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);
