[jboss-as7-dev] purpose of jboss.node.name and how to set.

I'm a bit confused about the purpose of 'node-name' and how to set it. I found out that the nodes name is required for UserTransaction and also a notice: https://docs.jboss.org/author/display/AS71/Clustered+EJBs If it's on the same machine, the two things you have to make sure is that you pass the port offset for the second instance and also make sure that each of the server instances have a unique jboss.node.name system property ==== standalone ==== In this mode the only way to set is to use '-Djboss.host.name='. I try to use <server name="MyNode" xmlns="urn:jboss:domain:1.1"> OR <system-properties> <property name="jboss.node.name" value="MyNode"/> </system-properties> but both won't work (I check with EJBClient.getUserTransaction( node-name ) ) but get the error "No EJBReceiver available for node name MyNode". If I set <server name=> getUserTransaction still need the default-host-name. But if I check inside my bean with "System.getProperty("jboss.node.name") the name is set and if not default to my host name. The mngmt console show the server name and if I set both the console show the server-name and the property inside of an application the system-property. ==== domain ==== I try to check whether the <server name=""> work and use also the system-properties element inside each server. But both attempts won't work (with EJBClient.getUtx). The server name from the configuration is shown always by mgnmt console and not reflect the system-properties setting, but the property inside the application is set by the system-properties element. ================== I'm confused because I expect that I can see the node name (as server name) in the console and use the <server name=> also for getUserTransaction. My Questions about: - what is the purpose of node-name (except user identifier for console), only a identifier for clustering? - Should the node-name in mngmt console and the property jboss.node.name get by an application getProperty the same? - am I right that it a bug that the node-name in standalone.xml or host.xml won't work for getUserTransaction and I should raise a JIRA? - is it possible that other functions are affected by this? - Wolf
