Re: [rules-users] How to figure out the recent node(s) in a drools flow ?
Excuse me, I think that I haven't been clear enough. The drools-bam module doesn't force you to activate the persistence. That's two differents things in fact. From what I've understood of the execution mechanism of drools, by default, it doesn't write anything in any database, so, if you want to have the recent node state of a flow from oustide the program that executes the flow, you have to write into a database, I can't figure out any other solutions... Drools-bam module creates two really simple tables that's named by default processinstancelog and nodeinstancelog. So it's really easy to request in those. That's the only way I can find out for your matter. By the way drools-bam can be found in the maven jboss repository (version 5.1.0-M1). If you find out any other solution, please tell me, I'm interested. -Message d'origine- De : robert.weissm...@web.de [mailto:robert.weissm...@web.de] Envoyé : mercredi 26 mai 2010 22:30 À : Rules Users List; PAYET, Manuel Objet : Re: [rules-users] How to figure out the recent node(s) in a drools flow ? Hm, for the event-listener way I need to have an App up and running to catch those, but what about an App which will be turned on later, but needs to know the actuall state of the process. This leaves only the first possibility, to use the persistence mechanism and check out the database ? That sounds pretty strange to me, since the mechanism to continue from the actual (last actual) state of the process must be there already (or is this not possible with the drools flow ? ) and therefor I was hoping to get direct API-access to this mechanism. So please, let me know if the DB is the only way to figure out at which recent state (which nodes are recently active) the process instance is or if there is some API to get this information directly.

On 26/05/2010 09:56, paulnnosh wrote: Hi Chaps, We currently use Jrules 5 and are looking at our options going forward. We are going to evaluate Drools alongside some other products. So far I like the look of Drools but there are a couple of things that are puzzling me... - In our Jrules implementation our BOM/XOM exposes some of our application logic so that our rules can access application code and services to make decisions and updates where necessary. I can't see how this is possible in Drools. Pojos just work out of the box, it's much simpler :) So any inserted object is a pojo and is a direct reference to the object the user inserted. Use globals (also simple pojos) for registering and accessing services. - Our ruleflows use decision tables to define which rules will run dependant upon the transaction type received. This makes assigning a rule to a single ruleflow group inappropriate as one rule could be used by many different transactions. Is it possible to create an ArrayList of rules and execute them one at a time via ruleflow action node? JRules ruleflow and Drools ruleflow are very different. In JRules each ruleflow group is a separate knowledge base and executes statelessly. Where as RuleFlow in drools is for a single knowledge base and stateful sessions. You can simulate the more traditional ilog way by using Drools Flow, and create a work item to execute some input vars against a stateless session. This way each branch can have it's own knowledge base and copy of relevant rules.

Also, around Guvnor, our intention is to make this usable for business analyst and subject matter experts, i.e. they should be able to configure the rules and test them as well. Our understanding is that Guvnor and DSL are the options. At this point, to us, DSL seems like a better option than Guvnor from business analyst perspective. We are currently unable to build even slightly complex scenario and their corresponding test scenarios in Guvnor. So we were wondering if others in this forum are also reverting to DSL in case they want to get BA involved.

Re: [rules-users] Moving from Jrules to Drools a couple of Issues
I Just need clarification on the injection of POJOs to give access to application services etc... I understand the fact that POJOs inserted into the working memory are direct references to the actual objects inserted by the calling application, that's great. However, currently in Jrules (sorry to keep telling you what we have already!) a number of our functions make regualr use of a large number of our core application classes. To have to insert all of these each time a ruleset is called would soon become unwieldy and I have concerns about the amount of working memory that would be required. Is it possible to create a reference to my application and initilise this at the start up of the server so that these classes are available to my packages without having to load them into WM each time? Many Thanks -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Moving-from-Jrules-to-Drools-a-couple-of-Issues-tp844379p847769.html Sent from the Drools - User 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] [Drools Fusion] Can't detect 2 occurrences with sliding window
Hello again,
I'm back on my problem and a colleague of mime suggested me the following
rule instead :
# declare events
declare Operation
@role(event)
@timestamp(date)
end
rule overActivity
dialect mvel
when
#condition : 2 operation in less than 1 minute
* $operation1 : Operation($ipAddress1 : ipAddress) **
from entry-point OperationStream
$operation2 : Operation(this != $operation1, ipAddress ==
$ipAddress1,
this after[ 0s,30s ] $operation1) from entry-point
OperationStream*
then
#actions
System.out.println(over-active user + $ipAddress1 );
end
It works, and the main difference is the use of *after[]* instead of *
window:time()*
Is it because the window:time() was used outside of an *accumulate()*function ?
I'd just like to understand this.
If anyone can take a few minutes to answer, thank you in advance
Best regards,
Xavier

Re: [rules-users] [Drools Fusion] Can't detect 2 occurrences with sliding window
Hello Edson,
Ok, it's clear now.
I'll try my first attempt with the new 5.1M2 version.
Thank you very much !
Best regards,
Xavier
2010/5/27 Edson Tirelli tire...@post.com
Xavier (and others),
First, let me explain the problem: the temporal distance algorithm in
5.0.1 was not taking sliding windows into consideration when calculating the
expiration offset for the objects. So, even declaring a 60s sliding window,
the engine thought your expiration offset was 0s, and was expiring them
right away. When using after, then engine correctly evaluates the
expiration offset and the problem does not happen.
There was a workaround (although for your case using after IMO) that
is to explicit declare an expiration offset:
declare Operation
@role(event)
@timestamp(date)
@expires( 60s )
end
This is fixed in 5.1M2 and now the engine does take sliding windows
into consideration.
In your case, though, using temporal operators like after is probably
semantically better. Sliding windows are useful when used with
accumulate/collect. For instance, if you want to count how many operations
the user did in the last 60 seconds:
Number( $count : intValue ) from accumulate(
Operation() from entry-point OperationStream,
count(1) )
Sorry for the late answer... I was offline during the last couple
weeks.
Wolfgang, loved your new terminology: pseudo-too-old, pseudo-too-late.
:)

[rules-users] Activation-group does not work when using a Stateless Session with Sequential Mode enabled
We spent some time trying to figure out why our activation-group functionality was not working. Activation groups are supposed to cause only a single rule to fire within the same group. What we were experiencing is that all the rules were firing, essentially ignoring the activation-group setting. We have determined that it is because we were setting an option on the KnowledgeBaseConfiguration of Sequential.Yes. If we comment out that line activation-groups work. I don't know enough to know if this is by design or if it is a bug. I searched the documentation and the drools-user Nabble forum and could not find an answer to this issue. I wanted to at least post this information so that if anyone else has this problem they don't have to go through the same struggle we had. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Activation-group-does-not-work-when-using-a-Stateless-Session-with-Sequential-Mode-enabled-tp849037p849037.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
