Re: [rules-users] How to monitor drools execution time?
You can use the Drools guvnor to measure the execution time of each rule. This is the feature of that.

Re: [rules-users] Memory issue with drools (using 10000 rules)
is it necessary to execute 1 rules in one time for your case?
Why don't execute rule selectively?
2011/4/26 Mark Proctor mproc...@codehaus.org
There is no out of the box way to improve that, beyond just partitioning
your rulebases yourself.
If you would like to get involved in RD we can do lazy network building
and try pushing unused parts of the rule network to disk.

Hello All,
I’m working at HP Software RD and we are considering using drools in our

Benchmarking tests showed that running 10,000 rules consumes 382mb.
This is too high for our system requirements, and we would like to know how
we can improve it.
Technical details:
- Drools version: 5.1 with default configuration.
- All rules look like this:
rule status-Fixed-Open
when
event : FieldChangedEvent(fieldName ==
status, oldValue == Fixed);
entity : Entity(entityType == mock-entity);
eval(((String)
entity.getFieldValue(status)).equals(Open));
then
do Something…

for(all resources)
{
knowledgeBuilder.add(resource, ResourceType.DRL);
}
knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase();
knowledgeBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages());
Any insights are most appreciated.

Re: [rules-users] execute particular rules programmatically and dynamically
Hi Bob,
Let me try to implement the AgendaFIlter :
import java.util.List;
import org.drools.runtime.rule.Activation;
import org.drools.runtime.rule.AgendaFilter;
public class RuleNameContainsAgendaFilter implements AgendaFilter {
private ListString rules;
public RuleNameContainsAgendaFilter(ListString rules) {
this.rules = rules;
}
public boolean accept(Activation activation) {
// TODO Auto-generated method stub
String activationRuleName = activation.getRule().getName();
if(rules.contains(activationRuleName)) {
return true;
} else {
return false;
}
}
}
I think the above the AgendaFilter can resolve the particular rule
execution value, i.e. Just pass all the specific rule into a List
object and create the above AgendaFilter, then those particular rule
can be executed.
Please comment.

Hi, Here is the scenario : If there are 2 edit boxes and 2 dropdown list at the frontend like. dropdown(minIssrdAge1) editbox(age1) dropdown(minIssrdAge2) editbox(age2) everytime when I lost focus the editbox(age1 or age2), the editbox(age1 or age2) value will be validated against the following rules. i.e. minIssrdAge1 and age1 will be validated together if lost focus the editbox age1. minIssrdAge2 and age2 will be validated together if lost focus the editbox age2 Rule1 is mandatory because both editbox are required field. However, editbox(age1) is only valid within the 0 and 100. and editbox(age2) is only valid within 0 and 600. In other words, editbox(age1) have to be validated against Rule1 + Rule2. However, editbox(age2) have to validated against Rule1 + Rule3. My question, how to design the rule attribute or at the java program side so that different editbox can be validated against different rule. Please help.

Hi Michael, Can you elaborate more for the uses of the ApplicationContext? I can't follow its uses. Thanks Benson 2011/4/14 Michael Anstis michael.ans...@gmail.com: Here's a quick (and probably sub-optimal way) ;) When you copy values from the UI to Facts for validation you also include the context of the validation.

Re: [rules-users] execute particular rules programmatically and dynamically
Good, Michael. 'context' is used to distinguish which part of the UI which will be validated, right? The customer will ask if they have 1 rules in the rulebase. And some of them are redundant, so they want to make some of the rules share with several part of UI, e.g. editbox 6, editbox 7 and editbox 8 these 3 boxes' value range is within 0 and 600. Therefore, Rule3 can be shared for these 3 editbox validation, right? However, for the context variable approach, it seems Rule3 cannot be shared for another editbox with same value range validation. So these could be a key for the BRMS/Drools. Benson 2011/4/14 Michael Anstis michael.ans...@gmail.com: Sure, whenever you copy values from your UI to your model for validation you also enter a fact representing the context of the values. Using your example you have two edit boxes on one screen and your rule simply checks for the value of a single edit box; in this case the context differentiates the two. Walking your example: (1) When editbox 1 looses focus you copy the value from the dropdown and edit box 1 into your model, plus you enter a context fact stating that these values relate to that part of the UI (say screen1.panel1.editbox1). You then insert these facts into WM and call fireAllRules. The rules check the context and only execute if the values are for the (rule) applicable context. (2) Editbox 2 works in a similar way, but has a different context ((say screen1.panel1.editbox2). Have a look at Plugtree - I believe they're quite well customed to writing UIs backed with rules; salaboy or esteban (or IRC #drools) might be able to offer more practical advice.

[rules-users] Strange java.lang.NoClassDefFoundError
Hi,
I have a GWT RPC method as follows :
public String validate(ApplicationData ad) {
Object dataObj = null;
KnowledgeAgent kagent =
(KnowledgeAgent)getServletContext().getAttribute(KNOWLEDGE_AGENT);
KnowledgeBase kbase = kagent.getKnowledgeBase();
StatefulKnowledgeSession sf =
kbase.newStatefulKnowledgeSession();
FactType ft = kbase.getFactType(axaPMTPOCPackage,
ApplicationData);
try {
dataObj = ft.newInstance();
ft.set(dataObj, name, ad.getName());
ft.set(dataObj, sex, ad.getSex());
ft.set(dataObj, minIssrdAge, ad.getMinIssrdAge());
ft.set(dataObj, age, ad.getAge());
ft.set(dataObj, boxname, ad.getBoxname());
sf.insert(dataObj);
RuleNameStartsWithAgendaFilter filter = new
RuleNameStartsWithAgendaFilter(ad.getRuleName());
sf.fireAllRules(filter);
sf.dispose();
} catch(Exception e) {
e.printStackTrace();
}
String returnMsg = (String)ft.get(dataObj, returnMsg);
return returnMsg;
}
At the client side, I made 2000 times of the above ajax call to
validate 2000 fields.
However, I got the following java exception after making certain
number of calls.

Hi,
Please note that, if I make 200 ajax call to validate 200 fields. It
works fine without any problem.
But if validate 2000 fields, the exception comes up. Please advise
what is the root cause in the BRMS(Drools Guvnor).
Thanks

Re: [rules-users] execute particular rules programmatically and dynamically
The reason is that as the no. of rules in the rulebase grows, it is possible that some of the rule can be re-used/shared for specific purpose. I am not sure this is the good reason. Of course, like you said, if it can solved by using agenda-group, activation-group, salience. That will be wonderful. Thanks 2011/3/31 Michael Anstis michael.ans...@gmail.com: Why would you want to execute a single rule? The logic you'd write to determine which rule to fire should itself be part of the rules: So, for example, if you want to validate facts of type Smurf then write a rule that matches on Smurf. When you insert a Smurf only the rules that match on this will become candidates for execution when you call fireAllRules. Perhaps use of a stateless session would simplify things so you need not worry about other facts in WM polluting the results you expect to see?

Steve 2011/4/1 Swindells, Thomas tswinde...@nds.com Agreed, But if you really do want to you can setup an agenda filter so that only the activation for the rule you care about is fired – but I don’t think there are many valid cases where this is needed/desirable/appropriate.

Yes, this is simple and easy to simple. However, if the solution is an enterprise level with tons of rules. It will have a lot of rule files in the repository, it will make the rule maintenance/house-keeping difficult. I prefer to design an algorithm/framework programmatically to handle this situation.

Hi Leonardo, Thanks for your patience. Let me try to describe what I want in details. e.g. There is a variable A with 3 rules in BRMS. The variable A is input by a user via an edit box at the frontend. Now there are 1000 rules in the BRMS rulebase. However, 3 out of 1000 rules are related to this variable A, like rule 'check_a_empty' when (( A == null) || (A == ) ) then return a message 'A cannot be empty' rule 'A_Range_0_100' when ((A 0 ) || (A 100) ) then return a message 'A must be within the range between 0 and 100' rule 'check_A_Character' when ((A is not an integer)) return a message 'A must be an integer' If I would like to execute the above 3 rules at the same time, how to write/develop the AgendaFilter class?

Could you tell me how you can upload ~76,000 rules in 7 minutes to the package? It is very fast. Please advise Thanks 2011/1/14 Joe White joe.wh...@recondotech.com Hey Edson, Right now we use only one builder and we add one large file. In the past we used multiple builders and files but using a single builder with one large file is much faster. I will have to gather the timing for the differences for the package call versus adding to the kbase. Right now we only collect the combined time. We are still on an older version but are upgrading now to 5.2. I’ll let you know if the new API helps. I’ll give trunk a shot but I won’t be able to use it because we are targeting having this large rulebase in production in mid-February. For reference our current largest production rulebase is ~76,000 rules. Those rules take around 7 minutes to add to the package and the rulebase in a JVM with 2GB of allocated heap.

My guess is it would be a bit faster as the consequence would be compiled only once, but I have no numbers to compare... question: are you using a single builder and adding multiple files/rules to it, or are you using one builder per file? Is your application spending most of the time on the builder or adding rules to the kbase? I see you are still using the old API (method addPackageFromDRL())... does the new API make any difference? Also, I know Tihomir was improving perf in trunk by caching the configuration file... did you tried trunk? Does it make difference for you? Edson 2011/1/13 Joe White joe.wh...@recondotech.com For a large rulebase (200k+ rules) will the call to addPackageFromDrl(drlString) run faster if the number of rules is smaller but the rules include more || statements between predicates? There is only one type of object ever inserted in working memory and I have many rules with the same RHS. I can collapse those rules into one LHS with ors between the predicates in the object, but I would only go through the effort of optimizing if it would improve load time. Thanks for your help.

[rules-users] Looking for smart way to import huge amount of rules into BRMS
Hi, I need to import a drl file with 9000 rules inside into BRMS. However, I found that it takes very long time to import and it also takes long time to get downloaded into the application to build the ruleBase. Is there any smart way or faster way to manage this procedure? Please advise Thanks ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] KnowledgeAgent and applyChangeSet
can you capture the exception for reference? Looks like I got similar exceptions before. On Wed, Jan 12, 2011 at 12:31 AM, bob.breitling bob.breitl...@rrd.comwrote: If I have a KnowledgeAgent and I create a URL Resource and set its basicAuthenication, username and password attributes then I call the agents applyChangeSet method I get a HTTPD 401 response from the Guvnor. It does not happen to my resourse which has a valid username and password, but it happens to the resource in the changeSet xml tag. It would seem to me that the resources that are built from the resource I passed would inherit the basicAuthenication, username and password attributes that I set and know work, but they don't and I get this error. If I debug the code and filling in those values on the resource passed to the createPackageFromResource method before the resource stream is read the code works. I am using the NilAuthenicator in the Guvnor components.xml and that seems to be working. I get access to the Guvnor without being asked for credentials.

Re: [rules-users] QA features in BRMS
Hi Esteban, Could you elaborate with your wordings 'audit rules'? I mean if there are two rules with same conditions but different consequences within a package, it could not be an error/warning as you said. Could you give me an example/typical situation? Thanks for your explaination. 2010/12/30 Esteban Aliverti esteban.alive...@gmail.com This is because the scenario you are describing is not always an error/warning.
