BTW I've implemented Hazelcast EntryListener for hazelcast-map-Persistence feature [1] take a look at it as well.

Re: [Dev] Integration tests for Hazelcast Session Replication feature
Hi All, In WSO2 Operations Center we are currently supporting only forceful/graceful restart/shutdown. To do this, we use the ServerAdmin service. This is similar to restarting/shutting down the server with management console. If you want to restart/shutdown a server you can use the ServerAdmin service. IMO, If you want to simulate a instant exit of a server (kill -9) in s remote machine, you have to have some external agent program in that particular machine or use remote shell.

Re: [Dev] Integration tests for Hazelcast Session Replication feature
Running four nodes in single server is not recommended at integration tests phase, so killing a worker node at integration tests run time is not possible (Even no admin services exposed in worker nodes to forcefully shutdown the instance) I'm not sure whether upcoming operation center will facilitate this kind of functionality. Proposed deployment framework can be used to achieve this. However work is still under progress. You can find the relevant readmine at [1] Please find relevant mail discussions on worker node management in automated tests at [2] [1] https://redmine.wso2.com/issues/2083 [2] http://mail.wso2.org/mailarchive/dev/2013-November/024977.html Thanks, Krishantha On Fri, Oct 24, 2014 at 6:21 PM, Pubudu Dissanayake pubu...@wso2.com wrote: Hi Folks, I've implemented Hazelcast based Tomcat Session Replication feature for Appserver [1 https://redmine.wso2.com/issues/2816].I have few concerns over integration tests for this feature.
