Hello Ravendra,

I think you are looking for knowledgeBase configuration. The below code snippet might help you.

            // KNOWLEDGE BASE CONFIGURATION. The following properties are supported
            /*  
            drools.maintainTms = <true|false>
            drools.assertBehaviour = <identity|equality>
            drools.logicalOverride = <discard|preserve>
            drools.sequential = <true|false>             Can I use this ?
            drools.sequential.agenda = <sequential|dynamic>
            drools.removeIdentities = <true|false>
            drools.shareAlphaNodes = <true|false>
            drools.shareBetaNodes = <true|false>
            drools.alphaNodeHashingThreshold = <1...n>
            drools.compositeKeyDepth = <1..3>
            drools.indexLeftBetaMemory = <true/false>
            drools.indexRightBetaMemory = <true/false>
            drools.consequenceExceptionHandler = <qualified class name>
            drools.maxThreads = <-1|1..n>
            drools.multithreadEvaluation = <true|false>            Can I use this ?
            drools.mbeans = <enabled|disabled>
            */
            KnowledgeBaseConfiguration kbaseConf = KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
            if (Main.SEQ_MODE_RUN)
                kbaseConf.setOption(SequentialOption.YES);
            ruleSet = KnowledgeBaseFactory.newKnowledgeBase(kbaseConf); // (kbaseConf);

Hi Guys,


I am trying to find out  more information about rulebase configuration
options written in  "drools.default.rulebase.conf"

Do any of you guys know any blog or material written on these options,
If someone has written any blog on these options, and could I know the
location,  it will a great help.

Thanks,
Rav.

A very simple, yet effective solution would be to exclusively use
insertLogical(). No updates to facts which are already asserted, no
normal "insert".

You can grab the latest snapshot from this place:
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/

Or you can wait for Drools 5.2.M1. It should come out next week if
things go well.

Hey Chris

When doing the telnet from the client box i get:
"telnet: Unable to connect to remote host: Connection refused"

However, there's also another AS on that same server listening on port
8080
and there it's no problem to connect to that one.

Plus I also tried running JBoss on port 8080 (while having the other AS
shut
down), and also there the same problem:
Telnet local: "Trying 127.0.0.1... Connected to localhost."
Telnet remote: "telnet: Unable to connect to remote host: Connection
refused"

Considering that, it couldn't be a firewall problem, could it?

Thanks for the help!
Audrey

Hi everybody!

I'm struggling with the forEach construct. We already had a Drools Flow
running using Drools 5.0.
Now we would like to port it to Drools Flow 5.1.1.

It seems that there is a problem with the ForEach Construct in
combination
with the XOR Gateway (the same
seems to be true for the OR Gateway):

Even if i set both constrains of the gateway to "eval( true )" i got an
runtime Error like (full Stacktrace at the end of my post):
Caused by: java.lang.IllegalArgumentException: XOR split could not find
at
least one valid outgoing connection for split Art des Arbeitsanstosses
pruefen

I can even reproduce this behaviour when building a small workflow from
scratch.
Had anyone else such an error? Does anyone know a workaround for this?
You can reproduce this with the attached Flows.

Any help is really appreciated!
Regards,
Dirk Hermanns

P.S.: If i try to build such an Flow using the new bpmn Notation, i get
an
error when building the package in Guvnor: Workitem Node xxx has no
incoming connection.
So this doesn't seem to help :(. Has anyone got the forEach (or Multiple
Instances) feature with Drools 5.1.1 working?
