Rado, IMHO it would make sense, but this should be done in websubsystem definition so there is no need to define it in configuration as this system property is defined even if you run it in standalone. WebDefinition.INSTANCE_ID should be changed so it would have default value set to this. .setDefaultValue(new ModelNode().setExpression("${jboss.node.name}")) This way you get exactly the same functionality but without any xml changes. -- tomaz -----Original Message----- From: jboss-as7-dev-bounces(a)lists.jboss.org [mailto:jboss-as7-dev-bounces@lists.jboss.org] On Behalf Of Radoslav Husar Sent: Monday, March 26, 2012 3:18 PM To: jboss-as7-dev(a)lists.jboss.org Development Subject: [jboss-as7-dev] A default for instance-id? Would it make sense to default instance-id in HA profile to node name? instance-id="${jboss.node.name}" Node names in cluster already need to be unique [1] thus routes will be unique too and would solve problems like [2] as a side effect :-) When running single node, then mod_cluster automatic generation does the job. Just throwing it out there...
