[jboss-jira] [JBoss JIRA] Commented: (JBAS-6307) Cross-cluster cross-talk on JBM-DATA channel
[
https://issues.jboss.org/browse/JBAS-6307?page=com.atlassian.jira.plugin....
]
Kevin Lohmann commented on JBAS-6307:
-------------------------------------
The file jgroups-channelfactory-stacks.xml in all\production\web server contains the
configuration
<MPING timeout="5000"
mcast_addr="${jboss.jgroups.jbm_data.mping_mcast_addr:228.6.6.6}" [..] />
So no improper syntax, but not the above given config
<MPING timeout="5000"
mcast_addr="${jboss.partition.udpGroup:228.6.6.6}" [..] />
Mean both values for mcast_addr the same?
Cross-cluster cross-talk on JBM-DATA channel
--------------------------------------------
Key: JBAS-6307
URL: https://issues.jboss.org/browse/JBAS-6307
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: Clustering, JMS (HornetQ)
Affects Versions: JBossAS-5.0.0.GA
Reporter: Brian Stansberry
Assignee: Brian Stansberry
Fix For: JBossAS-5.0.1.GA
The configuration syntax in the jbm-data protocol stack config's MPING.mcast_addr
attribute is not understood by the JGroups parser; it's syntax only supported by the
String property replacement code in jboss-common-core.jar.
<MPING timeout="5000"
mcast_addr="${jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup:228.6.6.6}"
will be evaluated by JGroups as "use value for system property
'jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup', if not found use
228.6.6.6". Which results in 228.6.6.6.
Fix is to replace with
<MPING timeout="5000"
mcast_addr="${jboss.partition.udpGroup:228.6.6.6}"
in which case setting -u at AS startup will set jboss.partition.udpGroup, which JGroups
will find and use.
