[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. The rules all have example classes that execute the rules. If
> you want to try the examples in another project (or another IDE) then you
> will need to set up the dependencies by hand, of course. Many, but not all
> of the examples are documented below, enjoy!
>
> Some examples require Java 1.6 to run.
However I could not find instruction as to how to get this file.

Marshalling/Unmarshalling of KieSession
by IK81
Dear all,
I've to questions concerning the marshalling and unmarshalling of
KieSessions.
First, is there any detailed documentation on the
ObjectMarshallingStrategy interface? I am quite confused about the
purpose of the write and read methods in the interface. In my
implementation they are never called. Are they deprecated or under which
circumstances are they called by the implementation?
My second question is about the relationship of the KieSession, KieBase
and the KieContainer in case of marshalling/unmarshalling. Assume that I
create a KieSession based on a KieBase that is created from a
KieContainer based on a release X. When marshalling this session, is
there any information marshalled about which release this session is
based upon? I am asking since when I unmarshall the session I want to
ensure to initialize the unmarshaller based on a KieBase with the same
release X as the marshalled version of the session. Do I have to store
this information out of band or what's the recommended way to implement
this?
Thanks,
Ingo
