WARN  [org.jboss.as.txn] (ServerService Thread Pool -- 60) WFLYTX0013: Node identifier property is set to the default value. Please make sure it is unique.

The default standalone.xml/standalone-ha.xml file doesn’t have the node-identifier value, you need to configure node-identifier attribute in transactions subsystem for avoid wrng message in logs.

node-identifier="any_unique_identifier", like below.

        <subsystem xmlns="urn:jboss:domain:transactions:3.0">
            <core-environment node-identifier="eap7">
                <process-id>
                    <uuid/>
                </process-id>
            </core-environment>
            <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/>
        </subsystem>

     
You can give any value for this attribute, In this example, I have given eap7, because my JBoss server is eap7.

Note: If you are using doman mode then you need to update corresponding profile of transactions subsystem.
