[jboss-jira] [JBoss JIRA] Resolved: (JBAS-1476) Need to include a notion of cluster instance in the cluster view

Need to include a notion of cluster instance in the cluster view ---------------------------------------------------------------- Key: JBAS-1476 URL: http://jira.jboss.com/jira/browse/JBAS-1476 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering Affects Versions: JBossAS-4.0.1 Final, JBossAS-3.2.7 Final, JBossAS-4.0.1 SP1 Reporter: Adrian Brock Assigned To: Brian Stansberry We need to include a notion of cluster instance in the cluster view id to avoid at least the following scenario: Client serializes a handle to a cluster which is at cluster view 22 Handle contains key DefaultPartition/HAJNDI/22 The cluster is totally restarted meaning the view reverts back to one. The client now has a view id DefaultPartition/HAJNDI/1 The client deserializes the handle, which will overwrite the correct cluster view with the old invalid view. ---- This will also avoid the problem where a client talks to different clusters with the same partition name. ---- Proposed solution: 1) At cluster formation (first node in cluster), create a cluster instance GUID 2) At cluster join (second+ node in cluster) get the GUID from the coordinator 3) Include this GUID in cluster view keys, i.e. GUID/DefaultPartition/HAJNDI/1
