------------------------------------------------------------------
Summation of effort on this issue.
* The cause of the issue is described in the Mike's comment above
(https://issues.jboss.org/browse/WFLY-12317?focusedCommentId=13763985#comm...).
* Even the test worked before with {{:reload}} it was not correct and the correct
behaviour needed (even in WFLY16) restart. The counterexample is - start WFLY with node-id
{{1}}. Fill the object store with some transaction data (orphan detection needs to be
triggered). Wait a 2 minutes for recovery to start. Try to change the node-id to {{2}}
with cli operation and reload. Even the model and jboss cli shows the node-id is {{2}}
Narayana still effectivelly uses the node-id with value {{1}}. To fix this restart of the
JVM is needed.
* Question is what is the right fix. There is a discussion at the forum
https://developer.jboss.org/thread/280430 what is the right fix. I personally inclined to
permit to change the node-id just with reload (the fix would be then like this
https://github.com/ochaloup/wildfly/commit/c39536f621dd3be38fdc605cd3b884...). The
other option is to enforce JVM restart (the fix would be then like this
https://github.com/ochaloup/wildfly/commit/42d098a41e1f9e9854d080491849aa...).
So, for the test this means that it's wrongly written for WFLY16. It's not the
problem of the test as it follows the attribute description in the model. But as the model
description presents a wrong flag (reload requires instead of necessary restart requires)
it's the issue of the model that the flag was set wrongly. (The fix for this issue can
allow only the reload.)

Using JTA transaction's node_name attribute is set to an old

Key: WFLY-12317
URL: https://issues.jboss.org/browse/WFLY-12317
Project: WildFly
Issue Type: Bug
Components: Transactions
Affects Versions: 17.0.0.Final
Reporter: Ivan Straka
Assignee: Michael Musgrove
Priority: Critical
Attachments:
server1_TxDifferentNodeCrashRecoveryTestCase_prepareHalt_jta_server.log,
server2_TxDifferentNodeCrashRecoveryTestCase_prepareHalt_jta_server.log
We have following test scenario (3 servers) that fails:
# node-identifier of server1, 2 & 3 is set to 'vkcd', 'FdOu' and
'GocW' (ts.jbosstsX.node.identifier property)
# server2 is started, node-identifier is set to txdifferentnodeid and server2 is
stopped
# server1 is started, node-identifier is set to txdifferentnodeid and server1 is
reloaded
# server3 is running
# client call an EJB bean (where a transaction is started) on the server1
# the EJB sends JMS message to the server3 (broker)
# the EJB enlists dummy xa resource
# during 2PC the Server1 is halted when prepare on dummy xa resource is invoked
# we move server1 object store directory to the server2
# server2 is started
# the server2 is expected to rollback whole transaction
Transaction is unfinished because server2 has not performed rollback.

{code}
In the beginning servers' node-identifier are set to some value (lets say A,B,C).
Before test execution node-identifier of server1 and server2 is set to the same value,
let's say X.
I see in logs that the transaction's node_name is set to the old value (vkcd vs
txdifferentnodeid in the example below) on server1. Thus the server2 has not performed
rollback.

*When does the scenario pass*
When I run the TS with
{code:java}
-Dts.jbossts1.node.identifier=txdifferentnodeid
-Dts.jbossts2.node.identifier=txdifferentnodeid
{code}
the test passes (old and new node-identifier on both servers are same)
When step 3 slightly differs:
When restart is performed instead of reload op.
Server1 is reloaded. If it is restarted, node name is set correctly to txdifferentnodeid
*tldr;*
The problem is that server1 set TX node name to old value after node identifier is
changed and server is reloaded. If the server is restarted, everything is OK.
