SLSB with dependency on HASingletonDeployer / Barrier results in error message on second
node on startup
--------------------------------------------------------------------------------------------------------
Key: JBAS-7096
URL: https://jira.jboss.org/jira/browse/JBAS-7096
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Clustering
Affects Versions: JBossAS-5.1.0.GA
Environment: RHEL 4 Update 7 (and OSX 10.5.7), Sun JRE 1.6.0_12, JBoss 5.1.0 -
"all" configuration
Reporter: Richard Taylor
Assignee: Brian Stansberry
Priority: Minor
Basic cluster, two JBoss 5.1.0 nodes, "all" configuration. First node starts
fine. Second node starts, however at the end of starting, any SLSBs that depend on the
barrier result in an error being logged at startup (on the second node).
Example:
DEPLOYMENTS MISSING DEPENDENCIES:
Deployment
"jboss.j2ee:ear=app-ear.ear,jar=app-ejb.jar,name=BoardPollerMDB,service=EJB3" is
missing the following dependencies:
Dependency "<UNKNOWN
jboss.j2ee:ear=app-ear.ear,jar=app-ejb.jar,name=BoardPollerMDB,service=EJB3>"
(should be in state "Described", bu
t is actually in state "** UNRESOLVED Demands
'jboss.ha:service=HASingletonDeployer,type=Barrier' **")
DEPLOYMENTS IN ERROR:
Deployment "<UNKNOWN
jboss.j2ee:ear=app-ear.ear,jar=app-ejb.jar,name=BoardPollerMDB,service=EJB3>" is
in error due to the following reas
on(s): ** UNRESOLVED Demands 'jboss.ha:service=HASingletonDeployer,type=Barrier'
**
The SLSBs on node 2 do properly start in a failover scenario when node 1 goes down. So
functionally things seem OK. However the error message is a little concerning and it
leaves us wondering if there is more to the problem.

Scott Marlow commented on JBAS-7096:
------------------------------------
I might of recreated this issue in the Infinispan integration with AS 6 effort. It could
also be that I'm seeing something different but just in case, I'll add some notes
here.
1. I enabled trace logging in jboss-logging.xml
<logger category="org.jboss.ha">
<level name="TRACE" />
</logger>
2. I added more debug logging to the HASingletonController and family (I'm on a
private branch, so these changes won't show up for a bit).
3. The debug logging is showing that the singleton controller is make a selection using
DistributedReplicantManager.
4. The DistributedReplicantManager.isMasterReplica("HASingletonDeployer") is
returning true because no replicants are found for service
"HASingletonDeployer".
That is the evidence at hand, not sure of anything else. If others are hitting this
issue, trying enabling trace logging for "org.jboss.ha" and look for the
following server.log output. If you see the following, we are seeing the same problem:
2010-10-13 22:18:52,354 TRACE
[org.jboss.ha.core.framework.server.DistributedReplicantManagerImpl.DefaultPartition]
(AsynchKeyChangeHandler Thread) no replicants, key=HASingletonDeployer,
isMasterReplica=true
I'm not sure if the fix yet but wanted to share my findings in case we can learn from
them.
One thing that I'm curious about is if we could switch to using the ha partition
notion of being master instead. That would be the first (or oldest surviving) node in the
cluster.

------------------------------------
For another clue, look in the logs for value "add, key=".
I see hits for "FarmProfileRepositoryClusteringHandler" and
"HAModClusterService".
More worrisome, I don't see hits for "HASingletonDeployer", which probably
explains why we hit the "no replicants" case that returns true on both nodes.
Interesting...

------------------------------------
It looks like HASingletonImpl.registerDRMListener() didn't get invoked (I added a
log.debug call that didn't show up in server.log), which probably means that the
HAServiceImpl.start() didn't happen either.
Maybe this stuff is wired incorrectly.

Some of the above appears to be a logging issue but it still seems that the first node
correctly updates the DRM replicants but the second node doesn't see that.
