[rules-users] Help write rule drools
My structure is composed of 2 classes (Node, Link)
class Node {
List Link out;
List Link in;
}
class Link {
Source node;
Target node;
}
they are inserted as facts in working memory.
I have to write a rule that will unite for each node joins the links that
have the same destination, and if there is then the inverse must also join
the latter.
eg.
A - link1 - B
A - link2 - B
A - link3 - C
C - link4 - D
B - link5 - A
result
A - link1 + link2 +link5 - B
A - link3 - C
C - link4 - D
Can anyone help me?

Re: [rules-users] Help write rule drools
How do you want the result? Printed lines on standard output? One for
each pair of connected nodes, as you have shown it below result? Or
collected in another fact?

Re: [rules-users] Help write rule drools
To remove all redundant Link objects and assuming that class Link is declared as
class Link {
Node source;
Node target;
}
(and not as given in the original post), the rule:
rule kill redundant links
when
$l1: Link( $s: source, $t: target )
$l2: Link( this != $l1,
source == $s target == $t
||
source == $t target == $s )
$n1: Node( out contains $l2 )
$n2: Node( in contains $l2 )
then
retract( $l2 );
modify( $n1 ){ getOut().remove( $l2 ) }
modify( $n2 ){ getIn().remove( $l2 ) }
end
removes all redundant Link facts and updates the out and in fields of
the Nodes at either end of these links.

Re: [rules-users] Help with event not found over window query
Thanks for your email below. I needed to refactor my code somewhat to get this technique to work but it solved the problem that I had. I was previously using fireAllRules() but I refactored the code to use fireUntilHalt() instead, which required some additional work to make a couple of other supporting features behave properly. I know you don't strictly need to do this, but it needed to be done anyway and it made sense to do it now. I would have thought it was quite a common scenario where someone wanted to implement business logic such as: - Something happens - It is expected that something else will happen within a certain time period of the first thing happening - If the second thing doesn't happen within the time period, generate an alert I ran into trouble because my various rules (from my original email) wouldn't fire an alert as expected when I fed in simulated events.

Re: [rules-users] Help on writing a rule
Am I wrong or do you have two PriceChange events - 392 and 394 ? If so, you can expect two activations.. when you fire al rules, one of the two will insert the OrderCreated, which in turn will cancel the other On 10/22/2013 01:34 PM, calcacuervo wrote: Hi Guys.

Re: [rules-users] Help on writing a rule
Yes! I receive many price change events.. but, as I am using window length = 1, I would expect to have the activation cancelled for the previous one? I am not sure how to express this: when there is some price change, and some signal, and there has not been any order over the last minute, then place an order The price change and signal are like existence facts.. If there is some price change change.. if there is some signal ... Would this be another way to achieve what I am trying to do? Thanks, Demian PS: This is a simple rule, but then, the idea is to have more complex rules.. like, if there has been 10 signals in the last time, place an order, etc. On Tue, Oct 22, 2013 at 5:40 PM, Davide Sottara dso...@gmail.com wrote: Am I wrong or do you have two PriceChange events - 392 and 394 ?

Re: [rules-users] Help on writing a rule
Mauricio, In fact, I used to have this and the price change without window:length.. but when t : PriceChange() signal : Signal( id == 1234 ) not OrderCreated( id == 1234 ) over window:time (1m) But this will cause more and more duplicates orders (and it have sense!). I added the length window to 1, as I would only like to create an order if there is some signal in the window, it can place an order..

Re: [rules-users] help on drools guvnor
Have you tested that the rules fire when you load them as DRL?
It would probably be worth showing us what EmployeeMap looks like and the rule
which you expect to fire if there is an EmployeeMap in working memory.
The Drools version would also be useful.

[rules-users] Help to implement my 1st planner
Hello everyone, i'm trying to implement drools planner for my paper and it
is proving very hard taking in consideration that i never user it before.
I was able to reproduce the examples, even though i got very confused, but
i undestood some things, but i'm really lost of how to implement my own
project/rule.
My paper is about service, I don't really know how to define it, but i'll
try to explain.
A given company receive several requests of maintence, repair, etc, all the
time, and it have a number of people to solve that, these technicians. It's
something like the nurse roaster but wy to simpler.
An issue can pop at any minute, it have a starting time and an estimated
time to be acomplished.
The technician have work for a fixed amount of time, but he have the start
time and the end time of work, that I want to use to assign the issue.
I've created the class Technician
Technician
import java.util.Date;
import com.thoughtworks.xstream.annotations.XStreamAlias;
@XStreamAlias(Technician)
public class Technician extends AbstractPersistable {
private int engId;
private int workTime;
private Date startWorkTime;
private Date endWorkTime;
private Technician technician;
public Technician(int engId, int workTime, Date startWorkTime,
Date endWorkTime) {
super();
this.engId = engId;
this.workTime = workTime;
this.startWorkTime = startWorkTime;
this.endWorkTime = endWorkTime;
}
public int getEngId() {
return engId;
}
public void setEngId(int engId) {
this.engId = engId;
}
public Date getStartWorkTime() {
return startWorkTime;
}
public int getWorkTime() {
return workTime;
}
public void setWorkTime(int workTime) {
this.workTime = workTime;
}
public void setStartWorkTime(Date startWorkTime) {
this.startWorkTime = startWorkTime;
}
public Date getEndWorkTime() {
return endWorkTime;
}
public void setEndWorkTime(Date endWorkTime) {
this.endWorkTime = endWorkTime;
}
public Technician getTechnician() {
return technician;
}
public void setTechnician(Technician technician) {
this.technician = technician;
}
}
Issue class
import java.util.Date;
import com.thoughtworks.xstream.annotations.XStreamAlias;
@XStreamAlias(CloudComputer)
public class Issue extends AbstractPersistable {
private Date startTime;
private Date estimatedTime;
public Issue(Date startTime, Date estimatedTime) {
super();
this.startTime = startTime;
this.estimatedTime = estimatedTime;
}
public Date getStartTime() {
return startTime;
}
public void setStartTime(Date startTime) {
this.startTime = startTime;
}
public Date getEstimatedTime() {
return estimatedTime;
}
public void setEstimatedTime(Date estimatedTime) {
this.estimatedTime = estimatedTime;
}
}
and here i got lost. I'm trying to schedule the technician to these issues
based on the estimated time and in the time left of technician.
I accept any kind of help or comment, I need it for next monday, i'll be
tunned everytime on this trying to make it happen.
Thanks for your time

My architecture is simple: one thread ran fireUntilHalt(), other (multiple) threads inserting objects. Should I synchronize on the session so only one thread is inserting at a time? There's one rule that triggers a large number of inserts, and it used to give me problems, but I've moved those inserts into Commands and those problems seem to have gone away. Any advice would be welcome, no matter how basic you think it is!

[rules-users] Help needed - how to get Number and intValue in Guvnor
Hello, I am new to Drools and trying to write rules using Guvnor GUI. I have uploaded POJO's that are required for my rules.

[rules-users] Help with URL resource caching
I'm using KnowledgeAgent to poll regularly for three DRL files hosted on a web server. If the web server goes down for any reason or one of the DRL files becomes unavailable, the change scanner and knowledge agent unsubscribe from the resource(s) that were unavailable. After reading some topics on the forum, I found that setting the drools.resource.urlcache system property should correct this. However, I've been unable to get this to work properly. The code I'm using is below. Any insight into what I'm doing wrong would be appreciated. I'm using drools 5.1.1. System.setProperty(drools.dateformat, MM/dd/); System.setProperty(drools.resource.urlcache, C:\\Users\\000\\Documents\\rule-cache); //start the scanner service and resource change notifier service changeNotifier = ResourceFactory.getResourceChangeNotifierService(); changeScanner = ResourceFactory.getResourceChangeScannerService(); changeNotifier.start(); changeScanner.start(); kagent = KnowledgeAgentFactory.newKnowledgeAgent(My Knowledge Agent); URL url = RulesRuntimeImpl.class.getResource(CHANGE_SET_PATH); Resource drl = ResourceFactory.newUrlResource(url); kagent.applyChangeSet(drl); My change set file looks like this: change-set xmlns=http://drools.org/drools-5.0/change-set; xmlns:xs=http://www.w3.org/2001/XMLSchema-instance; xs:schemaLocation=http://drools.org/drools-5.0/change-set drools-change-set-5.0.xsd add resource source=http://mysite.com/test/FirstDecisionTable.drl; type=DRL / resource source=http://mysite.com/test/SecondDecisionTable.drl; type=DRL / resource source=http://mysite.com/test/ThirdDecisionTable.drl; type=DRL / /add /change-set and the output I get when a resource in the change set becomes unavailable: [9/21/11 10:49:28:015 EDT] 004e SystemOut O [2011:09:264 10:09:15:debug] ResourceChangeScanner attempt to scan 3 resources [9/21/11 10:49:28:046 EDT] 004e SystemOut O [2011:09:264 10:09:46:debug] ResourceChangeScanner thread is waiting for 60 seconds.

Re: [rules-users] help! rulerule_key failed to predicate
Hi,
I thnik you might need to reposition dialect = mvel. The compiling error
will go away if you put it inside each of your rules. See example:
rule system will execute 'tc' command
when
dialect mvel
eval(Server.Message8388608)
then
System.out.println(The network is so crowd that it needs repairing.);
Runtime.getRuntime().exec(tc);#give the authority and execute the tc
command
end
rule caution
dialect mvel
when
eval(Server.Message==8388608)
then
System.out.println(caution!The network maybe will get blocked very
soon.);
end
rule fluent network
dialect mvel
when
eval(Server.Message8388608)#conditions
then
System.out.println(the current network is very good);#actions
end
Also, mvel is needed to make the eval statement work. In your case, it
might not be needed to work with eval at all.
WHEN Server.message should work as well. Providing you have an
attribute message in Server with a getter defined.
Regards,
Frank

The package declaration must be first.
You don't have to insert the dialect attribute into each rule.
Please consult the manual when programming.

Re: [rules-users] help! rulerule_key failed to predicate
How can we help you if you don't show us the text of your .drl file?
All I can see is that the DRL parser could not find rule (failing several
other alternatives) and then found the identifier com and didn't know what
to do with it.
This happens in line 4, position 0 (a misspelled import?) and 9 (com).

Try adding 'dialect mvel' (no single quotes) after the rule name to the
top of each of the rules. I have seen this error before and doing this
resolved the issue.

Re: [rules-users] help! the field *** is not visible
A better approach would be to use:- rule system will execute 'tc' command when Server(message8388608) then System.out.println(The network is so crowd that it needs repairing.); Runtime.getRuntime().exec(tc);#execute the tc command end This assumes you insert Server facts into working memory and they have a getMessage property.

[rules-users] Help with Accumulate function
Hi, I am having trouble implementing this rule with the accumulate function. My rule requirement is - Aggregate all PnlAttributionAmounts with a type of UNEXPLAINED for all Positions for a given day. Below is the code I have for this - $position : Position(date == $currDate) $posScn : PositionScenario(scenario == 'SCEN-EOD', position == $position ) $posScnGrp : PositionScenarioCurrencyGroup(positionScenario == $posScn, currencyType == CurrencyTypes.TRANSACTIONAL) $posPnlAmt : PositionPnlAmount(pnlAmountType == DTD, positionScenarioCurrencyGroup == $posScnGrp) $attibAmtType : AttributionAmountType(attributionAmountType == UNEXPLAINED/RESIDUALPNL) $totalPnlAttibAmt : BigDecimal() from accumulate( PositionPnlAttributionAmount(positionPnlAmount == $posPnlAmt, attributionAmountType == $attibAmtType, $pnlAttibAmt : financialValue) ,sum($pnlAttibAmt) ) eval ($totalPnlAttibAmt 1000) When I do it this way, the rule gets executed 6 times, basically for every fact that evaluated to true. How do I restrict this? The rule should be executed only if the final eval results in true.

Re: [rules-users] help with diagnosing CEP performance issue
ah, events werent being evicted because RHS was only evaluated during
fire(), which was after a batch.
i have altered my test code according to your suggestion, to look like this:
public void testLargeBatches() {
Node node1 = new Node(node 1);
node1.setId(1L);
s.insert(node1);
clock.advanceTime(1L, TimeUnit.DAYS);
int batchSize = 4;
int daysToRun = 10;
ArrayListBackup batch = new ArrayListBackup(batchSize);
ArrayListLong nodeIds = new ArrayListLong();
nodeIds.add(1L);
DateTime engineTime;
long start;
long accumulated = 0;
long currentTime;
long eventTime;
long delta;
System.err.println(days: +daysToRun+. batch: +batchSize+.
rules: +ruleFile);
for (int i=0; idaysToRun; i++) {
engineTime = new DateTime(clock.getCurrentTime(),
DateTimeZone.UTC);
batch.clear();
//generate random
System.err.println(preparing batch + i);
BackupGenerationUtil.fillBackupBatch(batch, nodeIds,
engineTime.minusHours(23).minusMinutes(59).minusSeconds(59),
engineTime.minusSeconds(1), batchSize);
System.err.println(feeding batch +i);
start = System.currentTimeMillis();
currentTime = clock.getCurrentTime();
//feed the batch in
for (Backup b : batch) {
eventTime = b.getFinished().getTime();
delta = (eventTime-currentTime);
clock.advanceTime(delta, TimeUnit.MILLISECONDS);
currentTime = clock.getCurrentTime();
backupStream.insert(b);
s.fireAllRules();
}
//advance a day (whats left of it)
delta = engineTime.plusDays(1).getMillis()-currentTime;
clock.advanceTime(delta, TimeUnit.MILLISECONDS);
s.fireAllRules();
accumulated += (System.currentTimeMillis() - start);
System.err.println(batch complete +i);
}
long averageBatchProcessingTime =
(long)(accumulated/(double)daysToRun);
double perBackupEventTime =
((double)accumulated)/(batchSize*daysToRun);
int eventsPerSecond = (int)(1000D/perBackupEventTime);
System.err.println(average batch processing time is
+averageBatchProcessingTime+ which is +perBackupEventTime+/event or
+eventsPerSecond+ events/second);
}
the batch is now ordered by event end time (inside fillBackupBatch() ), the
clock is advanced to the end of each event as it is processed and rules are
fired after each insertion. this code will eventually be run inside a j2ee
environment so i would rather not use fireUntilHalt() (also, using it
maxed-out a single core - does it do busy-waiting internally?!). also, the
batch nature is by design. the system will process events in a batch
fashion, not truly one by one. in production there will be many such batches
per day, but they could be very sizable.
for 40K events/day over 10 days, the above code (on my machine) lands me 59K
events/sec without the 2nd rule and 5300 events/sec with the second rule.
while this is an improvement of x2-x3 compared to my prev. code (24k without
the 2nd rule and 1400 with), for which i am very glad, i still cannot
understand why the 2nd rule slows me down by x10.
anything else i might do to get the performance if the 2 rules close to the
performance of the single rule?
2010/12/26 Wolfgang Laun wolfgang.l...@gmail.com
You are inserting a day's worth of backup events at a time. In this loop
the engine is forced to evaluate both rules, for an ever-increasing number
of events. It's the second rule that requires a comparison between any two
backup events, and this causes a quadratic increment in processing time.
CEP is short for continuous event processing, and that's what you should
let the engine do, i.e., not only evaluate the conditions but also the
execute the consequences. This is done by calling fireAllRules() after each
insertion. Alternatively, consider running fireUntilHalt() in once thread
and insert in another thread.
Ideally, the test should generate events ordered by time, and the
pseudo-clock might be advanced due to the time stamp in the generated
events. This would give you a very close approximation to a production run.

running this with or without the 2nd trimming rules makes a huge

Hi.
im trying to demo drools-fusion for a system that processes backup
events.
i have the following 2 CEP rules:
rule Backup Not Succeeded For At Least 3 Days
@ruleId(1)
when
Node($id : id)
not ( Backup(clientId == $id, $state: state ==
BackupStateEnum.FINISHED) over window:time( 3d ) from entry-point Backup
Stream )
then
//nothing for now
end
rule Prune Previous Successful Backups
@ruleId(2)
when
$prevBackup : Backup($id : clientId, state ==
BackupStateEnum.FINISHED) from entry-point Backup Stream
$newerBackup : Backup(clientId == $id, state ==
BackupStateEnum.FINISHED, this after $prevBackup) from entry-point Backup
Stream
then
drools.retract($prevBackup);
end
rule #2 is my attempt to cut down on memory usage. the problem is that
rule #2 slows down the processing very very considerably (2 orders of
magnitude slower when simulating batches of 40K events/day).
what would be my next step in trying to find the reason for it? my
intuition tells me that with 2 events in the system at any given time
instead of 120K (single node, 40K events/day 3 day window) i

To quote what I replied to an almost identical request a couple of days ago
and posted to the drools-user mailing list.
AFAIK, Activation Cancelled events would trigger in reaction to the
revocation of a logically inserted fact that caused an activation to trigger
in the first place. It would not help identifying which pattern in a rule
was not matched causing your rule not to activate.

Hello, I am newbie for Drools flow. I am trying to build work flow in which according to condition I have to ask either person properties or user properties. I am trying to embed it in web project. So I created 3 jsps. 1. Ask information about User or Product. 2. According to selection shows different options. 3. Display all the properties. What I am trying is, remove all the forwards from jsp and put them in workflow so that its easily supportable for new object as well. I think I should use Human Task where I am taking user input. Now i have below questions: 1. I am trying to use Human Task. But I can see it supports only Web Service Human task. Is it true??? 2. How can I use Human Task in this situation? In examples, I can see, I require EntityManagerFactory, mina Task which should run on some port. Is these steps really necessary??? 3. I am trying really simple POC where I require kind of web actor which should wait till user click on Submit button and then proceed to next step. Is any similar kind of support Drools have?? If yes how can i use it?? Small code snippets or doc link will be very helpful... Thank you very much in advance..

I have tried to use the following code Repository repository; JCRRepositoryConfigurator configurator = new JackrabbitRepositoryConfigurator(); repository = configurator.getJCRRepository( C:\\Programs\\Drools\\5.1\\jboss-4.2.3.GA\\repository\\ ); Session jcrsession = repository.login(new SimpleCredentials(admin, admin1.toCharArray())); RulesRepository rrepository = new RulesRepository(jcrsession); or RulesRepository rrepository = RepositorySessionUtil.getRepository(); My drools persistence is set to MySQL.

[rules-users] Help needed in Rule flow in Guvnor
Hi, I am using Rule flow in Guvnor for setting some value out of the flow which would be used for my further processing. Below is what I'm trying to achieve, I have two rule groups in the rule flow, out of which the first one would set a key, value pair in a Map which is a field in one of the bean class declared Global for the package when ever each rule is executed in the set of rules in the group and the next rule group would be required to have a set of rules that needs to be executed against this Map which was set in the first rules group and send the final result as output out of the flow. I have defined the rules in the first rule group and set the Map with necessary keys and values, but I was not able to read the Map in this second rule group. I had tried this second rule group as a custom java code in my Java part after the rules execution from guvnor and able to read the map that was set from the first rule group and able set the final decision. I want to know whether reading the Map from the second rule group which was set in the first rule group is possible or not. Or kindly let me know whether I'm missing anything here and needed to add any other logic to achieve the same.

Hi, In drools, I have seen that following functionalities have been implemented : - Creating a fact type which can be used in a rule - Creating rule by declaring functions or by using DSL - Testing the rule using test scenario Here, I had a question regarding decoupling of fact types between my application and drools. I wanted to whether writing a java code for adding values from form/database(i.e. my application) into fact types of drools package which I have created is must or is there any automated way for doing this ? For example, If new rule gets added which will result in changing fact (either modify existing or add new fact). In this case one has to write a code for populating presentation layer values into this newly modified/created fact type. Can this be automated..?

[rules-users] Help regrading branching of call to a rule depending upon date
Hi, I am evaluating Drool Gunvor for to implement Rules for some finance related functionality. I need help from users to implement following scenario is Drools-Guvnor I have created simple Rule to Calculate House Rent Allowance i.e. HRA as HRA = 0.12 * Basic salary .(Basic will come as Input Parameter). This rule is valid from e.g. 01-Jan-2005 to 31-July-2010 as HRA rule is changed from 1st Aug 2010 I will have to create new Rule for HRA Rule with new formula as HRA = 0.15 * Basic salary .(Basic will come as Input Parameter). This rule is valid from 01-Aug-2010 to 01-Aug-2999 From 1st Aug HRA should be calculated using New Rule. But at the same time if any Arrears to be calculated(back dated calculation) depending on the date old HRA rule should be applicable. Can I achieve this in Gunor Drool? I could achieve first half by specifying date-expires . But I am not able to achieve second half i.e. referring old rule depending on the date. I would appreciate help to solve this problem . Thanks in advance.

[rules-users] Help : Enabling Role Base Authorization in Guvnor
Hi all,
I try to enable the Role Base Authorization in Guvnor after it was running
fine with the default login mechanism.
But, encountered some problem with the attempt.
What I did was that in the components.xml,
- commented out the default security:identity
authenticate-method=#{defaultAuthenticator.authenticate}/
- uncomment the security:identity
authenticate-method=#{authenticator.authenticate}
jaas-config-name=other/
- change the role base authorization to true,
security:role-based-permission-resolver
enable-role-based-authorization=true/
And at the login-config.xml
I have changed the other application policy to
application-policy name = other
authentication
login-module code =
org.jboss.security.auth.spi.UsersRolesLoginModule
flag = required
module-option
name=usersPropertiesprops/guvnor-users.properties/module-option
module-option
name=rolesPropertiesprops/guvnor-roles.properties/module-option
/login-module
/authentication
/application-policy
guvnor-users.properties
admin=admin12
krisv=krisv
john=john
mary=mary
guvnor-roles.properties
admin=admin
krisv=admin,manager,user
john=admin,manager,user
mary=admin,manager,user
After restarting JBoss, I can login based on the user and password defined
in the guvnor-users.properties.
And, by changing the password in the properties, I verified that it is
taking in the value from the file itself.
However, when I login as user admin and tried to access the Administration |
User Permission or Event Log,
I'm prompt Sorry, insufficient permissions to perform this action.
The error from the console is
11:15:36,046 INFO [STDOUT] ERROR 29-07 11:15:36,046
(LoggingHelper.java:error:76)
Service method 'public abstract java.util.Map

at
org.jboss.seam.security.Identity.checkPermission(Identity.java:581)
at
org.drools.guvnor.server.ServiceImplementation.listUserPermissions(ServiceImplementation.java:2604)
.
Checking on the org.drools.guvnor.server.security.RoleTypes code, the
available role should be
admin
analyst
analyst.readonly
package.admin
package.developer
package.readonly
Can anyone help to let me know what's wrong with my configuration?
Thanks.

[rules-users] Help : Can't see process in gwt-console
Hi, I'm trying to start a sample process in the gwt-console by following a video tutorial and list thread http://blog.athico.com/2009/10/drools-51-m1-release-notes.html http://markmail.org/message/y4sae37xvv44shhh What I did was - start h2 - start human task - start jboss It looks to me that all the services are started without error. However, I'm not seeing the process in the gwt-console - Processes view. The process I have loaded in Guvnor is not available in the gwt-console. I have uploaded 2 processes in Guvnor through Eclispe. 1 of them is a .rf file and the other is a bpmn file. And, I also notice that the Settings - System view, the ProcessEnginePlugin is still a red cross. And, the log shows 10:38:00,062 INFO [STDOUT] 10:38:00,062 INFO [PluginMgr] Successfully loaded plugin 'org.jboss.bpm.console.server.plugin.FormDispatcherPlugin': class org.drools.integration.console.forms.FormDispatcherComposite 10:38:00,062 INFO [STDOUT] 10:38:00,062 INFO [PluginMgr] Successfully loaded plugin 'org.jboss.bpm.console.server.plugin.GraphViewerPlugin': class org.drools.integration.console.graph.GraphViewerPluginImpl 10:38:00,078 INFO [STDOUT] 10:38:00,078 WARN [PluginMgr] Unable to load plugin: 'org.jboss.bpm.console.server.plugin.ProcessEnginePlugin' I have upload some screenshots of the different pages to here. http://img826.imageshack.us/g/gwtconsolesystem.jpg/ Thanks for any advice.
