Batch processing large volume of Same type Of Facts

by mattmadhavan

Hello, I have millions of the same type of Facts which are read from the Datebase. The rules will go through each fact and produce an Array of derived records from the FACT. Do I need to process one FACT at a time or can I pass in say 500 FACTS at a time? I am using Stateless Session for this purpose. Can some one suggest me some ideas please? I appreciate in advance!

Re: [rules-users] Seting up test scenarios for Excel Decision Table with a map of data coming in

by abhinay_agarwal

/We would like to create a test scenario for each decision table (job type) which have varying number of condition columns, which contain between 5 to 25 different conditions./ This is pretty easy stuff, if you are using guvnor, you can directly create a test scenario inside the package where the model and rules are present In case you are not using guvnor, you will have to write JUnit test cases /What we are having trouble determining is how to pass a map of data to the test scenario via a declarative model/ You can directly insert a map object to your session -AA -- View this message in context: http://drools.46999.n3.nabble.com/Seting-up-test-scenarios-for-Excel-Deci...

Null pointer exception when adding drools to existing project

by kashili

I am having too many issues integrating drools into my existing code base, bcos I am unfamiliar with drools/jboss/maven. I have large code base and trying to add drools to it. I was able to run helloworld-drools from eclipse, but I cannot make it work when I add drools to existing project(File ->new ->drools->rule resource). I could compile, but I get null pointer exception when I run it (makes me believe that it has to add something to pom.xml or involved with other setup) I described my entire problem below. http://stackoverflow.com/questions/21466716/unknown-kiesession-name-in-dr... <http://stackoverflow.com/questions/21466716/unknown-kiesession-name-in-dr...> One of the threads in this forum speaks about wiki; I appreciate pointing me to any specifics in resolving this. -- View this message in context: http://drools.46999.n3.nabble.com/Null-pointer-exception-when-adding-droo...

[Optaplanner] provisioning / scalability

by Mats Norén

Hi, I have a use case where multiple users need to run multiple simultaneous solvers. Is there a best practice in scaling out Optaplanner for multitenancy? Just to be clear I'm not interested in scaling out a single optimization run but instead multiple solvers. So I'm looking for pros and cons for: - multiple solvers in the same JVM - multiple JVM:s on a single machine (with multiple solvers) - multiple machine setup - virtual machine vs lxc (Docker) vs bare metal I'm also interested in provisioning of rules etc Regards, Mats

How to add entity classes to Workbench?

by John Manko

I downloaded and configured Workbench (Guvnor), and I'd like to add my entity classes to it in order to create rules to manipulate their data. I don't see an JAR import function. Is this possible?

Clarification needed on Workbench

by John Manko

I need some clarification on Workbench. First, I'd like to use Workbench to allow business analysts create business rules to manipulate entity classes through the UI. Then, I'd like to export the rules from Workbench to a rules that will be loaded into our application for use by our Drools bean. Ifs this possible? Second, can rules reference EJBs or perform JPA queries? Thanks.

drools 6.0.0 examples?

by gallaxhar

I installed eclipse+drools plugin+drools 6.0.0 runtime, now I'm looking for the drools-examples zip file this page <http://docs.jboss.org/drools/release/6.0.0.Final/drools-docs/html/ch19.html> says, > Make sure the Drools Eclipse plugin is installed, which needs the > Graphical Editing Framework (GEF) dependency installed first. Then > download and extract the drools-examples zip file, which includes an > already created Eclipse project. Import that project into a new Eclipse > workspace.

infinite loop rule execution

by wtang

I am using a hashMap for my facts. That is I actually have all the facts in one big hashMap. Drools treats the hashMap as one fact and whenever I update this hashMap, all the rules are executed again and again. Would are the best way to solve this problem. I can use no-loop, but it has its draw back. -- View this message in context: http://drools.46999.n3.nabble.com/infinite-loop-rule-execution-tp4027980....
