Hi all, I would like to programmatically set up two Tomcat engines and have them form a basic cluster - all in the same VM. Creating and starting the servlet engines already works Tomcat tomcat = new Tomcat() tomcat.setPort( 123 ); // create context, add servlet, ... tomcat.start();
What I am struggling with is setting up the cluster. My first attempt was to use the PersistentManager with Store that uses a shared directory. But it seems that it only persists session in time intervals. To enable failover, a session would need to be persisted after each request. However, I didn't find out how to configure or trigger the PersistentManager to do so. Still, the PersistenceManager setup was straightforward and if anyone knows how to form a cluster with this approach I would be grateful to know. I am aware of the SimpleTcpCluster, which I would try next. Just, before transforming the XML configuration into API calls (without known their meaning) I wanted to ask if there is an easier or even pre-built solution. Background: I work on enabling RAP [1], a web framework, to work in failover cluster environments. To ensure cluster-support, I have a set of JUnit tests that issue requests against an embeded cluster of servlet engines and then examine the state of sessions of the respective nodes, etc. Performance isn't important, neither is any advanced clustering feature (e.g. DeltaManager) needed. My focus is on finding a lightweight and purely programmatic solution.
