JBAS010153: Node identifier property is set to the default value. Please make sure it is unique - jboss7.x

Question

I am getting the following WARN message while I start my host which is one of the Host Controller (HC) that is attached to the Domain Controller(DC).
[Server:server-two] 14:06:13,822 WARN [org.jboss.as.txn] (ServerService Thread Pool -- 33) JBAS010153: Node identifier property is set to the default value. Please make sure it is unique.
And my host-slave.xml has the following config...
<server-identities>
<!-- Replace this with either a base64 password of your own, or use a vault with a vault expression -->
<secret value="c2xhdmVfdXNlcl9wYXNzd29yZA=="/>
</server-identities>
I hope this config is the reason...... maybe I didn't understand..... but I couldn't find node identifier property rather this is the default secret value which I hope could be the cause of this WARN message.
However, I didn't mention HC to lookup host-slave.xml..... the command which I ran to start my HC is.....
[host-~-\-\-\bin]$./domain.sh -Djboss.domain.master.address=nnn.nn.nn.88 -b nnn.nn.nn.89 -bmanagement nnn.nn.nn.89 &
nnn.nn.nn.88 is my DC
Else please advise what's cause of the WARN message.
And please let me know the implication of this WARN message and advise us on the required config to overcome and sort out any consecutive consequences that would've been bound for this WARN.

Answer 1

I'm new to wildfly, and noticed this warning when I started it standalone from eclipse (I'm doing the following tutorial: https://wwu-pi.github.io/tutorials/lectures/eai/020_tutorial_jboss_project.html)
The fix was to add a node-identifier to the core-environment in the subsystem:
<subsystem xmlns="urn:jboss:domain:transactions:2.0">
<core-environment node-identifier="meindertwillemhoving">
<process-id>
<uuid/>
</process-id>
</core-environment>
<recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/>
</subsystem>
This is in file [wildfly]\standalone\configuration\standalone.xml.
This is the same answer as https://developer.jboss.org/message/880136#880136

According to WFLY-10541 if you are using WildFly v14.0.0 or newer you can pass the following to the startup script to set the transaction node identifier:
-Djboss.tx.node.id=<some-unique-id>

Answer 3

Setting the node identifier to an unique value is only required for proper handling of XA Transactions.
You can set it as follows in your XML configuration:
<subsystem xmlns="urn:jboss:domain:transactions:6.0">
<core-environment node-identifier="${jboss.tx.node.id}">
It needs to be a unique value up to 23 bytes long.

Answer 4

Building on #kaptan's answer I added the following to the bottom of
bin/standalone.conf:
JAVA_OPTS="$JAVA_OPTS -Djboss.tx.node.id=`hostname -f`
This way I don't have to remember to add the "-Djboss.tx.node.id=" when running up wildfly by hand.

Answer 5

For this <server-identities> is not the issue. In fact, it shouldn't be touched at all.
When JBoss is started in domain mode by domain.sh, by default there will be three servers server-one server-two server-three. When you are running one more HC attached to the DC.... the defaulted server which is in auto-start mode will get clash when we start HC attaching to DC,- by the following command.
[host-~-\-\-\bin]$./domain.sh -Djboss.domain.master.address=nnn.nn.nn.88 -b nnn.nn.nn.89 -bmanagement nnn.nn.nn.89 &
Or by having the host configuration at HC (default host.xml... until unless we choose a different one....).
<domain-controller>
<remote host="${jboss.domain.master.address:nnn.nn.nn.88}" port="${jboss.domain.master.port:9999}" security-realm="ManagementRealm"/>
<domain-controller>
In order to solve this, we need to turn auto-start to false..... And we need to create a new server-group...... To that group we need to add dc-created-server and hc-created-server..... we can choose the appropriate same profile either full-ha or full for both created servers across DC and HC.
SO when we start the group by configuring the required HEAP size including permgen space... You could start both DC and HC.... and in DC you could see both of your-created-servers are started in the created server-group.
DC- Domain Controller
HC- Host Controller
To deploy you need to upload .ear or web-archive in the Application Console. You cannot place it in the deployments folder as how you do in standalone mode with .dodeploy file.
If you upload the same .ear next version do the Replace option instead of the Remove & Add option in the upload process.
