Re: [rules-users] drools design question
You could hold them all in a single KnowledgeBase with State, FactorY and FactorX as Facts themselves checked in the Rules' RHS. You could still have multiple DRL files (to aid authoring and maintenance) but load them all at once. The RETE network shares nodes for patterns shared across multiple rules. If your DRLs therefore share RHS patterns (e.g. simplistically State XX premium for criteria A = 100, State YY premium for criteria A = 110) the criteria patterns will be shared.

Re: [rules-users] drools design question
I'd definitely suggest this approach. Compiling DRL files into a knowledge base is very expensive and something you want to avoid doing as much as possible and probably wouldn't come anywhere close to meeting your performance requirements!

Yes, but it's not a full blown leak. Wrapping stream use in a

There may be other instances.

Date: Wednesday, March 16, 2011, 11:49 AM
I am running Drools (actually JBoss
Rules 5.1.0 ) in Glassfish.
My deployable is an EJB that uses a
StatelessKnowledgeSession to run
some rules that I get from a KnowledgeAgent that
has a
Changeset with a
.drl in it.
Therefore, I have placed the drools compiler into
the
deployable and it
all appears to work.
Glassfish has a clever little mechanism that, when
you
unload a
deployable that had some open streams, it tells
you all
about it (and
kindly closes them).
Glassfish is reporting that InputStreams are being
left
open that were
opened in the isPackage() method of
org.drools.commons.jci.compilers.EclipseJavaCompiler.
That method has the following code in it:-
final InputStream is =
pClassLoader.getResourceAsStream(ClassUtils.convertClassToResourcePath(pClazzName));
if (is != null) {
return false;
}
So, when is is not null (i.e. open), it is
forgotten
about and not closed.
Isn't this a potential file handle leak?

[rules-users] Migrate from JBRMS 4.0.7 to Guvnor 5.1
Hello all
I need to migrate from 4.0.7 drools to 5.1, could you please give some
advices and links?
We have drools JBRMS 4.0.7 app with lots of rules, persisted in Oracle. We
haven't any .drl files for these rules. I've tried to export these rules via
export feature from JBRMS 4 and then import the derived XML via import
feature in Guvnor 5, but I get the following error:
17:56:55,365 INFO [STDOUT] ERROR 16-03 17:56:55,361

Is there some way how we can transfer the rules from JBRMS to Guvnor? Does
the Guvnor has another rules format, so it can't import from JBRMS XML? Is
there some specs about differences, so I would be able to write the
converter? Or is there some already published converter?
Would it make sense to export the rules via JCR API from old JBRM JCR (1.3)
and then import it to new JCR repo created by Guvnor?
How we can upgrade the drools version without loosing our already created
rules?

I know there are ways to force the event to be expired but I’m looking for a solution that doesn’t involve to write new rules. For example, I’m using this kind of solution: declare A @role( event ) @expires( 1h ) end rule internal - expiring A timer(int:1h) when $a : A() from entry-point incoming then retract($a); end Although this solution works (from Drools 5.1), I’m forced to write a rule to expire an event that’s supposed to be expired initially. There’s a simpler way to do this? I’m thinking correctly? Once again, thanks!

Re: [rules-users] drools design question
Thanks everyone for your inputs Yes, so the confusion that I have is, with loading multiple drls. If I load all the drls in memory(may be 100s), does it mean that when I say fireallRules, it is going to run the rules from all the drls?? That is what I don't want. For a particular session at runtime, I may need to run drls from just some specific drls and not all the drls. How can I tackle this If I load all the drls?

Re: [rules-users] Custom dates with @date-effective and @date-expires
Thanks for the answer. Yes, it may be easier to achieve with simple date fact
but we have thousands of rules and each and every one of them has this temporal
requirement. I was thinking along the lines of SessionClock. I know there is a
'realtime' and 'pseudoclock' implementation of it. May be I can write my own
implementation of SessionClock and set any arbitrary date passed by the user
into the knowledge session config. Then the rules attributes (@date-effective
and @date-expires) can take care of filtering out the ones not effective on the
date that I am setting in SessionClock. Am I thinking in the wrong direction?

Hi,

context of @date-effective and @date-expires metadata that can be specified

metadata uses current date though I am not clear what current date (system

You lost me. Why are you defining a rule to retract your event? If you are running in STREAM mode, @expires will take care of the retraction for you automatically...

Re: [rules-users] drools design question
Actually what you want is that only the rules from the DRLs that you want are activated and their consequences run (a subtle but important distinction). Put another way it doesn't matter how many rules are in the knowledge base and evaluated as long as only the rules you want are matched. There are two main approaches you could do to control this. The first is to use agenda groups with rules in different DRLs being in different agenda groups, this then lets you control which groups consequences are run and in what order to. Another approach is to introduce some additional facts into the working memory - EnabledRuleGroup(String groupName). The first condition in each rule would then be the statement exists EnabledRuleGroup(name ==myDlrFilenameXYZ) Then only rules matching the statement would be evaluated. There are probably other variations around this too - things like agenda filters to filter out the activations you don't want.

Re: [rules-users] drools design question
Don't forget Facts are matched as they are inserted into WorkingMemory too. fireallRules() only executes the resulting activations on the agenda - that as Thomas states can be controlled by a number of means.

Yes, but I just fired up a small project using it and it used 100% of CPU. If you build the attached project you'll see the tests run just fine. (They use fireAllRules.) If you launch from the commandline, (java -jar target/DroolsBoxes-1.0.jar) which uses fireUntilHalt, the rules fire (and complete) just fine, but it continues to use 100% of a cpu core indefinitely. This is with 5.1.1. If I change the drools version to 5.2.0-SNAPSHOT it compiles but the tests won't run.

[rules-users] Limiting rule evaluation--not firing
Hello; I am aware of the fundamental difference between inserting facts--and evaluating them against all the rules in the rule base--and firing rules--i.e., executing only certain rules' consequences. I understand that ruleflow-group and agenda-group and activation-group can all be employed to govern which rules' consequences are fired at fireAllRules() time. My question (which has been asked by many others in different ways, yet not answered as far as I can tell on the mailing list to anyone's satisfaction) is: is there any construct that can be used when it is known up front that only certain rules will match? That is, is there any way to limit rule evaluation? For example, I have a series of surveys that all use the same KnowledgeBase to govern the flow of the user through the survey. But once I've asked a given question, then I know right then and there which rules have a chance of taking effect. I've already put them in their own agenda-group, and I already switch focus to that agenda group prior to fact insertion, so that by the time I call fireAllRules() I've made it so that--say--ten rules' consequences are the only ones (out of hundreds) that could possibly fire in this given session. But unless I'm radically misunderstanding something, each time I insert a fact, it is evaluated against all the hundreds of rules, even when several hundred of those rules don't have any chance of having their consequences firing. I even understand (I think) why this is. If I were, for example, to subsequently pop the agenda group that I had set focus to, then MAIN would be selected, and for those activations to fire the inserted fact would have had to have been evaluated against all the rules, including those whose agenda group is MAIN. But I guess what I'm wondering is: can I somehow turn this off? Can I, in other words, partition the KnowledgeBase itself? Can I effectively tell Drools, during this stateless session, don't even bother trying to match facts against rules 1-10, just try rules 11-14?

I've noticed that the LHS of the Eclipse Guided Rule Editor can employ DSL sentences or an object model, but there doesn't seem to be a manner to incorporate the DSL on the RHS of rules (other in free form code) Is that by design?
