Objet: [rules-users] Inconsistent behaviour of insertLogical in rules having
from pattern
Hi all,
It is 2 days I am fighting with a strange behaviour of insertLogical in rules
having from pattern in conditions : it works the first time, and not after ...
-
Here is my use-case (simplified) :
I have a class that represent a Flight. A Flight has a start/end datetime and
is associated with a Airplane and a list of Crew :
class Flight {
String airplaneId;
ListString crewIds;
Date start;
Date end;
}
I want to maintain an alert list that contains all overlaps for each airplane
and each crew. So I have rules like:
rule Overlap Airplane
when
$f1 : Flight($airplaneId : airplaneId)
$f2 : Flight(this != $1, airplaneId == $airplaneId, ... and periods
intersecting ... )
then
insertLogical(new Alert(...));
end
rule Overlap Crews
when
$f1 : Flight()
$crew : String from $f1.getCrewIds()
$f2 : Flight(this != $1, eval($f2.getCrewIds().contains($crew)) , ...
and periods intersecting ... )
then
insertLogical(new Alert(...));
end
-
Ok. So what I do to test all that stuff :
- create a new session
- add a first single Flight -- no alerts at all, normal
- add a second Flight insersecting the first one with same airplane and
same crews list -- 3 new alerts inserted (one for airplane, one for each
crew) : normal
- remove this second Flight -- the 3 preivous alerts are retracted : still
ok
- re-add this second Flight -- only the 'airplane' rule triggers, I only
get one new alert insteads of the previous same 3 The alerts not
inserted correspond to the rule having 'from' in it
-
To test that it is the source of the problem, I add a new explicit
association object that I insert in WM :
class CrewAffectation {
String idCrew;
String idFlight;
}
For each inserted Flight, I also insert corresponding new CrewAffectation
objects. (in case of retract, I retract them of course).
I change the last rule to something like :
rule Overlap Crews
when
$f1 : Flight($id1 : id
$f2 : Flight(this != $1, $id2 : id, ... and periods intersecting ... )
$crewAff1 : CrewAffectation($idCrew : idCrew, idFlight== $id1)
$crewAff2 : CrewAffectation(idCrew == $idCrew, idFlight== $id2)
then
insertLogical(new Alert(...));
end
And with this 'no-from' approach, everything is working as expected.
-
In addition, I suspect the truth maintenance system to have leaks, and
notably in the source kBase.
Why ? Because I was facing problems by reusing the same kBase to generate
multiples kSessions : The first session created reacted well, while all the
folowing not.
And it was in fact the same problem as the one described here : usage of from
and insertLogical in the same rule.
The first created session adds and retract my 3 alerts, the second created
session only adds the airplane alert.
With using the explicit association object, I can reuse my kBase and
everything is working well.
-
Does someone already faced the problem ?
Does it looks like a real bug to dev team or am I doing something wrong (but
as it work once, I guess it is a bug) ?

A little more detail on what I'm trying to do: I am scheduling a series of classes and related activities on a calendar. Let's say I have some class BA101 that occurs several times a week (these classes are immovable entities). There are homeworks, exams etc. associated with these classes which I need to schedule. E.g. on Feb 1st, a homework might be due, or on Mar 1st, there might be an exam. So I need to schedule time to do the homework or time to study for the exam. My initial solution for this would be very simple: I would schedule the homework/study time at the same time of the class itself, and let optaplanner move it around till it meets my hard soft constraints. However, when I tried to do that (i.e. give my homework/study tasks an actual start time instead of just leaving the start time as null), OptaPlanner fell right through without actually making any moves to find the best score.

Re: [rules-users] Starnge problem with AbstractKieModule while testing, ignores classes folfer
The logic for what’s going on can be found here: https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/main/java/org/drools/compiler/kie/builder/impl/ClasspathKieProject.java Typically the code is looking for the kmodule.xml in a META-INF. When it finds it, it goes the root of that. There isn’t any logic to handle dual roots. I’m assuming you put the kmodule.xml in the test/resources/META-INF folder? What we might be able to do is see if there parent is “target” and if there is a child classes and test-classes and treat it as a special case.

in 6.x you do not necessarily have to set the salience any more. As LoadOrder is applied, and rules will be evaluated by the order of position within the file.

My next question is, please: is it possible to submit a JIRA on jboss.org and keep it confidential ? Or at least keep confidential the reproducer? Not on JIRA, but you can open a jira and then provide a dropbox link to Mario, Myself or Edson. The problem I'm facing, assuming I eventually develop the reproducer, that I seriously doubt my friends would agree in sharing this rulebase on a public domain - on other occasions it was okay to share the rulebase, while on other occasions the rulebase was limited so I translated the rulebase to another domain. My ultimate goal here would be to reach a compromise where I can deliver you guys of the drools team a precise reproducer, while at the same time keep my friends happy that the rulebase is not actually shared on public domain and kept confidential only for the scope of reproducing the bug. So my friends questions will likely be: 1. is there a process to raise a jira on jboss.org with confidential content ? 2. which terms and conditions, or NDA, do apply in that case? I've done research on drools documentation, and on jboss and RH website, but couldn't find an answer applying for this case.

Drools Development - documentation and coding of the drools project Theses current two lists will remain and the email address will continue to work for a while. We will attempt to auto-subscribe (i.e. transfer) all existing subscribers. rules-dev people will be subscribed to drools-development. rules-users will be subscribed to both drools-setup and drools-usage - as the current list currently covers both those topics.

Depth in 5x meant rules with the same salience were executed in an arbitrary order, it seems this arbitrary order was not so arbitrary in your case and makes an impact on performance - but as it’s arbitrary the repeatability of this cannot be ensured, even across environments let alone versions. In 6x this is no longer arbitrary, which will allow people more predictability in their rule executions. Load order is also much easier for people to understand and deal with, and often avoids the need to use salience at all - it’s also how people’s brains tend to think. Rules higher up in the file, fire first. We recommend one “agenda-group” per file, so that it’s easy to keep control of those orders. Salience can still over-ride this; but over time we have further ideas to completely remove the need for salience. This didn’t make much sense in 5x as load order was not preserved between kbase updates, so if you add rules later you lose the load order. In 6x we fixed this, so load order is always preserved between versions, an thus adding this enhancement makes sense. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Conflict resolution strategy - before vs after Phreak impl
Conflict resolution strategies are “magic” things, it means how a set of rules behave cannot be determined from reading the rules alone, and could potentially change if someone changes the backend component (possibly without you knowing). Our preference is to ensure any execution behaviour is encoded and visible in the rules themselves. Over time we’d rather create additional declarative ways to do this on the rules themselves, rather than change some magic backend component; such as the experimental declarative agenda we’ve added. CRS in 6x is different to 5x, it’s now choosing the order or rules to evaluate, where as 5x the CRS controls the order in which rules are fired. We need to be free to change these type of things, without worrying about user compatibility - so less we expose to end suers the better; and as mentioned I consider it an anti-pattern in ease of rule authoring and maintenance. The only reason why we haven’t removed all of the implementations is that there is a degree of 5x compatibility in the system still. Phreak is just depth + load order, so it’s not a big change, all it does is remove the degree of arbitrary behaviour you were relying on for performance. Depth in 5x meant rules with the same salience were executed in an arbitrary order, it seems this arbitrary order was not so arbitrary in your case and makes an impact on performance - but as it’s arbitrary the repeatability of this cannot be ensured, even across environments let alone versions. In 6x this is no longer arbitrary, which will allow people more predictability in their rule executions. Load order is also much easier for people to understand and deal with, and often avoids the need to use salience at all - it’s also how people’s brains tend to think. Rules higher up in the file, fire first. We recommend one “agenda-group” per file, so that it’s easy to keep control of those orders. Salience can still over-ride this; but over time we have further ideas to completely remove the need for salience. This didn’t make much sense in 5x as load order was not preserved between kbase updates, so if you add rules later you lose the load order. In 6x we fixed this, so load order is always preserved between versions, an thus adding this enhancement makes sense. So the key takeaway is for future systems it should make them easier to author and with more predictable performance results. You can still run the rete engine if you want, it’s available through configuration. Although it would be better to start working with Phreak, so you can provide feedback to us, for future improvements. Mark On 28 Jul 2014, at 16:31, mikerod mjr4...@gmail.com wrote: In version 5.x of Drools I see that it offered configurable conflict resolver strategies. I also read a few different Drools documentation sources that discussed varieties of complex conflict resolution strategies. One source discussed a tiered implementation by the name of CompositeConflictResolver - which was @ http://legacy.drools.codehaus.org/Conflict+Resolution. We have been experimenting with uplifting from Drools v5.6.0.Final to a v6.x version and we noted a fairly significant performance degradation /(a)/. When digging into some rule logging, we found that the issue was that our rule load order was not behaving well in terms of conflict resolution. The wrong rule activations were chosen to go first on the agenda, and this was causing a lot of unnecessary/redundant movement within the Rete network. After reading through the documentation on conflict resolution strategies and noting that it was configurable in Drools v5.x, I started thinking more about the importance a conflict resolution strategy on performance. Digging deeper, I believe Drools v5.6.0.Final uses `org.drools.core.conflict.DepthConflictResolver` as the default resolver (which is not the CompositeConflictResolver mentioned above interestingly). In Drools v6.x (around v6.2.x I believe) with Phreak enabled, there is a `org.drools.core.conflict.PhreakConflictResolver` that is used as the default resolver. This raises a few questions: /1)/ With Phreak enabled, it looks like the conflict resolver is *not* configurable anymore. I believe this is the case due to these lines https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/java/org/drools/core/common/AgendaGroupQueueImpl.java#L68 . Why was this configuration options removed? /2)/ The PhreakConflictResolver does not seem to be doing anything very sophisticated now. I gather that it respects salience first, then falls back to rule load order. I found this around these lines https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/java/org/drools/core/conflict/PhreakConflictResolver.java#L52 . Why was this implementation chosen? Is it discussed or documented anywhere? Was it determined that this performs better than anything else or that there

Then also create a separate google group for those wanting help on writing rule applications, that’s authoring (drl, score cards, decision tables etc) and running (insert, fireAllRules etc); this would become a deep knowledge area. In the google group you would not ask how to install the workbench, or how to deploy your app, or how to setup HA etc. Thoughts? We are about to do 6.1 final.

I see the rule fire as expected, printing out the message 3 seconds after
the event is added into the session. While the event is waiting, I see a
FactCount of 1 in the session. After the rule fires, the fact count goes
to 0. However, using JVisualVm, querying the heap dump shows 1 instance of
MyEvent, referenced by an EventFactHandle and several other Drools objects.
Is this a bug, or is there a better way to write this rule so Drools’
internals let go of the object after it is no longer a fact?

Re: [rules-users] Equality semantics of logical assertions and stated assertions
The TMS tracks the number of supporting rules for a given fact. When you insert something you are typically calling “new”, which always means a new identity. If this was done by identity every local insertion would be a different object, and thus only ever one supporting rule. So the most common use case for this is with equality. Where as the most common use case for normal working memory is identity. We made the working memory identity/equality configurable, as it works the same with the same API. The use case for identity with the TMS is less common, but would not be impossible to support, but it may require an alternative api, for it to make sense. It’s not been done, as no one has asked for it before. Mark On 27 Jun 2014, at 17:16, mikerod mjr4...@gmail.com wrote: I understand that logical insertions in Drools does not insert two facts that are equal according to their #equals implementation (and associated #hashCode logic). I'm basing this off of my own investigation plus the (well written) documentation @ http://docs.jboss.org/drools/release/5.2.0.Final/drools-expert-docs/html/ch03.html. However, normal/stated fact assertions only use identity-based equality checks - by default. It looks like this can be changed to value-based equality via RuleBaseConfiguration. I have found some related, old Jiras: https://issues.jboss.org/browse/JBRULES-266 https://issues.jboss.org/browse/JBRULES-233 In both cases, Mark Proctor had a final remark, but I wasn't able to understand what was really decided and why. One specific comment @ https://issues.jboss.org/browse/JBRULES-266 is, logical assertions are always equality based. Stated facts can now use identity and equality - using your configuration settings. I have added another configuration setting to dictate how logical over-ride works. Does it discard the original fact, or turn it into two stated fact handles. What is the reasoning behind only using the value-based equality for logical assertions? Why is it not configurable as stated fact assertions are? Also, why is the default behavior of stated fact assertion to be identity-based equality? - I find the inconsistency between the default for normal assertions and the (only option) for logical assertion to be a bit confusing/inconsistent. I'm just looking for an understanding the motivation behind these design decisions. I have had a lot of performance issues using, primarily, logical assertions due to the no duplicate checking being done. Even the stated assertions do still come with a cost of creating the initial FactHandle. With deeply nested/complex domain objects, the #equals and #hashCode implementations may be quite expensive when executed many times throughout rule execution. This is especially prominent in accumulators that may later accumulate these objects into collections that then are also subject to this equals/hashCode penalty. I have a related post a while back @ http://drools.46999.n3.nabble.com/Object-size-impact-on-session-insertion-performance-td4028244.html. I do not believe it is typical to use complex domain model objects as the keys to something like a HashMap. One reason (there are more; especially for mutable objects) would be due to the performance around having them be hashed and equality checked regularly when the map is accessed, modified, etc. The creation of many FactHandle's has shown up in some of my profiling performance problems due to this the constructor immediately hashing my domain model objects. I think the reason the fact handles use this information is for value-based equality comparisons - such as the only method used by the Truth Maintenance System logical assertions. I would really appreciate more insight into the motivation for not allowing #equals facts to be logically asserted separately into working memory - especially since there is a price to pay for the behavior in my case. -- View this message in context: http://drools.46999.n3.nabble.com/Equality-semantics-of-logical-assertions-and-stated-assertions-tp4030179.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 ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] kbase using kie
Do you really need kie-ci? If not remove it. It’s not needed, unless you want maven to resolve dependencies and handle the update process, which you do not. If you cannot figure out the api, then the alternative route is to simple call the mvn plugin via the command line, each time you detect a file change. The downside here is it’s heavy as you are not taking advantage of the incremental builder.

Davide is correct, for our analysis to work, the constraint must not be inside
an eval, and any constraint that does not start with a field name is internally
rewritten as an eval.

I think I know what is happening here.
I assume your supportFT class is @propertyReactive.
(btw, you should follow bean conventions and capitalize class names)
Looking at Rule 1, you don't set the value directly, but you do it through
a modify. Your rule 2, which checks for the value, uses the function
containsAny
rather than the field direclty as in value IN (..).
At the moment, the engine has no way to realize that the function
involves the field value - I'm not even sure it is possible in general -
Property reactivity will ignore the update since, from its perspective, none
of the fields relevant to the rule has been affected, hence rule 2 will
not hit.
If you use eval in the constraint, property reactivity is disabled, so
the rule
WILL fire the first time, but now you are vulnerable to infinite loops,
as if
you did not have propertyreactive.
You may have to use the @watch() annotation explicitly to control which
modifies will cause reevaluations and which ones won't (see the manual
for this)
Adding eval everywhere is not a good idea.

in this example I can add eval, because the Fact Types model is different,

Re: [rules-users] Are there second-rate fact types?
The feature was more important when we didn’t allow casting, but people still
wanted to work with Maps and Lists.
Map( this[key].age 30)
Collections where defaulted to typefalse(false)
Now that we support inline casts, it can be argued that things should always be
type safe:
Map( this[key]#Person.age 30 )
It’s hard to change this now, without breaking backwards compatability.
The docs don’t say that it’s defaulted to false for collections, only that it’s
useful for Collections. Someone want to submit a pull request fix for this?
4.7.2.1.2. @typesafe( boolean )
By default all type declarations are compiled with type safety enabled;
@typesafe( false ) provides a means to override this behaviour by permitting a
fall-back, to type unsafe evaluation where all constraints are generated as
MVEL constraints and executed dynamically. This can be important when dealing
with collections that do not have any generics or mixed type collections.
4.7.5. Non Typesafe Classes
@typesafe( boolean) has been added to type declarations. By default all type
declarations are compiled with type safety enabled; @typesafe( false ) provides

https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test/java/org/drools/compiler/integrationtests/IncrementalCompilationTest.java#L158
Here is the method to add a rule, once the KieSession is created and
configured:
public void addRule(String rule){
KieServices ks= KieServices.Factory.get();
ReleaseId rid= ks.newReleaseId(org.kie, businessrules,
1.0);
KieFileSystem kfs = ks.newKieFileSystem();
kfs.generateAndWritePomXML(rid);
kfs.write(src/main/resources/rule.drl,rule);
KieBuilder kb = ks.newKieBuilder(kfs).buildAll();
if( kb.getResults().hasMessages(
org.kie.api.builder.Message.Level.ERROR )
) {
for( org.kie.api.builder.Message result :
kb.getResults().getMessages() )
{
System.err.println(result.getText());
}
}
InternalKieModule kieModule = (InternalKieModule)
ks.getRepository()
.getKieModule(rid);
byte[] jar = kieModule.getBytes();
Resource jarRes = ks.getResources().newByteArrayResource(jar);
ks.getRepository().addKieModule(jarRes);
kieContainer.updateToVersion(rid);
}
But when I'm calling this method, I get the error below:
java.lang.NullPointerException

For the line : kieContainer.updateToVersion(rid);
But if I'm firing the rules once (kieSession.fireAllRules();) before adding
the new rule, I don't get the exception O_o
Someone has any idea why ?
thanks!

Re: [rules-users] Drools slowness in first calls

Even if the kbase is loaded, we need to make some fictive calls (fire the rules with some facts) until it begins to respond within a reasonable time. It's like we need to warm it up..

Re: [rules-users] Does generated graph rules is build to respect a disjunctive normal form ?
I thought clips did do disjunction normal form? in that all ‘or’s are removed from the body of the tree and moved to the root, thus rewriting the logic into separate rules?

Re: [rules-users] Abstraction between rules and data model?
On 2 Jun 2014, at 13:59, Horváth Péter Gergely h.pe...@mailbox.hu wrote:
Hi Davide,
Thanks, I just wanted to get a grasp of the time frame we could expect
(whether it is a month or half a year etc.) :)
We haven’t had much feedback on traits, and the system is still in flux. So we
cannot give any time frame. At some point there will be a momentum in the
number of users, that will allow us to have a degree of confidence in it, but
at the moment we’ve had close to zero feedback from users on this functionality.
But there is nothing to stop you using this now. The only difference is that we
may or may not change it up until the point we call it “non-experimtal”. It
won’t make any difference to the execution stability and bugs.
A bit more about our use case: we have a massive old system, with basically
all of the logic embedded into Java. We are in the process of refactoring and
moving up-to-date Java technologies. We would like to introduce a rule engine
so as to extract logic from the core of the application. Since we need to
re-structure the whole back-end and persistence layer, we face a challenge
with rules: as the object model changes, the rules have to change also, which
simply would not be manageable. (Imagine something really crazy/complex here:
6-8-... levels of object hierarchy, grown most of the time organically during
the last 15 years.) Deferring the introduction of the rule engine until the
data model classes reach the final, ideal state is not something we can now
afford, the rule engine and data model refactoring projects should be done in
parallel, without the one paralyzing the other one...
Take the following as an example (from the manual). Say, you have Applicant
class, with age and name fields:
public class Applicant {
private String name;
private int age;
// getters/setters
}
Then, you could have a simple rule, requiring, that name must be supplied:
rule Supplied a proper name
when
Applicant( name == null)
$a : Application()
then
output.println(### RULE MATCH: Invalid application: No name specified!);
$a.setValid( false );
end
But there is an issue: every single time you refactor / rename any field in
your domain model, the rules are no longer valid. That is why we have a
problem: we should start developing rules against a relatively fluid object
model. Say Applicant.name is renamed to Applicant.fullName, then the existing
rules are no longer valid. That is why I would like to have some sort of
abstraction, since the rules do not really need to know the exact details of
the underlying class.
As a demonstration of my idea, I managed to hack together a custom
parameterizable operator, that calls the method where the annotation contains
the same parameter as in the rule. With this approach, changes to the field
names would no longer affect the rules. Again, I have to highlight, I don't
think this should necessarily be implemented in the core engine. What I am
looking for is some kind of extension point allowing us to hook into the
expression evaluation part of Drools. (Instead of a custom operator,
something, where we can access the object and the expression being resolved
so that we can implement our custom logic for returning the value of the
expression)
The rule now looks like this - note the custom satisfiesRule operation. The
Name of this Applicant expression now abstracts away the name of the actual
field (the second parameter is the operator for the test, please ignore it
for now):
rule Supplied a proper name
agenda-group evaluate-application
auto-focus true
when
Applicant( this satisfiesRule[ Name of this Applicant , is equal to
] null )
$a : Application()
then
output.println(### RULE MATCH: Invalid application: No name specified!);
$a.setValid( false );
end
The name is simply mapped by a custom annotation:
public class Applicant {
private String name;
private int age;
@MyBusinessExpression(Name of this Applicant)
public String getName() {
return name;
}
// getters/setters
}
I think having a level of abstraction between the rules and the data model
would not only be useful for de-coupling, but also can make rule authoring
easier for the business users. The custom operator (please see attachment) is
a kind of hacky workaround, but demonstrates how something similar could be
achieved at run time (without using DSL or any other rule transformation).
Please let me know what you think. :)
Cheers,
Peter

Creating a custom build of Guvnor sounds to require quite some effort, I'm not sure whether we should go down that way. Unfortunately, I don't think we will have the option to use Maven based rule deployments at all. In Drools 6, KieScanner seems to be built around Maven; this doesn't suit environments where the application runs on servers without Maven (e.g. no Maven installed, no local Maven repository allowed, access to remote Maven repositories blocked by firewall.) maven is just a JAR like any other JAR. And a Maven repo is just a file system. If you write something or use something else, it’s just going to be creating equivalents. Do you see any way for us to load rule files directly from the file system and still have the automatic change detection? Use the maven plugin. You don’t need to be maven enterprise to use maven.

Re: [rules-users] Using git-p4 with workbench
We use JGit and I don’t believe (but could be wrong) it has direct p4 support, like this git extension offers. http://git-scm.com/docs/git-p4 However Git is distributed, so just clone and sync a p4 repo with this Git command line tool and use it as an intermediary. Then merge/mirror this intermediary with our JGit repo.

Re: [rules-users] Anyone want to help on our new Rule Algorithm?
A first good topic, now that we build and propagate tuple sets, is can we parallelism our joins? Look at the insert loop, on line 94. So it iterates and builds a resulting tuple set, which is eventually propagated. Can that set be built in parallel? https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/java/org/drools/core/phreak/PhreakJoinNode.java The key aspect is the iterator right memory. While that memory may or may not be indexed, it always returns a list. In the case of indexing, the list will sublist for that overall memory. Ideally those lists will be adaptive, only turning on parallel iteration when appropriate (enough joins), while trying to avoid any additional cost when parallel iteration is not used. Note currently all lists, are liked lists - we do not use arrays. Once that works, the other methods, right insert, update and delete can all be parallelized.

Re: [rules-users] Drools 6.0.0 activation-group + salience bug or feature?
That’s what an activation-group does. The first rule (with the highest
salience) fires, the others are cancelled.
Out of interest, what’s the game? Something online we can look at? I have an
interest in games development for Drools, and have been slowly adding examples.
Space invaders was my latest one:

Re: [rules-users] Rules not picked when packaged inside the JAR
This may be a container issue, which container are you using? It doesn’t locate resources via the classloader. Instead it locates the jar on the file system and scans the contents of the jar. The jar must have a kmodule.xml file inside of it to be recognised and it’s resources added. We know this works for normal jars. Inside of JBoss EAP you need to add the JBoss VFS jar (I think).

But, the package names are not being injected into the knowledge base when it

If I define the package names and hard-code them into the packages property

Could you please let me know if there is a way to make the package names

when the knowledge bases are setup and I am trying not to hard-code these.

Hello,
I want to ask you if it is a good practive to pool stateful sessions
for a specific ruleset to improve the execution performance.
Actually in my application I execute my rules by calling SOAP
webservice. For performance purpose, I test multithreaded calls to my
webservice and I noted that when I pool sessions in the server side,
it improves the performance a lot.
To pool sessions, I just declare multiple ksession tag in my
kmodule.xml :
kbase name=KBase packages=com.example.*
ksession name=KSession1/
ksession name=KSession2/
ksession name=KSession3/
ksession name=KSession4/
ksession name=KSession5/
/kbase
In my spring webservice endpoint I just put that code to handle the
pool :
@Endpoint
public class ExampleEndpoint implements InitializingBean {
@Autowired
private ExampleRuleService ruleService;
private MapInteger, Boolean isRunningMap = new
HashMapInteger, Boolean();
private static final int NB_POOL_SESSIONS = 5;
@PayloadRoot(localPart = com.example.ExampleRequest)
@ResponsePayload
public ExampleResponse handleRequest(
@RequestPayload ExampleRequest request) throws
InterruptedException {
KieServices ks = KieServices.Factory.get();
KieContainer kc = ks.getKieClasspathContainer();
while (true) {
for (int i = 0; i NB_POOL_SESSIONS; i++) {
boolean run = false;
synchronized (isRunningMap) {
if (!isRunningMap.get(i)) {
isRunningMap.put(i, true);
run = true;
}
}
if (run) {
KieSession ksession = kc.newKieSession(KSession
+ (i + 1));
ExampleResponse response =
ruleService.run(ksession, request);
ksession.dispose();
isRunningMap.put(i, false);
return response;
}
}
Thread.sleep(100);
}
}
public void afterPropertiesSet() throws Exception {
for (int i = 1; i = NB_POOL_SESSIONS; i++) {
isRunningMap.put((i - 1), false);
}
}
}
It works well because in my benchmark I improve 5 times the
performance (as I have 5 different threads) but I wondered if it is a
good practice and if it does not hide any issues that I could have in
the future.
Thanks for your help.

Phreaks algorithm use multi threading according to use 'from

I did not get the idea behind it. Why don't you use new to create new instances. Then the bundles have to define their dependencies very carefully to become compiled. At the point where you see Class.forName it means the implementation is not on the class path of that module, but the interface is. So the provider pattern mechanism uses reflection to load the instance to return to you under the targeted interface. This is how all our factories work, we have all the api in -api but none of the implementation. It binds the implementation at runtime, via reflection. However, in the case of our -api factories, we already address this in OSGi by using Activator injection. My question is about the architecture changes to meet OSGi requirements. There are a lot of Class#forName calls to create new instances. In OSGi it is not that easy then in java SE. Each bundle has its own class loader. And classes are only visible to bundles, if their package was imported. We have not done a full audit of Class.forName. I should add that loadClass itself has problems too, related to serialisation - which is why we use forName. If you want to do an audit and submit via a pull request alternatives, then please do. Although remember not all those forNames (in the case of our factories) will b used by OSGi, so make sure you find ones that you believe are actually a problem. We also did work around making sure all our jars have unique package names, to avoid split packages. And there was a lot of work around repacking our dependencies. So my question is, whether that approach is the suggested way to add Drools and JBPM to OSGi containers. Sorry I don’t understand the question fully. The classloader argument, is if you need to specify parent classloader. There are a variety of use cases for this, such as if people are doing runtime code generation on custom classloaders that they want to make visible to Drools. My understanding is that drools now works on karaf. Maybe try one of our latest builds if there any issues, then come back and let us know. http://downloads.jboss.org/drools/release/snapshot/master/ Mark On 2 Apr 2014, at 20:51, Florian Pirchner florian.pirch...@gmail.com wrote: Hi Mark, could not find anybody in cc :D Good to hear, that there is progress in the OSGi stuff.

Each bundle has its own class loader. And classes are only visible to bundles, if their package was imported. I could see, that there is a ProjectClassLoader. And that there is a way to provide a common parent classloader. That might be the bundle classloader. So most of the classes can be found by Class#forName. But it requires a bundle, that imports all the dependencies from drools, kie and jbpm. Only in that case, the bundles are visible to the bundles class loader. So my question is, whether that approach is the suggested way to add Drools and JBPM to OSGi containers. But a drawback is, that there is no real support about required dependencies during development. Except the drools bundles will define their imported packages very carefully. Why do you use Class#forName to load classes? I did not get the idea behind it. Why don't you use new to create new instances. Then the bundles have to define their dependencies very carefully to become compiled. Thanks a lot for your answers.

However not all modules are migrated, as it’s a work in progress. I don’t know which currently are or are not, I’m cc’ing in the developer behind this to answer.

But it seems there are some issues that do not allow to run drools 6 (and jbpm) under OSGi properly. For instance: JPAKnowledgeService .newStatefulKnowledgeSession(kieBase, null, env); will never find org.drools.persistence.jpa.KnowledgeStoreServiceImpl since it is not in the scope of the current ClassLoader. Tried to tie things up, but then there would be a cyclic dependency between kie-internal and jbpm-persistence-jpa. I also could see, that a ProjectClassLoader was added. I found a way to put my current BundleClassLoader as its parent into play. This solves a lot of class loading issues. For me it seems, that Drools 6 was not designed to run in an OSGi container. Is there ongoing work to integrate Drools and JBPM Version 6.x into OSGi environments properly? -- Thanks for your answer Florian Pirchner ___ rules-users mailing list rules

Re: [rules-users] Memory leak due CompositeClassLoader
There were a lot of fixes around this and other areas. Please upgrade to 5.6, then come back if you have problems. Mark On 1 Apr 2014, at 14:24, Romain Thouvenin romain.thouve...@amadeus.com wrote: Hello, I am working on a Web application that uses a third-party component that uses Drools 5.2.1 (I know this is old, but this is not my choice). While investigating memory leaks in my application, I found out that after redeploying the webapp in the application server (Weblogic), the leaking class loader is referenced by: org.drools.util.CompositeClassLoader.classLoaders This is because when that class is instantiated by org.drools.util.ClassLoaderUtil, the initial list of class loaders includes the context class loader of the current thread, which is the class loader of my webapp. But the class loader of CompositeClassLoader is not the same as my webapp, so when I redeploy my webapp CompositeClassLoader continues to exist and keep that reference to the webapp class loader, which is therefore never garbage-collected. Browsing a bit through the code, I see no reference to CompositeClassLoader.removeClassLoader that could remove the faulty reference. So my questions are: 1) Is my investigation correct? 2) I found this thread on the list: http://drools.46999.n3.nabble.com/permgen-leak-td4027038i20.html Is this the same issue as mine, meaning that it is fixed in 5.6.0 and 6.0? If yes, pushing this third-party component to upgrade is really the only solution I have? I am not at all a knowledgeable user of drools, I just happen to be user of that third-party component, that is why I wanted confirmation of my findings. Thanks for your help!

Re: [rules-users] Drools Fusion inconsistencies at increasing event throughputs
We have this fixed now. Hopefully this will be in the nightly build, and available for testing tomorrow. I’ll ping with a link to the nightly builds once it’s available.

Still, have you tried my first example (using the cron directly to the counting rule)? Can you confirm it is not working, since this was my first concern? As I said in the previous post, using the CronTrigger pattern greatly improves stability (I managed to run it at 500 eps), but it is not resolutive. Adding a few rules, it's enough to go back to instability. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- Vieri Emiliani ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
