[rules-users] How to use GlobalArea enum inside package defined rules
Hi,
Would like to use GlobalArea enumeration - 'Member.title': ['Mr.',
'Miss']
in my custom package rule. Am trying to access it in DSL rule (as we want
guided editor to use enum), like {title:ENUM:Member.title}
If I create above enum in custom package, am able to do it cleanly.
Also tried using --- {title:ENUM:GlobalArea.Member.title} , but it didnt
work.
Need help on how to access the global area enum, as we need to use the same
across many packages.
Regards, Pravin

Re: [rules-users] How to use GlobalArea enum inside package defined rules
AFAIK, you still need to import the asset from the Global Aarea into your
package.
Think of it like creating a symlink\shortcut between the Global Area and
your package - changes to the asset in the Global Area will be visible in
your package.
Assets in the Global Area are not automatically visible to all packages.

[rules-users] Validation flow - defer expression evaluation
Hi, I was wondering which is the proper way to do sanity checks (not null etc...) on a fact before starting the actual business rules. I have created a a ruleflow with a validation node (VALRFG) and a business rule node (BRRFG) to determine execution order. If in the validation node a not null constraint is violated, the session is aborted (drools.halt()). Problem with this approach is that assertions defined in rules of the ruleflow-group BRRFG are validated before the validation rules execute. The engine throws exception at org.drools.rule.PredicateConstraint.isAllowed(PredicateConstraint.java:298) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:130). ... at org.drools.base.mvel.MVELPredicateExpression.evaluate(MVELPredicateExpression.java:101) at org.drools.rule.PredicateConstraint.isAllowed(PredicateConstraint.java:291) How can I make sure that the validation rules are executed before the mvel expressions in the business rules are being evaluated?

[rules-users] Drools Performance /Memory Leak Issue
Hi, I am not much of an expert on Drools. I got a DRL file (very small rule set of less than 10 rules, that checks few conditions, also includes DB calls). I use Drools 5.2 inside a grails application. I am using stateful session. I call this rules 100,000 times for each for each of the 100,000 records that I want to validate. However the performance gradually deteriorates. What could be going on here? General advice on how to approach solving this, improving performance. Should I be using stateless drools session? How do I configure the Drools MBeans so I can monitor Drools better? PS: I can provide more details as you needed. I can paste the general gist of the code and DRL file. Any help is greatly appreciated. I spent two days on this with no results.

Re: [rules-users] Validation flow - defer expression evaluation
There are a couple different options available.
I haven't tried it but some of what you are trying to do sounds suspiciously
like what you are trying to do is a workfow process or rules plan. Which
might mean you want to look at planner or consider how you are approaching
the problem.
If they were in the same group I know you can literally do what you want by
adding the salience keyword to one of your rules. example -
rule print mail messages
salience -100 // run this after other rules have finished
dialect mvel
when
$m : Message( )
then
System.out.println( Message was +$m );
end
I am not sure if it works between groups though I thought there were ways to
state order of group activation but that has never been part of the
documentation I use so I can't help you much there. But as a third option I
would suggest if you are using mvel you just use the feature of the language
to do null checks in the business logic if that is feasible for you.
Example
$var: user.?manager.name
is supposedly functionally equivalent to writing:
if (user.manager != null) { $var=user.manager.name; } else { $var=null; }
So you might just be able to test the data more elegantly inline. But it
really depends on what you are trying to do and why.
Hope this helped! If not I expect someone more familiar with the planning
or enterprise tools may speak up.

[rules-users] How to use lists in RHS when using MVEL?
I want to make an array and pass it to a method in the RHS but can't when I
use mvel. If I use mvel then java new Object[3] causes compile errors. If
I use the mvel syntax the object is not an real array, only a string in
mvel's special array notation which is not useful for the functions I am
trying to call. Working example:
rule Array bug
dialect java // explicit java or mvel barfs on new Object[];
when
Message( )
then
Object[] logArgs = new Object[3];
logArgs[0] = Sample string;
logArgs[1] = Another string;
logArgs[2] = And done;
System.out.println( Array was +$m );
end
If you change dialect above to mvel the code no longer compiles. If you
change it to mvel and use the mvel list syntax [Sample string, Another
string, And done] you don't have an array so methods requiring an array
do not work. Concrete example: I want to log 3 values using a logging
framework. Many logging frameworks (like sl4j) support a notation like
Logger.warn(My name is {} and you killed my {}, array); where array has
Inigo Montonya and father for values.
Thanks for any advice!

Re: [rules-users] Drools Performance /Memory Leak Issue
I assume you are calling dispose() after using each session? Using stateless session is an option as well. If so, with Drools 5.2 we had a problem with jbpm being in the classpath, fixed in 5.3. Did you tried Drools 5.3 yet? To enable MBeans, just use the MBeansOption.ENABLED in the KBase configuration, or set the system property: drools.mbeans=enabled.

Re: [rules-users] Drools Performance /Memory Leak Issue
Hi Edson, Yes I am calling displose(). No I have not tried 5.3 it, I will give it a shot. What was the issue with jbpm being in the class path, is it related to memory leak over time? AS for MBeans, thanks, I will try that also. What I am doing now is removed all rules, putting one rule at a time back running the performance test each time. What gives me hope is that when the rules was reduced to one or two I do not see any memory leak or performance issue (acceptable performance for our needs). So this gives me hope perhaps there are one or two offending rules out there. I am not a drools expert and I am sure some of the rules are not written in the best possible way. There are accumulations, collections, DB calls and what not. It is painful, but I am hopeful.

Re: [rules-users] Printing rule content when a rule is fired
I wish the Rule definition gave more detail than just a rule name, package name and metadata, or there was some way through the KBase api to get to it. Seems like I will need the to fetch the rule content from guvnor via REST (via some sort of timestamp versioning of my own) Thanks G.

I don't know if there is a way to get the content from the knowledge base, because as far as I know the knowledge base don't save the DRL file inside it, it just get the LHS of the rules to build the RETE tree.

[rules-users] Using Drools Flow with Multiple Fact Types
I'm a relatively new user to Flows, but I have worked with a colleague to instantiate flows that control a sequence of rule sets being applied to a set of data in a meaningful order (e.g. I do pruning to limit the set of facts as a first step, then generate sets of hypotheses, then score the hypotheses and select the highest-scoring instance as a winner), so I do have some experience and a baseline working Flow that is successfully operating. My next big challenge is to try to use Drools Flow to control which sets of rules will be applied to which subsets of data - this goes beyond the uses I have put it to before, which was just to control the single ordering of rule sets that was then applied to all data. My question has to do with the syntax of fact constraints used for controlling flow, and how to control the flow using constraints that reflect data characteristics when there are many different fact types that will be going through the Flow. I will use an analogy to the actual problem to make it a little simpler to describe. What I want to do is to apply different rules based on the Program that a particular Customer belongs to. If a customer is part of Program A, then I want to apply RuleSet A, and if the Customer belongs to Program B then I want to apply a different set of rules, RuleSet B. My problem is twofold: 1.) I have not been able to demonstrate constraints working as I expected, even when I simplified the data flow to its most basic form. The 'debug' version of the flow that I created has a diverging OR gateway (specifically OR, not an XOR gateway) with two criteria; the first is always true and therefore all instances should result in an instance of LogStatementA, and the second one has a constraint on the UserID associated with the customer and thereby limits the set that should be exposed to a rule that generates an instance of LogStatementB: Customer(userId 100) as an example of something I've tried, where any Customers with a UserID above 100 would then trigger an instance of both LogStatementA and LogStatementB, while customers with a UserID = 100 would only trigger an instance of LogStatementA. What I find is that if I set the constraint such that at least one Customer instance in the data should trigger the selection, then ALL of the instances of Customer in the data end up triggering an instance of LogStatementB (even those instances that do not individually meet the constraint), while if I set the constraint such that none of the Customer instances meets it, I get zero instances of LogStatementB. In both cases, I get an instance of LogStatementA for each Customer (as expected). I don't understand why the existence of a single match to the Flow Control rule (Customer(userId100)) would trigger all instances of Customers (including those with UserID's less than 100) to be routed to that path, while having no matching instances correctly avoids sending any Customers down this path. Is there a common type of error that I might have perpetrated that would cause this? I have tried a variety of combinations of the Type: and Dialect: settings, though intuitively it seems like Type: Rule and Dialect:mvel are correct given that I'm formulating the constraint as Customer(userId100). Also, if I introduce a typo in either the Customer or userId elements of the rule, I get errors that make it clear the POJO for this constraint is definitely being correctly imported. 2.) Assuming there is a fix to the underlying issue I'm seeing in #1, I will want to extend this example so that I am pushing more than just instances of Customer through my Flow. In particular, the rules that i want to expose the data to after the diverging gateway represent different flavors of the same type of logic, so what I want in the end is for all Customer facts to be sent either one way or the other, and all non-Customer facts to be sent BOTH ways. This will allow me, for instance, to apply different thresholds to customers depending on which Program they are part of. I first formulated an attempt at the control rule for this as: Customer(userId100) or not Customer with the idea that if the data coming through the flow is an instance of a Customer, then I want the constraint to be applied to determine if it proceeds down this flow, but if the data is not an instance of Customer then I always want it to proceed down the path (e.g. all Account instances, all RewardThreshold instances, etc.). Is this a valid way to expect to use Drools Flow? In the examples I've seen, there is only a single type of object that is going through a flow - am I breaking the spirit of Drools Flow in trying to get multiple types of facts flowing through? Assuming I'm not committing heresy in this basic desire of what I'm trying to do, is there an example anywhere of what the appropriate syntax for this kind of constraint would/could be? Any of the variants I have tried (and believe me, I've tried a bunch) have resulted
Re: [rules-users] Performance: StatefulKnowledgeSession.dispose()
I found the problem:
This is because I use log:
KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newFileLogger(session, test);
If I use Stateful session, The rule engine will print many log in XML file.
But if i use stateless session, it will not print any log.
my code is like this one:
for(int i = 0; i 100; i ++){
session.insert(new Object())//
session.fireAllrules();
}
session.dispose();
If I send 1,000,000 message, it will generate hundreds xml format log files.

Re: [rules-users] Drools Performance /Memory Leak Issue
HI, There was one bad rule, when I removed that memory leak is gone and the performance improved drastically!!! (from 60 sec for 1000 records to 10 seconds, satisfies our requirements) I am not sure what is wrong with the rule, I will check that tomorrow, I am a happy man now.
