is EventRequest --> EventResponseFailure
and then EventRequest --> EventResponseSuccess. So my expected output is:
Failed case for user katta
Success case for user katta
But I am getting below response:
Success case for user katta
Success case for user katta
First EventRequest and second EventRequest are correlating with second
response EventResponseSuccess as this response is within 0 to 10sec for both
events.
Note: I am getting expected result only when I send few events. If I insert
around 50 events at time into Working Memory, I face this kind of unexpected
result.
I need to work on live trafic, where I receive hurends of messages per
second.
