[rules-users] Organizing Rules in Large Enterprise across multiple business lines
Can any body suggest the way to oraganize and share rules for mutiple business lines with each having multiple apps Basically I am looking at Business Rule management , development and deployment best practices across the organization taking into consideration all Business Units that needs Rule based apps. option 1) Have one run time deployment (Expert engine) for all these apps with large memory. option 2) Have one BRMS/Repository for all the rules in the enterprise across the business lines and then a sperate run-time for each app/business unit ? If we assign a package for entire rules in a Business unit or BU_App can we have permissions around package so that certain project teams can work on those packages but not others. Option 3) Should one team be responsible for all the rules in an enterprise ( across BUs ) and provide decision services to the corresponding apps in each BU ? Any references on web is great!! ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Drools Guvnor Remoting API
I am also lookign for similar features(API) from Guvnor. I am using Eclipse Drools Plugin. I want to build the rules on IDE and deploy the compiled rules package to Guvnor and want the Rules app to use the packages from Guvnor URL. Also is there a way to make Guvnor use SVN instead of JCR? thanks Sumant From: Steve Ronderos steve.ronde...@ni.com To: rules-users@lists.jboss.org Sent: Tuesday, August 4, 2009 11:42:33 AM Subject: [rules-users] Drools Guvnor Remoting API Hello Again, I asked a question similar to this awhile back, David Sinclair answered some of my questions, but I'm still looking for a few features. Here is my use case. We are deploying Guvnor to an enterprise environment. We plan on having one Guvnor for our rule authors to create/edit rules in. We plan on using selectors to control which rules are included into packages that are built for different environments (development, test, production). We can't have our application that use rules pointing directly at the Guvnor instance. We want an automated deployment process. Here is what I was thinking. I would like to be able to invoke a build, using a specified selector, then create a snapshot that follows a specific naming convention (ie with the selector's name in the snapshot name), in sequence. In order to do this, I would like to, from a remote application, tell Guvnor to do a build, then to do a snapshot. So essentially what I'm asking for is a remoting API for Guvnor's features. I've looked through some of the Guvnor code and I believe I see that there is a remote API for the drools-repository that Guvnor sits on, but what I need is specifically Guvnor's features to be made available in a remoting API. Does anyone know if such a thing exists? If not is it planned? If not, am I even asking for a desirable feature?

Re: [rules-users] Relation between Guvnor and Expert in Drools5.0
Thanks Vijay. I think I have few more questions. 1) Does Guvnor include the runtime or Rule engine it self ? I could create rule and execute it in Guvnor so does this mean it has Expert included in it. 2) When a end user/app executes/fires a rule where is the rule runtime, is it the client JVM or Guvnor JVM ? In other words are rules executed in Guvnor that are packaged and made available on Guvnor or will they be marshalled to the client calling the rule and executed in client JVM. 3) Can you give an example of Drools5.0 deployment pattern. How Guvnor,Expert and J2EE app will communicate. thanks Sumant From: Vijay Pandey vpan...@mdes.ms.gov To: Rules Users List rules-users@lists.jboss.org Sent: Tuesday, July 28, 2009 5:52:07 PM Subject: Re: [rules-users] Relation between Guvnor and Expert in Drools5.0 Guvnor àThis can be used to manage your rules specifically termed as BRMS (Business Rules Management System).

In other words are rules executed in Guvnor that are packaged and made available on Guvnor or will they be marshalled to the client calling the rule and executed in client JVM. Rules are only executed in Guvnor when run in a test scenario. Rules are exposed by Guvnor in form of compiled packages. You can use them in your local Drools application through a Drools Agent [1]. 3) Can you give an example of Drools5.0 deployment pattern. How Guvnor,Expert and J2EE app will communicate. One option is the Drools Agent.
