<div dir="ltr"><div>Dear John,</div><div><br></div><div>Suppose you have two JBoss instances running on one (the same) host (using e.g. port offset) identifying both would be done by explicitly setting the <a href="http://jboss.node.name">jboss.node.name</a> so this is expected behavior.

(In our development stage we have over 30 JBoss servers running on the same host, all being tied up to JGroups).</div><div><br></div><div>Regards Dennis</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jun 28, 2016 at 11:30 PM, John Mazzitelli <span dir="ltr"><<a href="mailto:mazz@redhat.com" target="_blank">mazz@redhat.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">There is some confusion about setting the WildFly node name (at least in the standalone server case).<br>

<br>
Suppose I start WildFly via standalone.sh (with its stock out of box standalone.xml) but with the command line option:<br>
<br>
-<a href="http://Djboss.node.name" target="_blank" rel="noreferrer">Djboss.node.name</a>=wotgorilla<br>
<br>
When I do this, I see the node-name (in the server-environment subsystem) set to "wotgorilla" but the server's name is my normal hostname (in this case "mazztower"):<br>
<br>
/core-service=server-environment/:read-attribute(name=node-name)<br>
{<br>
"outcome" => "success",<br>
"result" => "wotgorilla"<br>
}<br>
<br>
/:read-attribute(name=name)<br>
{<br>
"outcome" => "success",<br>
"result" => "mazztower"<br>
}<br>
<br>
OK, but now suppose I edit standalone.xml - in the top-level root element <server> I add the name attribute:<br>
<br>
<server name="foobar"><br>
<br>
and I start the server WITHOUT any commmand line options (just "standalone.sh"). I see that BOTH "name" and "node-name" match my new server name:<br>
<br>
/core-service=server-environment/:read-attribute(name=node-name)<br>
{<br>
"outcome" => "success",<br>
"result" => "foobar"<br>
}<br>
<br>
/:read-attribute(name=name)<br>
{<br>
"outcome" => "success",<br>
"result" => "foobar"<br>
}<br>
<br>
QUESTION: Why the discrepency? Is this a bug or expected behavior? How does one change the server's cluster node name (say, for the JGroups configuration). I thought both would be equivalent (either setting <server name="a"> or setting <a href="http://jboss.node.name" target="_blank" rel="noreferrer">jboss.node.name</a>) but that does not seem to be the case.<br>
<br>
Thanks,<br>
John Mazz<br>
