Re: [rules-users] Failing serialisation of large rule base

Hi, I have written a Java application that reads in approximately 6000 .dslr rules at runtime. This takes around 6minutes, however I have installed the application on the target (rather old!) machine and load time is in excess of 20minutes. I have been trying without success to find a way to speed up loading: I have tried: 1. Serialising the KnowledgePackages themselves. This works well but has limited effect on load time. 2. Serialising the KnowledgeBase, this does not seem to work on large rule bases and fails with StackOverflowException when I load more than about 200 rules. 3. Serialising the StatefulKnowledgeSession using Marshaller marshaller = MarshallerFactory.newMarshaller(knowledgeBase); marshaller.marshall(out, session); This works well for the life of the marshaller but does not solve my problem as I need to restart the application and therefore cannot use the same instance of marshaller later on. Marshaller is not serialisable. I know some of these points are discussed in other posts. But is there anything I can do or have I missed the point? Any help or comments very much appreciated, Regards, Jen -- View this message in context: http://www.nabble.com/Failing-serialisation-of-large-rule-base-tp24444231...
