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

Given how hard it can be to maintain unique numerical identifiers, especially in a large environment, perhaps it's a good idea to allow a pluggable assignment strategy.  Here are some ideas:

* Central registry such as...
** LDAP database
** DNS entry
** JDBC data store
* Perfect or imperfect hashing strategy such as...
** IP address mapping
** MAC address mapping
** Hardware serial number mapping

> 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.
