[ https://issues.jboss.org/browse/AS7-3023?page=com.atlassian.jira.plugin.s... ] Tristan Tarrant updated AS7-3023: --------------------------------- Summary: Move topology information to JGroups subsystem (was: MuxChannel should generate addresses which implement TopologyUUID) Fix Version/s: 7.1.0.Final (was: 7.1.0.CR1) Git Pull Request: (was: https://github.com/jbossas/jboss-as/pull/896) Description: In order to support topology aware clusters, the addresses generated by MuxChannel must be of type TopologyUUID, otherwise Infinispan cannot compare address topology (this currently generates a ClassCastException). Also topology must be set before the channel is started. For this reason the topology tuple (site,rack,machine) should be set at the jgroups subsystem transport configuration and the Infinispan subsystem should merely retrieve it from there. (was: In order to support topology aware clusters, the addresses generated by MuxChannel must be of type TopologyUUID, even if the topology information is left blank, otherwise Infinispan cannot compare address topology (this currently generates a ClassCastException)) -- This message is automatically generated by JIRA.

[ https://issues.jboss.org/browse/AS7-3023?page=com.atlassian.jira.plugin.s... ] Paul Ferraro commented on AS7-3023: ----------------------------------- I don't think the JGroups subsystem is the appropriate location for this configuration. This type of configuration should really reside in host.xml. The JGroups and Infinispan subsystems should then be able to reference the proximity information from the configure socket bindings or similar. -- This message is automatically generated by JIRA.

[ https://issues.jboss.org/browse/AS7-3023?page=com.atlassian.jira.plugin.s... ] Tristan Tarrant commented on AS7-3023: -------------------------------------- Quoting Brian This is one of the use cases for expressions in the configuration model. So in the JGroups/Infinispan subsystem the relevant attributes would need to support expressions and the domain.xml configuration would use expressions: <host-topology site="${host-topology.site}" rack="${host-topology.rack}" machine="${host-topology.machine}"/> The host.xml server element can be used to specify the values: <server name="server-one" ...> <system-properties> <property name="host-topology.site" value="s1"/> ... </system-properties> </server> -- This message is automatically generated by JIRA.
