Tomasz Adamski commented on WFWIP-218:
--------------------------------------
In this scenario, the transaction is recovered (committed) correctly. The server waits for
the client before scale-down as well. The problem is that during the recovery the logs on
the server-side are not being cleared (because XAResourceRegistry is not serialized; null
in code below).
{code}
try {
if (commitToEnlistment()) lookup(xid).commit(onePhase);
} catch (XAException | RuntimeException exception) {
if (resourceRegistry != null)
resourceRegistry.resourceInDoubt(this);
throw exception;
}
if (resourceRegistry != null)
resourceRegistry.removeResource(this);
}
{code}
This is a bug but it does not cause incorrect transaction recovery. As a result, I'm
downgrading it from the blocker status.
server scale down keeps data in client's data/ejb-xa-recovery and
transactions on client aren't commited

Key: WFWIP-218

https://issues.jboss.org/browse/WFWIP-218
Project: WildFly WIP
Issue Type: Bug
Components: OpenShift
Reporter: Martin Simka
Assignee: Ondrej Chaloupka
Priority: Blocker
this follows up on WFWIP-206
While testing tx recovery in OpenShift I see that scale down of pod that has transaction
in-doubt on it isn't successful
Scenario:
*ejb client* (app tx-client, pod tx-client-0):
* EJB business method
** lookup remote EJB
** enlist XA resource 1 to transaction
** enlist XA resource 2 to transaction
** call remote EJB
*ejb server* (app tx-server, pod tx-server-0):
* EJB business method
** enlist XA resource 1 to transaction
** enlist XA resource 2 to transaction
*testTxStatelessServerSecondCommitThrowRmFail*
ejb server XA resource 2 fails with {{XAException(XAException.XAER_RMFAIL)}}
Then the test calls scale down (size from 1 to 0) on tx-server pod. Server scale down
completes but sometimes there some records left in
{{<JBOSS_HOME>/standalone/data/ejb-xa-recovery}} on tx-client and transactions on
client aren't commited.
