[jboss-jira] [JBoss JIRA] (WFLY-3042) There should be a warning logged if the default value of node identifier has not been changed.

[David Lloyd (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-3042?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12949081#comment-12949081 ] 

David Lloyd commented on WFLY-3042:
-----------------------------------

The point of making it pluggable is that the administrator is in a position to know whether, for example, the IP address is globally unique within their organization, or other such schemes.  Likewise with a database or other central registry, the administrator takes on any associated risk as a balance to the effort saved or the risk inherent in manual maintenance of a large environment.

In a domain, in particular, it is actually impossible to set up a unique ID per server in a server group (it uses the profile settings) unless you define a system or environment property on every host which is expanded in that hosts' server (which is potentially an even greater burden, especially if you have a very large number of servers).

> JBoss EAP instance is using the value of node identifier  to identify XA transactions that belong to it. By default this value is set to 1. Now days in most environments there will be multiple JBoss instances sharing XA resources there for it is necessary to set the value of node identifier to a unique value for each instance. This is something that most end users fail to perform. Therefor it would be helpful if  a warning  message was logged at startup telling the user to do it.
