We have some clustering tests for our app server using Artemis. We noticed frequent failures in these tests because the cluster of Artemis nodes is not formed in timely fashion. We use JGroups replication for our cluster communication. Usually, the tests fails because the cluster is not formed before we start testing things. What is the correct way to ascertain that a cluster is formed? Ideally I want to know how many nodes are in the clusters and how many of them are live. Please note that increasing a timeout after servers are started and before tests are exercised is not enough. There are some cases where the cluster is never formed at all (when playing with failover and tailback). But to test this use case, I first must be able to check the cluster topology in a reliable way. thanks, jeff -- Jeff Mesnil [email protected] http://jmesnil.net/weblog/
