<div class="jive-rendered-content"><p>Hello Maciej.</p><p>Thank you for your reply.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I explain the detail of app's architecture which I expect.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>1)How are you going to maintain your sessions?</p><p>Please refer  to "ClusteringImage1", it is the arquitecher which I want to make.(I added the attached file.)</p><p>The TaskClient and the TaskService is working on each servers and they are using same DB(postgreSQL).</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>TaskServerSessions are working in each servers and StatefulKnowledgeSessions are made in each servers.</p><p>When web app recieve user's request, web app send the msg to BPM engine. And BPM engine execute "making new session of the flow" or "starting and completing the task".</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The load balancer is controlling the request from the user's to webapp. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>2)is will you have your cluster in "share nothing" strategy or are you considering any caching mechanism?</p><p>About information of which are stored in jBPM's repositry,  I want to share these information between each servers0. And I think this issue can implement cause same DB is used by each servers.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Other than these I don't want to share in each servers. (If web apps need shareing the information, I will do it.
