Rule to load facts with pagination
by mariofox
Hi.
I'm running drools in a project with millions of facts to process. My memory
doesn't allow me to load all of my facts, so I have to load N objects at
once, then start over with next N objects, and so on.
Is it a good idea to let Drools to manage Pagination? I mean, create rules
in Drools with the purpose of loading facts?, or should I have to do this by
executing a Drools session from java in a loop?. My main goal is
performance.
Thanks!

upgrading drools-server 5.0 to drools-camel-server 5.4
by bhochhi
After 2 years, I am trying to upgrade from drools 5.0 to latest. The way we
are using the drools: the client apps(in c# and ruby) sends the request to
drools-server 5.0. This execution server gets the rules .pkg file from
guvnor using the properties files that map rules package at guvnor and
response with output of rules execution. Unfortunately, the new execution
server doesn't seems to work same way as the new one is completely
different. I deployed drools-camel-server-5.4.war and saw how test.jsp is
working. Then I changed knowledge-service.xml to replace the local drl
resource to remote pkg at guvnor as follows:
<drools:resource type="DRL" source="classpath:test.drl"/>
to
<drools:resource type="PKG"
source="http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/test/ex"
basicAuthentication="enabled" username="admin" password="admin" />
When I ran the test.jsp, I got exception, snippet below. There were few
other warning exceptions too, but not sure which is cause this problem. To
make my question short, I want to know is there at quick example or docs
that explain how I can use drools-camel-server to response the
actions(output of execution) to external app that sends the request with
conditions, where camel server gets the rules pkg from guvnor? I have create
the jersey based webservice to do exactly the same, but I want to understand
how this new camel-based server works. I appreciate any kind of your help.

Some problems with Deploying drools-camel-sever 5.3.x in Weblogic 10.x
by ndipiazza
Hey everyone,
We have been trying to deploy drools-camel-server-5.3.x.Final.war from
droolsjbpm-integration-distribution-5.3.0.Final on WebLogic 10.3.3.
We hit a series of issues, of which I've opened up some issue tickets to
address:
1) strict web application container complains about web.xml (JBRULES-3403 -
https://issues.jboss.org/browse/JBRULES-3403) - web.xml needs to be
re-arranged to get it to work in weblogic 10.x.
2) There seems to be duplicate JPA persistence units
(https://issues.jboss.org/browse/JBRULES-3404)
I also experienced two other issues that I do not feel comfortable putting
on the issue tracker because they may be weblogic-specific:
3) When I tried to run a SOAP UI test on the drools server in Weblogic
10.3.3 I get this:

Seems to be two possible ways to solve this (have not tested these yet!)
Option One: Use axis.jar instead of saaj-impl.jar
1. add axis.jar file to bea class path
2. in startWebLogic.sh/cmd
set JAVA_OPTIONS=%SAVE_JAVA_OPTIONS%
-Djavax.xml.soap.MessageFactory=org.apache.axis.soap.MessageFactoryImpl
Option Two: Make a code fix to allow the saaj to function
Follow the below steps to resolve "UnsupportedOperationException"
a. Set classpath to latest saaj-impl.jar in startweblogic.cmd
b. Set the below 2 system properties in code.
System.setProperty("javax.xml.soap.MessageFactory","com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl");
System.setProperty("javax.xml.soap.SOAPConnectionFactory","weblogic.wsee.saaj.SOAPConnectionFactoryImpl");
c. Note that the above 2 classes are available in the saaj-impl.jar which i
have used and set classpath in step1. If you are using different version of
saaj-impl.jar, set the exact "MessageFactory" and "SOAPConnectionFactory"
classes which are avilable in your saaj-impl.jar. (Just extract your
saaj-impl.jar and findout the exact classes).
Obviously we cannot expect Drools team to make any code changes with respect
to WebLogic, so I would imagine trying Step 1 is the best way to go.
4) The drools-camel-server.war’s test.jsp apparently runs an example that
uses a Camel route leading to a REST web service. This does not work for me
either off the bat:

Apparently the camel endpoint did not deploy at all, or something.
I'm wondering what of these issues are totally specific to WebLogic, and
which are just plain 'ole issues. Can anyone share their experiences or
expectations of using the drools camel server WAR within the various app
servers? How much are we expected to make custom changes?

Logical assertions & the KnowledgeBaseConfiguration insertion modes.
by bardelman
Hi ,
i ve read that when the same fact is logically inserted into a session by
more rules, only one equal instance will be physically present in the
session.
On the other hand, i learned that Drools supports two fact insertion modes
:equality and identity.Identity (which is the default) means that no two
objects with the same JVM object reference can be inserted into the
knowledge session.
what if the equality mode is set and the logical assertion is used ? does
these modes only concerns the non logical assertion and not the logical?
i ve found in an exemple in the Drools-JBoss-Rules-5.0-Developers-Guide,
that each logically inserted fact has a counter which is incremented every
time an equal fact is inserted. Does this counter belongs to the drools
specification ?

5.4.CR1 Guvnor bug?
by Sean Su
Attached is the repository exported from 5.3.final. There are two issues
here.
I would appreciate it if the development can take a look.
1. The last column of the decision table does not display any values on
5.4.CR1 while it works fine on 5.3.0. Please note the rules are still
generated correctly and it even passes the validator from 5.4.CR1. However
there is some GUI issue here.
2. If you generate a deployment Snapshot, everything seems fine. However
when trying to access the generated file (from the link provided by
Guvnor), I get the NullPointerException. This can be reproduced in both
5.3.0.final and 5.4.CR1, though the trace from 5.4.CR1 is shorter.
I initially reported this NPE couple of days ago under the assumption that
it is caused by Guvnor and Joda time integration. But it seems it happens
(randomly) in that situations.
Thanks
Sean

To bind a field, once the field has been added to the Fact type simply click on the field name.
With kind regards,

Following your steps, I couldn't understand a point: how can I bind a field(for ex. RadiationObservation.location) to a variable?
specifically,
$obs : RadiationObservation(?$obsLocation : location? ) over window:length (1) from entry-point "lowLevelSensorStream"

Think of a stateless knowledge session as being a statefull knowledge session, with the following adjustments:
A stateless knowledge session cannot be manipulated prior the start of the session.
A stateless knowledge session cannot be manipulated or queried after the end of the session.
A stateless session begins when you execute the fireallrules method.
A stateless session ends when the rule processing terminates. -- There is no pause, there is no restarting. The instant the rules stop firing, and return to your calling code, the knowledge session has been torn down.

hi folks, this is a simple question ,
i just want to understand how is it possible that a stateless session have a
setGlobal() method as it does not maintain a state. What's the point ?!
i also have some confusion between a "request scope" and a "stateless
session scope" i think it s the same..

Sure.
- Create "New Rule"
- Add a condition (green + near "WHEN")
- Select "From Entry Point"
- Type "lowLevelSensorStream" into TextBox
- Click on "click to add patterns..."
- Select your Fact Type (see * below)
- In "Over sliding window" ListBox select "Length"
- Type "1" into the TextBox next to "Length".
* OK, so this is possibly where you're having problems.
In order for a Fact Type to be used with CEP it needs to be annotated as an
Event. This is how this can be accomplished:-
*If you have a Declarative Model
*
- Open the Declarative Model
- Select the Fact Type that should be an Event
- Add an Annotation, name="role", key="value", value="event"
- Save
*If you have a POJO Model*
- Create a new Declarative Model
- Add a Fact Type that matches the name of that in your JAR
- Add an Annotation, name="role", key="value", value="event"
- Save
Annotating your POJO is covered in the Drools Expert User Guide. You are
just using Guvnor to achieve what is required.
With kind regards,
Mike

I have not yet determined how I want to implement my problem and was hoping
to get some feedback.
I am using drools to migrate the logic from my automated currency trading
infrastructure. Each currency pair, i.e. eurusd has around
200 attributes associated with it.
This includes range values (high, low, average) for multiple time periods,
volatility information, bid/ask updates etc.
Currently I have classes associated for each, so say for range:
class Range {
double high;
double low;
double avg;
}
Range europe = new Range(); //european trading hours
Range us = new Range(); //us trading hours
Questions:
1. I am wondering if I should not just create a map that lists every
attribute per pair as a key ("eurusd:range:europe:high")? So essentially
my drools session will have one fact, not counting the incoming quotes. I
see on the list that this was a problem before the mvel updates but that
was a while ago.
2. When an incoming quote might modify a value, what is the performance
difference between using a rule to change the value or making the changes
outside of the ksession and referencing the facthandler to modify? Is one
method considered 'cleaner'?
Thanks,
Bobby

What I am prototyping is part of the event processing (with or without
fusion). I want to use the rules created by the Guvnor to create the new
events. However, as you would understand, once the event has been created,
it should not be modified as it happened in the past.
So I am trying to avoid setters if possible.

Seems reasonable enough.

Re: [rules-users] modify, retract, setFocus and Salience
by gboro54
I will take a stab at answering this:
-Modify and Retract will cause the tree to be re-evaluated for the current
facts in memory. This may cause new activations or cancellations to occur.
Be forewarned that a rule that modifies a fact may cause a continuous loop
if the conditions for that rule are always satisfied. If you wish to not
have this behavior look at no-loop
-Salience: Can be useful but I have found that using a controller fact to
order execution is more efficient. The problem with Salience is that it can
cause your tree to become to linear thus the behavior of the rules engine is
more like a bunch of if statements rather then being able to match patterns
and fire. I do use salience for some rules but try not to over do it
-setFocus: I don't have anything wrong with this. This allows you to
segments your rules into agenda groups.
I am sure someone else on here can add more.
